January 2018 - Axiom ditch the wires - Axiom announce a new wireless speaker line based "on the best-selling models in the existing line, offering built-in driver-matched gain and an app/web interface for streaming audio and preamp controls. Consumers can connect the small transmitter module TRP-1 to existing peripherals via the analog input, optical input or WiFi. They can also stream music from their networks or web radio and control it all from any device using Airplay (Apple), UPnP (Android, Windows) or the AxiomAir interface. Grouping two or more pairs (or adding a pair to one of the company's existing wireless AxiomAir N3) makes the entire system multi-room capable. Users can play the same song in every room or different songs in different rooms and control playback and volume from the UI. Each wireless model (two bookshelf and 3 tower models) contains a receiver module to wirelessly receive the audio signal; and a power amplifier. The speakers plug into a standard household outlet and deliver from 60 to 600 watts. Unlike other speakers that send the audio signal over a user's WiFi network, taxing the router and potentially leading to dropouts, the Axiom Wireless speakers use a dedicated closed system that runs on the 2.4Gz band but won't interfere with WiFi traffic. For even fuller sound, customers can add one of Axiom's three new wireless subwoofers."

December 2017 - Loudness wars go bust? - Music Streaming service Tidal has adopted the loudness recommendation of Eelco Grimm, HKU University of the Arts Utrecht and Grimm Audio. In Tidal's recent update of their iOS and Android apps, loudness normalization is now turned 'on' by default. With this move Tidal follow the trend towards automatic loudness normalization that was initiated by Spotify and Youtube. Eelco Grimm explains: "Tidal wanted to offer an optimal listening experience by adding loudness normalization but was concerned to interfere with the artistic intention of the producers. So I analyzed the loudness of 4.2 million albums from Tidal's database and found that even with recent releases quite large loudness differences exist between soft and loud tracks of the album. By normalizing all tracks to the same level, these differences are removed and the listener does not have the intended experience. A so-called 'album normalization' method, where all songs are adjusted with the same offset, solves this problem. The research question now was if these level differences between songs would still be appreciated when the tracks are mixed with songs from other albums in a playlist. The outcome of my subjective test was that the majority of users preferred album normalization always even when soft songs from one album are played next to loud songs from another album. The database analysis further suggested that on mobile devices the loudest track of the albums should be aligned to -14 LUFS.

"Tidal adopted album normalization at -14 LUFS and followed my recommendation to turn loudness normalization on by default. This is not only convenient for the listener but also helps to end the Loudness War since there is no longer any advantage to squashing the life out of a master. Such a track will just be attenuated more in the Music Streamer's app and make less impact than a dynamically mastered track. I am very excited about this development. The majority of music consumers worldwide now listens to loudness normalized music. I hope that the few remaining streaming companies that do not offer loudness normalization by default will follow soon."

October 2017 - Burning Amp Festival 2017 - It is coming to the Fort Mason Center in San Francisco on Sunday, November 12th from 8:30 a.m. to 8:00 PM. New this year are extended hours due to increased interest and popularity of DIY audio. Held in the fall since 2007, BAF has grown into a premier international event for DIY enthusiasts and professionals. DIY audio is the original maker movement dating back to the 1940s and 1950s when hifi was in its infancy and a lot of great-sounding equipment was assembled at home by enthusiastic amateurs.

BAF celebrates audio technology both new and old, tube and solid state, analog and digital. The festival has been held in the fall since October of 2007. Come listen to hand-built audio amplifiers, speakers and more. Bring your own gear: DIY amps, speakers, turntables, DACs, servers etc. Share ideas and learn to design and build your own equipment. By way of encouraging people to bring their own projects for show or demonstration, there will be free admission to anyone bringing a DIY project. There will be displays, demos, auction and raffle items, freebies plus well-attended lectures by prominent figures like Nelson Pass, Siegfried Linkwitz, Damian Martin and Wayne Colburn. And there are numerous DIY giveaways: Nelson Pass, as always, will generously contribute a big batch of Amp Camp amp circuit boards, parts and loudspeaker drivers. For more information or questions, follow the Burning Amp 2017 thread. When driving to the site, enter via the Gatehouse at Laguna Street and Marina Boulevard.
There are four talks throughout the day at the Firehouse. Unfortunately the room cannot accommodate more than about 110 people due to the Fire Code so some may have to stand outside or will not be able to attend a talk if they are late. No standing around the walls as this will violate code. Nelson Pass will be talking about his new amplifiers which diyAudio will sell as kits and should have them to demo along with tons of other stuff including the SAL speakers in his audition rooms. Siegfried Linkwitz will give a presentation on audio perception and demo his LX series open baffle speakers in his audition room.

Damian Martin will demonstrate the only existing US sample of a new precision measurement interface for computers which has unheard-of-performance per dollar; and a device designed by Jan Didden that automatically sets the input voltage to your computer interface to 1 volt to get the best measurements and not blow it up. He will have them on display at a table in the Firehouse and may do some tests of amps for people to demonstrate them

Wayne Colburn from Pass Labs will be about his new headphone amp design and the PCB he can supply for them and how he approaches some common circuit design issues. He ill also have a table in the Firehouse where you can listen to it. Bring your own headphones for the most meaningful experience.
October 2017 - Return of the AKG K-1000? - New and improved that is. The original two engineers responsible for this long discontinued headphone got back together to revisit the concept with new materials and other advances. One big advance is 96dB sensitivity. Impedance is 15 ohms, the driver is a 40mm square dynamic with 4mm of stroke. Approximate weight without cables is 330g. The pads attach magnetically and all frame adjustments are fluid not click-stopped. Pricing will start at $3'500 when shipping begins.
October 2017 - McInt - McIntosh announce their smallest MA5300 integrated amplifier [$5'000] whose direct-coupled circuit generates 100/160wpc into 8/4 ohms and includes MM phono, a comprehensive modular 384kHz/DSD256 DAC, a preout/main-in loop and a headphone amp with crossfeed circuitry.
October 2017 - Diamond cantilever? - Yes if you buy a Transfiguration Proteus D cartridge [£6'750]. "Production of a diamond cantilever is a unique challenge," explains designer and builder Seiji Yoshioka. "Of course it’s expensive but more than that, to craft it requires an extremely highly skilled technician." In most other respects, the design and specifications of the 'D' largely match those of the standard Proteus with its patented yokeless double ring-magnet design in which pure 99.9997% silver wire coils are positioned right at the focal point of the magnetic flux field. Multi-layered double dampers are made from different types of elastomer. Insensitive to temperature changes, they provide excellent stylus/coil alignment and control with highly precise tracking ability. The double dampers in the new limited edition Proteus D have been re-designed for the diamond cantilever."
October 2017 - Manhattan gets posher - Mytek's new Brooklyn DAC+ [$2'195] "features redesigned and enhanced conversion, analog and power supply circuits, the new Sabre 9028Pro chip for enhanced resolution and better filter options, upgraded headphone amplifier, better L/R separation, larger capacity power supply and new, very transparent analog attenuator circuit."
October 2017 - Acuhorn - Wojciech Unterschuetz of Polish audio house Acuhorn introduces their new Rate amp [€2'500] and matching R2R DAC/streamer [€3'600]. The stereo amp combines Lundahl input transformers with a Texas Instruments class D amplifier, Vicorpower SMPS and rear-mounted attenuator. The 28/384kHz DAC combines a 3.072MHz upsampling FPGA with a Soekris discrete R2R module and Raspberry Pi server again with a universal-range Vicorpower SMPS like the amp.
October 2017 - Gekko Cables - London-based Gekko Cables promote their Purple Haze interconnect as using "custom made one-piece connectors which use the core conductor to make contact with the equipment's RCA sockets."
October 2017 - Eureka - Richard Cesari of French cable house Esprit bows his new Eureka range which is positioned between their Lumina and Gaia models. " All models in the Eureka range are polarized and equipped with twin-material ferrites to eliminate ultrasonic frequencies and continue with our use of partial shields and air dielectric. A new pure copper conductor is clad in 40 microns of pure silver, then finished with new triboelectric surfacing to improve conductivity. All our cables are now available in black or white finish."
October 2017 - Auteur - Starting at $1'399, ZMF's forthcoming Auteur is billed as their first open-backed headphone with custom biocellulose 300-ohm driver. Standard trim is teak wood with black aluminium weighing 475g. Two different kinds of easily swappable ear pads are included to provide the user with different tuning options. Forthcoming editions will introduce other wood species with a choice of black or brass grille and rods.
October 2017 - Rad new Raidhos - The X-5 [starting at €26'900/pr] and XT-5 [starting at €39'600/pr] are the Danes' latest models which pair their ribbon tweeter with latest-gen Ceramix cones which "offer a step change in performance over previous versions to maximize power and power handling." To approach their own diamond membranes, the D-Series drivers exploit a new Titanium/ceramic sandwich which "starts with our existing three-layer aluminium/ceramic composite, then deposits on each side two layers of Titanium and Titanium Nitride particles in a high-temp sputter process for a seven-skin membrane of constrained layers." Refer to their website for more tech details.
September 2017 - New Metrums - Launching today at the Dutch XFi show are the Metrum Acoustics Onyx [€2'062 ex VAT] and Jade [€2'475 ex VAT] which slot into the expanding lineup between the Amethyst as the entry model; and the Adagio/Pavane at the top. Both run on two Transient Two ladder DACs per channel but the Jade adds precision volume control via variable reference voltage.
September 2017 - Bigger badder power plant - PS Audio announce their new P20 Power Plant, "our next step in power regeneration, offering lower distortion, lower output impedance, more output devices and greater current capacity than any product on the market. The P20 also features a unique new graphical user interface (GUI) which provides more information on both input and output signals than ever before."
September 2017 - Wyred's nextGEN class D - Here is a sneak peek at the guts of their proprietary new flagship amp with ground-up class D implementation, i.e. not any OEM module from ICEpower or other vendors. The big toroidal transformer and filter caps indicate a linear not switch-mode power supply. The fully dressed public premiere of it will be at the October RMAF show in two weeks.
September 2017 - Keep thy signal paths short - Ivo Linnenberg is getting his new reference monoblocks ready for their public unveiling at October's Westdeutsche Hifitage in Germany's city of Bonn. The Liszt will be high-power versions of his existing 55-watt Allegro monos. As this spy photo shows, the circuitry is again very tightly 3D packed to shorten the signal path for best bandwidth. The front third of the enclosure is taken up by the big power transformer whilst the output devices are mounted to the rear plate with its external heatsink. The obvious companion piece to the Liszt monos is LinnenberG's new Telemann DAC/pre with remote-controlled analog precision volume.
September 2017 - CAD USB - Computer Audio Design release their I and II cables. "A USB cable is made up of four conductors: two for power (+5V and ground), two for high speed differential data (data+ and data-). Unwanted high frequency noise is present on all. CAD’s patented filtering system carefully tackles all four. Since the +5V conductor carries particularly large amounts of HF noise, we use a separate highly-shielded cable for the +5V conductor. Also, our conductors for high-speed signals employ quite different materials and construction techniques to those that only operate at lower frequencies." Their new USB Cable I [£540] is an enhanced version of the original design. The USB Cable II [880] takes noise reduction considerably further with a whole different construction and insulation plus three independent CAD absorbers designed to further reduce unwanted high frequency electrical noise and mechanical vibration.
September 2017 - Aqua get even wetter - Aqua Hifi's Formula DAC gets the xHD makeover via new firmware for the main FPGA; and a new USB board with hybrid 2-stage XMOS xCore XE216+FPGA architecture. This means fully floating isolated USB decoding and clock generation via FPGA with proprietary code; and 768kHz PCM and DSD256 bit-perfect sample rates. The update involves a new plug-in USB module; hardware modification of board P1108 connected to the module; new firmware for the R2R ladder DAC FPGA; and new firmware for the STM32 main micro controller.
September 2017 - Hafler ship - Canada's Hafler, now a division of Radial Engineering Ltd, have begun shipping their $1'300 HA75-DAC, "an audiophile-quality 12AX7 based headphone amplifier and USB DAC with source impedance adjuster". 
September 2017 - SotM ready master clock - With their USB reclocker featuring an optional word-clock input, it was only a matter of time until the South Koreans would offer their own dedicated word clock. At right is a rendering of a prototype to be previewed at the upcoming RMAF show in Denver. It will have 4 x 50Ω BNC terminals (one 75Ω option), 10MHz operation and a 12V DC power input. Styling will copy their existing range of USB reclocker, mini server and linear power supply.
September 2017 - Japanese 3-2 combination - Chris Sommovigo's Black Cat Cable boutique have launched the new 3200 Series cable which begins shipping in mid November at $499.95/1m/pr (at $100 more by 2018). "The combination of Sommovigo’s Matrix-32 4-pole/32-element braid of individually insulated pure copper conductors and a processed Airwave twisted pair inside a thin-walled pure PTFE air-filled tube is simultaneously very complex and yet elegantly simple."
September 2017 - Go sutty not slutty - "Unlike most step-up transformers (SUT) customized to a specific cartridge with few adjustments, Zesto Audio's Allasso is the most versatile, with 40 mono adjustments and 40 for your stereo MC cartridge. All adjustments are easily accessible on the front and can be done on the fly without clicks or pops. The most prized features are the 4 gain settings of 17dB, 21dB, 23dB and 26dB and the stepup ratios of 1:4, 1:6, 1:8 and 1:12 with 10 load positions for each."
September 2017 - Nagra HD preamp - After 3 years of R&D with a 10-strong team of engineers, Swiss Nagra Audio are about to bow their new flagship tube preamp [€54'900] with outboard supercap power supply and integral mechanical decoupling system. There are 3/2 RCA/XLR inputs, one each RCA/XLR variable outputs, one fixed RCA output, a pair of XLR inputs which bypass the internal dual-mono transformer volume control, and selectable grounding for the main outputs. The two volume controls are clutched for normal operation, can be offset to dial in balance and, with a switch, can be reset to normal. Claimed specs are 160dB S/NR and 200kHz perfectly phase-linear bandwidth from a tube circuit. More information to come, with first public appearances planned for the upcoming hifi shows in Tokyo, Vietnam and Denver/US.
September 2017 - Meadowlark sings again - For those wondering what Pat McGinty has been up to since the original Meadowlark Audio closed its doors, their low-key new website shows a major shift of design approach: to 24/96 DSP-controlled fully active models in fact. The latest Kestrel now is a 2x250wpc twin 7" woofer affair in a 9 x 9 x 40" cab, with performance that "used to take a Heron level speaker with very good amps." With Pat's main business today being custom architectural wood trim for period homes, interest from custom installers knowing about his past had led to one-up speaker commissions. Those speakers had to be small yet potent. This led Pat to investigate the most current class D amps and DSP engines. Far more impressed with the result than he initially expected, he next applied the same thinking to the type speaker he'd designed before. The outcome is a small made-to-order boutique operation which he runs together with his daughter in parallel to their main architectural commissions.
September 2017 - Taga go hybrid - The HTA-1200 80wpc integrated combines a 12AX7 preamp and 12AU7 buffer stage to drive four Toshiba pure current-gain output transistors from a 300V transformer.

September 2017 - Lio's new DAC - This modular DAC2 with its three circuit boards can replace the DAC1 in Vinnie Rossi's integrated Lio platform. The top PCB is the left channel, showing the discrete Class A output stage and linear voltage regulators for the output stage and converter chip. The middle board is identical but handles the right channel. The bottom PCB contains the digital inputs, Xilinx FPGA, oscillators, reclock circuit, control firmware and linear regulators for various voltages.
September 2017 - Vermeer - "It is a pleasure to announce that a new version of our Vermeer Audio Two is ready to launch as the TWO Universal Control Center LAN. This model has the same specs as the TWO but adds a LAN/network input to convert our DAC/preamp platform into a high-end music server that will process Internet radio as well as all files located on a LAN, NAS or personal computer. Remote control is via iOS/iPad app. Also, the Two in all its versions is now equipped with Black Path capacitors developed by our partners at Convergent Audio Technology."
September 2017 - B&W 700 - "This new 700 speaker series sees the implementation of technology first seen in the high-end 800 Series Diamond: the Continuum midrange driver, a bespoke version of the Aerofoil profile bass driver; plus improved tweeter-on-top housings for the two flagship models crafted from solid aluminium billet. Both were first seen on the 800 Series Diamond. More new tech comes in the shape of the carbon-braced tweeters. This delivers sweeter cleaner performance even further up the audible bandwidth. The new range comprises eight models, two with tweeter-on-top technology including the flagship 702 S2. There are three floorstanding models, three standmount speakers and two dedicated centre channels. All models are available in gloss black, satin white or rosenut finishes. Pricing starts with $1'200/pr for the smallest monitor and tops out at $4'500/pr for the biggest 3-way vented floorstander."
September 2017 - Cubism - Grzegorz Rulka introduces their Cube Audio company from Poland where they "manufacture widebanders and loudspeakers based on them.

August 2017 - SAG - Simon Lee, formerly of April Music, is prepping the launch of his new portfolio. "Within two months, we expect samples of our small CD/DAC and integrated, our full-sized preamp and power amp and there are even two speaker models awaiting launch time." Given Mr. Lee's prior track record, one expects high-value product of unreasonably high sound quality. Those curious before the website launches can already reach Simon at simon55kr @
August 2017 - ET wanna go home - conrad-johnson's new ET-7 preamp [$9'500] doesn't mean a remote star but your system. "It incorporates advances in regulated power supply design debuted in our GAT Series 2 line stage while closely following the GAT audio circuit. The ET7 boasts the same extreme quality parts. CJD Teflon capacitors are used throughout the audio circuit and for the regulated plate voltage power supply filter and storage capacitors. In the interest of bringing GAT-like performance to a more affordable price, the ET7 reduces the total capacitance in power supplies and output coupling. Like the GAT Series 2, the ET7 uses all Vishay resistors in the audio circuit and in the associated power supplies. The ET7 replaces the discontinued ET5. Deliveries have already begun."
August 2017 - Polish SET - Acuhorn introduce their new TT amplifier which works its 6C33C at 400mA in auto bias. The amp can be run in stereo [€4'800] or converted to mono [€9'600 for the pair]. "The switching 90-264V/AC power supply is by ultra state-of-the-art Vicorpower modules.
