Meitner Audio Updates their MA-1 D/A Converter ($7,000) With the introduction of Meitner Audio's very first product—the Meitner MA-1 Stereo D/A Converter—cost-no-object performance has suddenly become a whole lot less costly. How did we do it? By utilizing the award-winning technologies Ed Meitner developed for our EMM Labs line of products. The result is a converter that turns the 'you-have-to-spend-a-lot-to-get-a-lot' paradigm on its proverbial ear? It also happens to turn your computer or media server into a high-end, high-resolution music-making machine. Re-introducing the MA-1 – built with the award winning reference technology in the DA1. The DAC2X features the latest generation MDAT2™ up-converting DSP, MFAST™ jitter removal system, MCLK™ master clock and Ed Meitner’s hand built 22.5792 MHz proprietary discrete dual differential D-to-A converters. Using technology developed in their flagship DA2, EMM Labs and Meitner Audio has once again updated both their multi-award winning DACs the Meitner Audio MA-1 DAC and EMM Labs DAC2X. In addition to being the perfect companion of their TSDX CD/SACD Transport, the updates provide a huge improvement in transparency, accuracy and overall sound quality. The new V2 unit updates consist of: MDAC™ in both platforms are now fully discrete DSD512/8xDSD D/A converters completely built in-house at EMM Labs' manufacturing facility in Canada Their multi-award winning MDAT2™ DSP has also been refined and updated to synergistically work with the new 8xDSD MDAC™. The new MDAT2™ DSP does real-time transient detection, processing and up-conversion of all incoming audio, PCM and DSD, before sending it to the new MDAC™ The DSD audio signal path has been re-designed allowing for further enhancements in transparency during the DSD to Analog conversion process Proprietary hardware galvanic isolation for the USB Audio interface Supports sampling rates of 44.1, 48, 88.2, 96, 176.4 and 192kHz at word lengths up to 24 bits through all 6 digital inputs, Support for DSD128/2xDSD and DXD streaming via USB Audio Support for DSD (DoP) streaming via TOSLINK, SPDIF and AES No configuration necessary, just plug and play. Every other digital system from its proprietary jitter removal MFAST™ to its super accurate clock, MCLK™ has also been carefully revised as well for better sound. MFAST™ asynchronous technology Feed the MA-1 through any of its six inputs and the revised Meitner Frequency Acquisition System (MFAST™) instantly acquires the signal, buffers it, then strips jitter out completely. A high-speed asynchronous system, it decouples input from output. MFAST™ ensures that you'll enjoy pristine sonic clarity whether the incoming data stream is pure oranything but. MDAT2™: 8x DSD (DSD512) upsampling From there, the signal goes straight into a new Meitner Digital Audio Translator (MDAT2™) which upsamples digital audio to DSD512, 8x the SACD standard sampling rate. The world's best dac/clock combination The MA-1 features an improved, standard-setting MDAC™ dual differential discrete D-to-A and MCLK™ high-purity master clock modules. Together, they're music to our ears and we bet they will be to yours too. Note - Please note the V2 units performance are immediately noticeable and not subtle. So it’s quite a big jump in performance from the standard MA-1to the V2 version. Most units purchased in 2016 would already have newer hardware and you can just update the unit with the finalized firmware to make it V2. We are also offering an upgrade package for customers with older MA-1s and DAC2Xs to upgrade their units to V2 (upgrade MSRP is: $1,750) If you aren't sure if your DAC already has the newer hardware, please contact us with the serial number to check.

EMM Labs Updates their Award-Winning DAC2X D/A Converter($15,500) You know how it is. Digital audio data isn't the sole domain of digital transports any longer. Today, digital audio streams from sources as diverse as your PC, music server, satellite receiver, mixing board and portable player. Which is why EMM Labs has created one very simple, very convenient way to get state-of-the-art sound from all of them. Re-introducing the DAC2X – built with the award winning reference technology in the XDS1. The DAC2X features the latest generation MDAT2™ up-converting DSP, MFAST™ jitter removal system, MCLK™ master clock and Ed Meitner’s hand built 22.5792 MHz proprietary discrete dual differential D-to-A converters.

Together, they're music to our ears. Yours too, as an audition will quickly prove. MFAST™ vs. conventional PLLs Most converters utilize PLL (Phase Locked Loop) circuits. MFAST™ has two distinct advantages. It's a high-speed asynchronous system that locks almost instantaneously to any data stream. Moreover, unlike PLLs which merely attenuate jitter, MFAST™ strips jitter out of the audio stream completely. Enabling you to enjoy pristine sonic clarity whether the incoming data stream is pure or anything but. Proprietary discrete dual differential D-to-A conversion circuit EMM Labs remains unwilling to accept the inherent non-linearities of every mass-market chip created to date and they believe you neither should you.

I use a Rotel RC-1590 preamplifier with an embedded DAC. The DAC uses an AKM Premium 32 bits 768 kHz DAC, probably an AK4495. I play music from Audirvana+ 3.0.7 from a MacBook Pro with macOS Sierra 10.12.6. When I play PCM music, everything seems to work fine, but when I play DSD audio, a click sound can be heard at the beginning and at the end of the playing. The same happens when I play music from the MacBook with Roon as an output. In both cases I use DoP 1.0. I also have attached a Roon Core over Linux using DoP 1.0 and the same happens there. I don't know if it is quite common this click sounds when playing DSD audio or, on the other hand, it is something related with DoP, Rotel or AK4495 chip. I have not tested the system from a Windows box with native DSD.

Hi , the reason I started this topic was because of the question I had in my mind and couldn't find an answer elsewhere . I have a ifi nano idsd dac and because of firmware limitation (5.2 vs 5.3) I have to choose between MQA decoder or DSD256 in DoP mode . since I have a roon hqplayer setup , I wanted to ask if it is worth to stick with mqa and DSD128 DoP or it is better to use no-mqa and DSD256 DoP and upsample everything (mqa and non-mqa songs) with this setting in hqplayer ? p.s : Sorry for my rusty English 😬🙏

Hi all -- first post, total noob. I have been trying to get DSD via AES/EBU into my W4S DSDse. Is DSD available via AES, or only USB on this DAC? So far, I've only been able to get DSD DoP to work, which shows AES/EBU 176k4 on the screen. I'm running JRiver on a Win 7 machine with a Lynx AES16e board installed. Any insights welcomed. Thank you in advance for sharing your time and expertise.

I found that when playing dsd files, dac can only get PCM signals. Could I make it locked in dop mode when playing dsd? Don't know if these lines can help. root@DietPi:~# cat /proc/asound/card1/stream0 AUDIOBYTE BLACK DRAGON at usb-aotg_hcd.1-1.1, high speed : USB Audio Playback: Status: Running Interface = 2 Altset = 1 Packet Size = 127 Momentary freq = 95997 Hz (0xb.ffe4) Feedback Format = 16.16 Interface 2 Altset 1 Format: S32_LE Channels: 2 Endpoint: 5 OUT (ASYNC) Rates: 44100, 48000, 88200, 96000, 176400, 192000, 352800, 384000 Data packet interval: 125 us And if I use ssh to tap in "squeezelite -D", system returns nothing, seeming like stuck.
