  1. Here is the Roon KB article on multi-channel and two test files. https://kb.roonlabs.com/Multichannel
  2. May I ask for the serial number of your device?
  3. jmdesignz2 when you email back to us can you also refer to this post so we can cross-reference your requests on CA and our customer support management system.
  4. I was also wandering why we don't see your request. Please email us at customerservice at exasound dot com.
  5. If you need support contact customer service - exaSound Audio Design > About Us > Contact Us

  7. Actually Mini-XLRs are much smaller on the inside than 1/4 connectors. A word clock will cause jitter increase. Further it goes against the very idea of asynchronous operation. We've made our DACs on purpose asynchronous, or not synchronized with the outside world. In our view this is the best way to maintain the highest timing accuracy. If we do it the other way the sonic fidelity won't be the same.
  8. Yes, it is a universal law of electricity. Devices pull out just what they need regardless of the maximum current rating of the power source. But when you raise the voltage they pull more current... In practice 13.8V is fine, except in extreme circumstances. You will be exceeding the voltage requirement. If you exceed another one, for example ambient temperature you can get in trouble. It makes sense to use a battery that operates in the range between 11 and 14 Volts because batteries are excellent power sources and this is the way they work. With a battery the DAC is not exposed all the time to higher voltage. It is not a good practice to use a regulated power supply that is rated for higher than 12V. Further if your power supply is not regulated you shouldn't use it. Another concern is safety. To comply with safety codes you need to use an 1.5 Amp fuse on the output of your power supply.
  9. Our drivers work the same way, and the configuration is the same since then. The confusion comes from the fact that exaSond DACs (except for the latest DoP option for e32/e38) always work in native DSD mode. The Core Audio driver accepts DoP stream from the player, strips the DoP markers and sends over USB the native DSD stream. We will think of a better way to explain it in the Owner's Manual. With ASIO the advantage is that there is no need to do the conversion. ASIO also offers better asynchronous operation and Integer mode is guaranteed regardless of the Mac OS version.
  10. Hi Bob, The exaSound Core Audio drivers support native DSD up to DSD256, therefore there is no need for DoP. Native DSD works fine with Audirvana. The new ES9028 DAC chip supports DoP. I couldn't think of any application for it at this time.
  11. I've listed these in another thread: Lower noise Lower distortion Faster locking when sampling rate is changed Faster switching between inputs More stable and consistent processing of DSD128 and DSD256. Inputs can be selected from the Dashboard New drivers and firmware DoP support, if anybody needs it. Front plate cosmetic enhancements The old ES9018 had to be handled with custom settings under controlled hardware conditions to be able to play DSD256. It was possible with very limited room for customization. The new ES9028PRO allows more freedom at the top sampling rates and can be further fine-tuned.
  12. The real DSD files are not upsampled, only the fake ones.
  13. New e28 Mark II features include: Auto–power up after sleep User adjustable power down after inactivity Maximum volume limiter allows the e28 to directly drive a power amplifier while protecting your loudspeakers from damaging overloads MP3Safe™ software protection against clipping caused by faulty or erroneous signal processing and data manipulation. MP3Safe analyzes incoming musical information, and safeguards against poorly formed data words caused by errors in lossy encoding and digital signal processing. MP3Safe takes the crunch out your lower resolution music The ability to extinguish the display light via the e28’s included IR remote for no visual distractions while listening Redesigned, more substantial and deeply sculpted front plate A 12V trigger output has been added for amplifier sequencing and automation
