Hum can be caused by ground loop. Try to use Schiit power cord with so called cheater plug.    http://en.wikipedia.org/wiki/Cheater_plug

Quote:   Project86,   Have you tried DA with headphones connected to it? My DA8 does get hot but not too much when its built-in amp is on and feeding HE-400. Volume was set at 70-80% - don't remember exact figures in dB. When used as a pure DAC (with preamp disabled) it is barely warm...

Quote:   Do you really believe in what you wrote about Sooloos? $7000 for this children's toy? The price is really "high-end" but components and the technical part of audio design are ridiculous. I'm sure that SQ wise it is even not close to ANY of CAPS digital transports and will not...

Thanks for as usual very detailed answer. My WD is 2TB so I will stick to it. Good point about moving portable HDD around plus much faster speeds when adding new albums to it on Windows computer.

Quote:   John, What external HDD would you recommend? PK90 has only USB2.0 so no sense in utilizing external HDD USB3.0?  In my current Windows based setup I utiIize WD Passport USB3.0 but not sure if it will work with PK90? I mean, will HDD formated on Windows work with PK90?  ...

Quote:   Yes, I was considering CAPS but for utilising it with OS based on Windows. Unfortunately I'm not literate with Linux so that's I why was looking for a complete solution with pre-installed foolproof Linux with MPD. So, Auraliti seems to be the right choice for me.    By the...

Quote:   OK, thanks.

Thanks very much for quick and detailed answer!    One more question. Is NuForce LPS-1 a direct plug-in to PK90 or I will need to make some mods?

Quote:   John,   Thanks to your post hear and excellent Yulong Sabre DA8 review I'm now very interested in AuralityPK90-USB. Another reason is that my NuForce LPS1 getting dusty  as I switched from NuForce Icon HDP to Yulong DA8 - again thanks to you .     My current setup is...

Quote:   Quote:   Reply by Project86:   That was the case until a few years ago, but is generally no longer true. A well done asynchronous USB input can have lower jitter and be less transport dependent than even the best SPDIF implementations.   The DA8 uses a proprietary...

Quote: Project86, Looking forward for your review! Sure it will be very useful for us. Thanks a lot for sharing with us your priceless expertise.

Quote:   Will you have a chance to compare DA8 with Matrix X-Sabre? I believe that many of us very interested in this test. 

Quote: Thanks for the answer, Project86. I'm surprised to hear that USB sounds better than SPDIF as a general rule SPDIF is always better that USB. Or maybe in DA8 SPDIF input just very average and not on a par with USB? 

I'm very interested in DA8. I use asynchronous converter Nuforce U192S plus Icon HDP with linear power supply LPS-1. Icon HDP output is used with HE-400 or Marantz PM-6004 with MA Silver RX2.    I have two questions: 1. Is power supply in DA8 linear or not? I'm a bit confused as external...
