Matrix X-Sabre DAC review and impression thread - Page 38

post #556 of 999

I just received my X-Sabre today.  I have a Macbook Retina and the USB was plug and play just like the documentation said.  My iTunes and Spotify sound good, and when I fired up Audirvana Plus and switched to my higher res music, it really came alive and sounded pretty fantastic; although I haven't tried my collection of amps/headphones yet.  Right now it's just my HE-6's and Emotiva amp.  :)

 

But, I did want to point one thing out though.  I noticed that when a co-worker sent me a youtube video, there was no sound.  I tried a couple of browsers and any sound that played in flash just didn't come through. While not super important to hi def audio, it certainly was annoying none the less.  I went into the Audi MIDI Setup tool and noticed that it defaults to an output format of 384k.  When I changed this to 192k, sound started playing through flash just fine.  

 

I haven't really checked any other reason that would cause the sound not to play in flash at 384k, but this is a quick workaround for those times a Mac user wants to hear their youtube videos.  ;)

Mine arrived here today, been warming it up for a few hours and getting the courage up to have a listen.

DO IT!!!!! You've got a nice system there, it should sound great.

Will X-Sabre benefit from a device like this http://vaunix.com/products/high-quality-usb-hub/overview.cfm or is it good only for DACs that draw power directly from USB?

post #561 of 999
I wouldn't use anything like that with the X-Sabre if possible. Direct line from computer to DAC is ideal.

Doesn't it use USB power? Usually USB powered receivers greatly benefit from things like iUSB Power, but if its fully galvanically isolated and don't rely on USB power line, it's fruitless.

No it has it's own power supply.

Thanks, just making sure by "it" you meant USB receiver, not the whole unit.

What are you talking about? There is one power supply for the whole DAC just like every other DAC out there. Within the X-Sabre there is the circuitry from the X-SPDIF so its USB input is very good.

The power supply could be for the analog portion of the Dac only. The USB section can either draw 5V from the USB port, or draw power from its own transformer. You'd be surprised to know many Dac cheaps out on the USB part =p.

 

The Eximus DP1 for example, the analog stage uses its own power supply, but the USB input (also XMOS) draw 5V from the computer usb port.

Thanks for chiming in, yep, unfortunately that's the problem with most USB DACs today, I really hope X-Sabre is different but pretty sure from what I've read on computer audiophile it's not. frown.gif

Not good...

On the bright side, it allows...  power supplies/battery rolling if the design is not to your liking tongue_smile.gif.

 

Most people didn't care where the XMOS get power from before iFi started touting their clean powaaaaa ads for the ifi usb anyway.

Chiming in on the USB power subject - as far as I can tell the X-Sabre gets power from USB, just like most other DACs. Plenty of well-regarded USB to SPDIF converters do as well: Audiophilleo (without PurePower add-on), Stello U3, Resonessence Labs Concero, and others. Yes, some of the more expensive ones like Berkeley Alpha USB and Bel Canto Ref Link use their own power, but then again those cost more than the entire X-Sabre. 

 

Personally I don't see it as a major problem. It's definitely one of those "last few inches" type of performance areas. The Anedio D2 USB input draws power from the USB line and sounds freakin amazing regardless. I suppose it could be an issue if your system has major noise issues though. Personally I'd say throw in a SOtM USB card or use the Vaunix USB isolator and call it a day.
