Motherboard SDIF Output Or Soundcard

Yes, Joe, they are an interesting company. Though I don't understand their rationale for not providing information regarding the sound qualities of their different models. After all, if they are doing something between models there must be a reason-hopefully, something that relates to increased sound definition.
In any case, I own the Bifrost Multibit and the Modi Multibit, I am very happy with both. I really can't see how much better the more expensive models could be, but I wouldn't doubt it. 
Now if I can just find a used Yggy...

I agree that the Schiit products offer great return for investment. Can't help to think that the Bitfrost Multibit would prove to be an improvement over the V90. Especially for the playback of redbook CDs as uncompressed computer files.

I would recommend an USB Interface and a USB isolator.  I use a Schiit Wyrd ($99) to isolate the USB signal from a noisy computer port and then a Gustard U12 ($160) to convert to spdif.  The Gustard has dual TXCO to minimize jitter and it sounds fantastic.  

Audioman, do you notice a significant difference using the Wyrd?

gdnrbob:  Yes there is a significant difference.  The sound is tighter with a lower noise floor.  USB ports on computers are VERY noisy devices and the Wyrd repeater helps.  What I like about it is that it uses a linear power supply (the adapter is AC) and then has precision regulation inside the unit.  It worked so well for me that I ended up buying a second unit to be used at my office.  For $99 it does its job well.  Even high-end dacs can benefit from it.
