Schiit DACs (Bifrost and Gungnir down, one to go)? The information and anticipation thread. - Page 223

post #3331 of 3335

I bought the Uber Analog and USB Gen 2 upgrades recently and installed them myself. Very easy and straight forward, though I think you're right with the potential of having to send the Bifrost in to be reprogrammed for a multi-bit board upgrade.

2. Upgrades may not happen? Are you seriously arguing it's better to spend a lot more money on a DAC that's designed to be thrown away when tech changes, versus getting one that offers insane price/capability/value even without considering upgradability? It's not like Bifrost requires a second mortgage.

 

And, uh, upgrades will happen.

 

So, what happened with this galvanic isolation thing?  The USB gen 2 board is quite noisy from a PC and will not run off an iPad without a powered hub.  Am I to assume it's not a "competently designed, non-bus powered" device?

I was at the SF meet and 2 people ran my Bifrost straight off their iphones through USB (otg)... no hubs or anything involved.  (It has usb gen 2. board)

 

Furthermore, the USB input isn't noisy in the slightest.  (Compared to the optical in).

 

Did you get a ground loop or something?

Yes, ground loops are the main reason for galvanic isolation.

Hi, guys! I'm not sure if this has been brought up before--I have a question about the USB male plug that goes into Bifrost. I mean, it should go all the way in, right? And not half-way? Should it make a click sound to signify proper connection? I'm unfamiliar with this male USB plug, and it seems loose when connected half-way and I can still see part of the metal rod, which is most likely the reason why connection information on the Sound and Audio Midi setup of the Macbook Pro disappears intermittently, and of course, the music stops. I tried exerting a bit of force to plug the USB into Bifrost but it doesn't seem to want to go all the way in. Right now, I'm connected with Toslink, which isn't giving me any problem at all. But since I bought a PYST cable for the USB, I thought I might as well make use of it. Anyway, is there a difference in quality between a Toslink or USB connection to source?
