I have some incoming Schiit.  I got uprade-itis, so today I placed an order for the Bifrost Uber with USB.  I wanted a more dogmatically vigilant DAC, and I'm pretty sure this will do the trick.  My V-DAC II will join the bedroom or office rig.

Uhm, now I'm tempted as well. I have the V-DAC II too. Let me know how it sounds compared to it.

Will do.  I do like the V-DAC, but the one thing I don't like (and this is an extremely small point) is it lacks a little bite in its attack.  Also, sometimes it lacks some depth and loses a little focus during complex passages.

 

Everything I read says the Bifrost Uber will be better.  Plus, being upgradeable is huge for me.

Hmm, do you have an upgraded PSU with V-DAC?

I do.  I can hear slightly more bass and less etchy treble, but the end result is not breathtaking like some reviews may suggest.

OK, let's see how it goes with Bifrost for you. Then I might pull the trigger as well.

A PSU (Power Supply Unit) should influence noise, hum, possibly interference from the power line. How is that going to affect bass or treble? A really bad PSU might drop voltage under load in an amp, but not in a DAC.

I heard weak PSU can increase source impedance in low frequencies? Does it make sense?

A weak PSU might drop voltage under load, if that's what you mean by weak. I can't see that being a problem in a decent DAC. A low supply voltage would probably cause more serious problems. LIke I said the possible issues would be noise, hum and interference. How is the power supply of a DAC going to affect the impedance of what you plug into it?

We are easily influenced by what others say. Some people start stuff for going for the oddest reasons and it takes on a life of its own. This is human nature, more so with audio kit. All too often people are hurt by the chatter. I feel bad when I see this happen to others.

Would one notice a difference between the older Bifrost and the new "uber"? I am using AKG K702 + Asgard.

Not in your case probably

The 702s are extremely revealing, so I'd say there would be an audible difference.

Even though I bought my Bifrost with the Uber option, I'm not sure if a human being can hear the difference. The differences in distortion are in the thousandths of a percent. The distortion figures for the basic Bifrost are so far below perception that any improvement is for the benefit of spec sheets and lab equipment. I'm not sure of how many people could tell the difference in noise levels, if so they might have to squeeze so hard as to injure themselves.


Bifrost:
Frequency Response: 20Hz-20KHz, +/-0.1dB, 2Hz-100KHz, -1dB
Maximum Output: 2.0V RMS
THD: <0.005%, 20Hz-20KHz, at max output
IMD: <0.007%, CCIR
S/N: >106dB, referenced to 2V RMS


Bifrost Uber:
Frequency Response: 20Hz-20KHz, +/-0.1dB, 2Hz-100KHz, -1dB
Maximum Output: 2.0V RMS
THD: <0.002%, 20Hz-20KHz, at max output
IMD: <0.002%, CCIR
S/N: >110dB, referenced to 2V RMS

Got my Bifrost today. Schiit stacks complete!

What are you feeding to the Bifrost?
