Our auditory memories are notoriously bad. I did swap back in the old card because I was curious and had a little bit of "FOMO" in regards to the old midrange. What I found was that it was an across-the-board downgrade. The midrange on the new card is just as good—rich, full. organic, etc., it just doesn't stand out as much because the bass and treble are brought more in line with it. The only downside I would say comparitively is if you are looking for a more relaxed listen. The new card defintely shoves more details in your face.

Also, if burn-in is a thing, consider that you are comparing a card with potentially 100s of hours on it against a brand-new one.

It's good to hear a more positive view Frisky, buuuut, is it possible that in the time you took to swap things out and reboot, you also might be prone to the auditory memory problem?
I'm hoping you are right though. Although I don't trust my auditory recall full on, there are things that make sense to me, like the visceral reaction to brightness that seems a bit grating which I never had in hundreds of hours of listening to the BF2, or scrambling around readjusting my sub because I can't seem to fill the gap I'm hearing in the bass. It's a bit like pitch recognition if you're a musician, where we may not all have perfect pitch, but we still know when a string on the guitar has strayed too far off and makes us scrunch up our shoulders a bit!
Still, not disagreeing one bit with what you're hearing, and I do believe in burn in for sure, and hope things will settle down.

Regarding Bifrost 2/64 and the sample rate glitches noted in some systems: we have new firmware to address it.

If I'm Not having any issues with 2/64 upgrade, should I just leave well enough alone and NOT install the latest FW ( Bifrost 2 C0094, D0109)?

 

[Friskyseal]

I installed the new firmware on my Bifrost 2 and the problem is fixed. I can switch between 48khz and 96khz without issue. Well done, Schiit.

Thank you! Anything you can allude to as to what the issue was?

I can happily report the new firmware did indeed corrected the distortions when changing from 16/44 to 24/96. I was so frustrated that I was only listening to cds from an audiolab 6000 transport just to enjoy the new sound.

Thanks!

They reported that this code was found inserted by a topping engineer

if(sampleRate.isChanged() && sampleRate.equals(96000)) {
causeDistortion();
}

Either/or. It can't hurt to have the latest firmware, though.

I'm actually not sure. Dave noticed a glitch at 192K with some players (oddly enough, not really much reported at 192). That glitch caused the rate to change to 24K/12K, which of course ain't great. He was complaining about eye diagrams and such, which leads me to believe it was a timing issue on the DAC8812, but not the original AD5781.

Mike must have put that one in!

Haha, I love you guys.

I think the 2/64 is a home run and knew you'd have a quick fix for the issue, which I fortunately never had.

There was a discussion earlier in this thread as to whether there is a reconstruction/smoothing filter applied when in NOS mode. Doesn't seem too trade-secrety, so I wonder if you can settle our curiosity?

 

[erwinjaquez]

What do people see on Roon when using the Bifrost 2/64 in NOS mode?

Eg for Qobuz source through Jotunheim MB DAC/Amp on 24/44.1...

Argh, I should run some APx tests on the NOS. Short answer: NOS is NOS. Stairstep heaven. Please use the upsampler of your choice, or enjoy real NOS, no interpolation, no reconstruction, no brickwall analog filter.
