MCB all the way for me, but it doesn't hurt to flash to the newest firmware. It does not change the character of the music -- with thew OG card it just makes NOS available for experimenting.
Is it just me, but i already using USB and COAX in BF2.. USB connected to macbook air + music + lossless... and raspberry + digipro plus + volumio + linear power supply to raspberry... no contest.. Rasp sound the best connect using COAX... the background so dark... music so detail and texture...
i am using Reisong A-10 tube amplifier with speaker out converted to XLR output + Sennheiser HD800... yes u can heard the difference....

I used Allo Digione with Raspberry Pi 4.0, coax output from Digione to BF2 before, the sound is noticeable better than RP USB output to BF2, better in detail, layers, 3D feeling , BF2 Unison is nice, but still distance from good.

Good to know somebody else agree with me... for everyone else that using USB, try to use proper COAX/OPTIC/SPDIF sources... you will be suprise.... lets keep the USB just for computer only, haha...
Is it common practice to leave the bifrost 2/64 running at all times? I've been turning it off at the end of each day, but know the yggy is best left turned on for prolonged periods.

I feed bifrost 2 OG with pi2aes using a BNC to coax cable. Definitely better IMO compared to unison USB out of pi2aes or anything else I've tried USB. Much more tactile sound, much blacker background and more detail/separation. Unison is good but it's tubey, bloomier and more cloudy sounding. I guess depending on the amp and DAC either could fit but I've never found a situation where I preferred unison USB. It's the still the best USB implementation hands down though.

The AD D/A chips need a fairly long time to thermally stabilize. They are designed for continously being powered on. Things like MRI scanners use them. So yes, leave it on.
SPDIF and Unison USB should be sonically similar if not the same. Mike Moffat has stated AES/EBU is the best in his opinion, but the Unison is pretty equal to him.
That being said, i can't hear a difference between the coax to my Yggy or Unison. Nor could I hear a difference with the Bifrost 2/64 in a similar setup.

My experience is different, streamer is raspberry pi 4B, USB output to DDC or Bifrost 2 directly.
SPDIF from DDC to Bifrost 2, sound quality is better than raspberry pi USB to Bifrost 2. The quality of SPDIF signal is also important. Unison has separated the power and ground from USB, there has reclocker inside Unison, how good is Unison did it's affect the sound quality.
Unison USB™ is USB, Elevated
Bifrost 2/64 features Unison USB, our own USB input based on a general-purpose PIC32 microprocessor, using precision local clocks and complete electromagnetic and electrostatic isolation. No more off-the-shelf USB—this unique, UAC2-compliant input provides the highest performance and lowest power draw of any USB input we’ve offered to date.
I think the « USB Unison » thing makes USB the best choice. Maybe others will comment, but that is what I understood.

Unison and other modern USB implementations have always sounded better than aes/spdif to me, with the caveat that on a raspberry pi 4 (I wouldn't bother with the lower models for audio), I would go with a good quality linear power supply and lots of tweaks, like turning off led's, bluetooth, and wifi, and making sure I'm using alsa with no mixer.
