gonna post it on HF.

tl. dr. 

That was me. I sent my first Mjolnir back to Schiit. The diagnoses here of a potential DC offset issue prompted me to take Jason up on a full refund.

I ended up paying the higher asking price for a second Mjolnir from Schiit's Australian distributor. I've had it a week and was initially convinced the popping and crackle had gone with the first unit. Nope. Still there.

So two possibilities. The noise is symptomatic of "dirty power" (though other amps I've owned haven't exhibited this problem), or I've received another unit (from the same batch as the first) with the same fault.

Not sure what to do now. I think I need to invest in a DMM and see if can isolate this issue. I'm a huge noob in this area. Hopefully you guys can advise.


edit: other than that, I agree with purrin's incredibly succinct assessment. This amp should be added to the prestigious Pirate's Booty list.

Yeah I had a bad run with the Bifrost. The first unit I received was a non USB 110V when I had ordered the USB 230V version. Replacement arrived missing the input selector button, had misaligned LEDs and appeared like a rush job on the production line. Third unit would lose sync, causing the Bifrost itself to click like it was communicating in Morse Code. The third unit was diagnosed as requiring a board replacement by Schiit's Australian distributor. In the end they sent me a brand new replacement. The thing now works as intended. No complaints.

My issues with Schiit don't point to a single cause. It's absurd what I've gone through though.
