For the past couple of years, I've been using my original Schiit Bifrost DAC as my desktop PC sound card, instead of the old Sound Blaster Titanium. The Bifrost became available when the Oppo 205 moved into my main system. It feeds a Magni 3 with HD 600 headphones. This has been a very satisfactory combination, playing mostly high res files through JRiver, which does conversion of DSD files as needed. A few days ago, Windows started to have trouble recognizing the Bifrost, so I think that the USB board is failing. I could replace it for $200, but I think that I would be better off with a new device. I'm back to the Sound Blaster, which is worse than I remembered. I need to keep the price down on my replacement equipment - definitely under $500, preferably a lot less. This is not critical listening stuff, just part-time entertainment. Schiit has multiple options, none of which do DSD, which isn't critical thanks to JRiver. Unfortunately, they have different combinations of features, such as Unison USB, different DAC chips, and Micro USB. I can't see a clear winner. Availability also differs. Modi 3+ - $99 (AK4490 chip) Modi Multibit - $249 (AD5547 chip, no Unison USB) Maximus - $199 (AK4493 chip, Micro USB) Anybody have an opinion on which option would be best for my purposes? Or is there another brand that I should be considering? I see a lot of bad feedback on iFi quality, and everything else approaches my price limit. Thanks!
