I started a thread about this, but didn't get any real answers: I'm looking for a more aggressive DAC than the Mojo that costs $500 or less. The Modi Multibit is what I'd go for if I can't find a better alternative. Both MMB units I owned made mysterious crackling/popping noises that the manufacturer could not replicate. Back then I only used USB, but perhaps with TOSLINK, it wouldn't do that anymore. I think the Mojo is more refined, but its smoothness is becoming a problem for me with more energetic music. The MMB is affordable enough that I could compare it directly to the Mojo without having to get rid of anything beforehand. (I used to have a 2Qute, MMB, and Fulla 2 at the same time.) Just wanted to check here to see if anyone knew of anything else I should check out.
If I use another DAC, I'd just use a passive preamp for the volume control. I have a Schiit SYS, but it makes scratching noises, so I'd like to try the JDS Labs OL Switcher.
