Music...let it move you!
I too have an Atoll 100 which, just like Adda's unit, has had the main output caps upgraded to Clarity Caps...which really helped that unit's dynamics and slightly cold/lean presentation. It was already very lively and highly detailed (compared to a Rega and Musical Fidelity M1) and with the new caps got the extra little bit of warmth and butt behind it that it needed to be a most excellent, well rounded budget DAC. The Gungnir edges it out in terms of smoothness and musicality (makes the Atoll sound ever so slightly grainy) and has great resolution and weight but for no more than I have tied up in the Atoll vs what I paid for the Gungnir I definitely can't say the Gungnir is a better value. I'm hoping the iDSD Micro/iUSB will create a wider performance gap against the Atoll than I'm hearing from the Gungnir.
Lee Harvey had one of the Shitt DACs I think the Bitfrost with all the upgrades...and said his new iFI micro bested it pretty good. what im hearing is a wonderful performance. My CDP retailed for $1500 and the gap is huge! But of course the CDP was redbook, I'm doing DSD. If your other DACs couldnt do DSD, then the gap in performance should be huge. The nature of this DAC is warm analog sounding...that's what they where trying to get with it. Did you by any chance get any idea how many hours are in the Micro? That way you'd have some idea of what stage it's in.
