I am looking for a quality DAC.
My attention is drawn to R2R. How does it compare to other DACs?
I have two R2R DACs here, both are a little different (certainly different approaches to circuitry) yet both are wonderfully 'musical'. As a gross generalisation, R2R/Ladder DACs are the more natural sounding devices compared to the Sigma/Delta types, which have often sounded more like 'hifi' than the expression of natural and organic voices and instruments. The swing with Sigma/Delta DACs has come away from the more edge-driven, hifi-like sound to a more natural and balanced expression these days, at least in some cases. Ladder/R2R DACs need a
really good warm up time to be at their best! They also require a great deal of precision matching with all those resistors for the finest channel balance. When done right, they are mighty fine musical instruments, just look at the reviews the Denafrips DACs are garnering these days. Well deserved, I hear.
What I truly love about even the relatively 'lowly' Schiit Modi Multibit DAC is that once well warmed up, it has such a natural expression of instrument tone that last night, with a few hours on the new Mogami IC cable, I was in serious WOW land. An almost constant delighted grin on my face, many soft wows and a few omgs to boot, hearing instrument details and tone I had not heard before. The DAC is plenty good enough to show up what it can do through an even better/balanced cable than the already utterly transparent cable I had been using and also well worth pairing with the well over $400 pure silver Slinkylinks cable between DAC and pre-amp. The Willie Nelson/Winton Marsalis album, Two Men With The Blues came over as the very finest I'd ever heard it. Such natural (that word again) realism of the instruments, stage presence and Willie's husky voice pushed well forward remained husky without the edge it can often have. I was in awe. So the new cable let me hear more of what that DAC is capable of, the cable is just so
'quiet', ie, like the #2893 cable I use for my headphones it seems to have less or no interference with the musical signal, allowing me to hear more of the DAC's abilities to just play music. I want more of that cable in my other systems!
Sorry if I appeared to go slightly off track, but not really, I can now hear more of what the little Schiit is capable of. The DAC in my QP1R is a Sigma/Delta type with Class A circuitry, it too sounds damn fine, very enjoyable but just a tad more 'hifi', no bad thing in this case, though I have heard many S/D DACs that are just edge driven ultra-clarity but eventually quite tiring to listen to.
Best thing is to just listen for yourself, you might end up with both types.
