"Smooth and Spacious" are the hallmark of R2R DACs, which are not the end game for detail mongers.....but generally incredibly enjoyable DACs that draw you into enjoying music, instead of listening to it (if that makes any sense).
I would have a more detailed conversation with Audioman58 about Denafrips DACs, as he is an importer. The recommendations for Lampizator and T+A are also solid.
I'm upgrading my DAC later this year, and the Denafrips Terminator 15th, T+A 200, and Lampizator (among others) will be on my final list. Additionally (and this is my personal opinion), the Holo Audio DACs are not at the Denafrips Terminator level.....and the Terminator 15th is really a Terminator Plus
