jl35, soliciting recommendations for picking a preamp in particular is always a tricky proposition since it interacts with the source on one end and the power amplifier on the other end. This is even with discounting all the cabling in between. I can share my experience since I not only have the same preamp but also have the same source - Bluesound Node2. In my set up I have one of the pre-outs from the preamp feeding a Vincent SP-331 amplifier and the other pre-out pair feeding a pair of McIntosh MC2200. The speakers pairs - completely different brands, are in two adjacent rooms, family room and a sort of formal living room. If I were to characterize the differences in sound quality between the two rooms, I’d say the sound from the room using the Vincent is more analytical and has slightly more detail than the room fed by the McIntosh amps. Even with switching the speaker connections from one room to the other, which I do occasionally just for variety, the character of the sound stays generally the same. I don’t know your amps but at the risk of generalization, most class D amps tend to benefit from a tube front end to sort of smooth the edges. The friend that I borrowed the CJ from has a pair of class D amps that he assembled himself - I think they Hypex Ncore, and the CJ preamp sounds a whole lot better in his system than it did in mine. Hope this helped.
