I'm going to recommend something a little different, if you call or email Al at space tech labs and tell him exactly what kind of sound you are trying to achieve he will get right back to you and have a recommendation. Most of his preamps are balanced input and output.
Preamp for Parasound and B&W803d2
I have a set of B&W 803d2 now paired with 2 Parasound JC1 mono blocks, I am trying to find a matching balanced preamp which is more on the softer side.
I was thinking about Mcintosh C220 (tube) or Pass Lab X1 or maybe a PS Audio BHK hybrid.
I would be interested in your opinions on the preamps. Thank you.
