Which used preamp for Halo A21, under $1,000?

Daniel825, I think you are referring to the Parasound P3, not the P5. The P5 only just came out less than a month ago. It sounds like your experience was some time ago. The P3 was discontinued.

So as I continue to hunt for the pres recommended in this thread, I've been thinking (always dangerous) about going with a tubed unit. Any thoughts on the Parasound Halo A21 with either an Audible Illusions Modulus 3A (used) or a PrimaLuna Prologue Three (new)? In both cases, I'd be sacrificing a remote, but I might be willing to do it if the sonic rewards are there.

your amp will do best with balanced preamplification.

Czarivey: Forgive me if this is a stupid question, but are there any balanced tube preamps?
