I agree with Rogerroger, I have had an Audible Illusions M3A in my system for the last 4 years and I have absolutely no desire to replace it. It is a wonderful sounding preamp and has a very neutral sound, not tubey. I have used it with a Bryston 4B NRB amp with great results.
Best Preamp for under $1750.00
Seeking recommendations for a preamp in the $750 to $1750 range. Balance of system consists of Aerial 8's, Bryston 7B's, and CAL CL-15. Room acoustics and speakers would favour lean over lush; I'm looking for something musical without being on the "warm" side. Music preferences include acoustic, jazz, and rock. Will re-cable according to final selections
