Audible Illusions M3B with Aragon amp?

It appears your preamp output impedance is on the high side at 1.2 Kohm but I would be more concerned about the preamp gain.  You better look for an amp with input gain control or better still go with some other preamp if it is not too late.

Thanks for your reply. It is too late, but that’s okay, as I’m looking forward to trying the M3B. I’ll try it with my current amp, and if I don’t like it I’ll sell the Aragon and look for something else. Maybe a Parasound A21 which has higher impedance as well as gain controls.

Good luck if your dealing with Al, good guy but just can't get right on delivery times. Sent him a M3A for repair, wound up trading it in on a NOT YET BUILT M3B, promised in 6 weeks delivered in 15 months with delayes every 2 weeks, thought I would go nuts. Like I say, really loved the preamps and used them in my system for 15 years, go ahead and get you a set of Rothwell in line attenuaters to offset the gain, I use them with no ill affect.
