Impedance Mismatch: A.I. M3A, Krell KSA100

I've read opposing views elsewhere on whether there is a sound degrading impedance mismatch between the Audible Illusions M3A preamp, with an output impedance of 1.2 K and the Krell KSA100 power amp, with an input impedance of 22 K.

Something tells me that there is a definitive answer out there.

I own a KSA100 and I'm considering the M3A for use with that amp.

Thanks in advance for any first hand experience or expert advice!

I have a Modulus 3A preamp coupled with a Stratos Extreme stereo amp with a 22K input impedence. It is a match made in heaven. I am smitten with the sound and couldn't ask for any better. I would suspect your Krell amp with the 22K input impedence would be a great match as well.

Scoutdog is waaaay off base. Many people use tube preamps and solid state amps. There is no law against mixing and matching. IMHO, a krell pre and power amp makes for a very fatigueing sound. Just sayin.
