Threshold S300 power amp.

I can help. My email is jpainter236@hotmail.com

your email server will not let me email you.

Does anyone know the input impedance of this amplifier?

Thank you for your consideration.

Sir,
Thank you so much. I finally figured out why my email program rejected your and many other emails. My security program (Zone Alarm) was set improperly. I've fixed the problem. Thank you for your efforts to send me a copy of the manual for this amplifier.

By the way, would you share what your system consists of and what cables and line conditioner you use? Thank you very much for all your troubles sir.

Bob

I take it you've received the manual, if not, I can scan mine and mail it to you.
As for your question about the system: preamp is an Audio Research LS-2, loudspeakers are Apogee Centaur Major's, cables are German W&M. Sources are a Goldmund TT and Audio Alchemy cd-transport and Northstar Design DAC. No line conitioner. Hope that helps.
