High Current SS amps with input impedance = 200K


I'm looking to identify amps like this that would match optimally to an Audio Research sp16 tube pre-amp with output impedance of ~ 20K?

NEwbee, you may be right.

Here are the specs from the arc site:

OUTPUT IMPEDANCE: 260 ohms Single Ended main; 20K ohms minimum load and 1000 pF maximum capacitance. Outputs (3): 2 main, 1 record (Single Ended RCA connectors).

I'm not sure how to interpret this though if anybody can clarify for certain.

Is 260 ohms the pre-amp output impedance and 20K OHMS the minimum recommended amp input impedance maybe?

BTW, I have seen at least 1 ARC SS amps out there have 150K ohm input impedance specifications.

Well, that's very different then.

ARC's specs are the most detailed I've seen so far then in this regard, and my original question is a moot issue then I suppose..
