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?

Just a WAG - I didn't bother to research it, I'll leave that up to you. :-)

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.
