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?

It is worth while pointing out that the 1000 ASP module is capable of yielding a more/less continuous output of 500W, hence the 30.1 Amps max continuous current you have calculated, while the peak current of 45A is sustained only in short bursts, hence the seemingly discrepant figures of peak current vs max power rating. Regards, G.

It is not mentioned, though, in what I had been looking at, which was this manual for the Ref1000MkII. In any event, I think that Guido's answer essentially settles the issue. Best regards, -- Al
