Integrated for Cornwall IV

That’s good to hear. If I go ss that’s the main one I’m looking at. 

Coincidentally, I just put a post about how my Forte IVs sound amazing with my Luxman 505Uxii and 507Z however, the 590axII (I think that’s the right model number) is class A and I bet it would be amazing with your Klipsch. The tone controls are also amazing on these integrated, so would allow you a little tweaking if necessary, or you can disable and go line straight.

I had a Decware integrated, 6 watt on the Forte IVs, but the Luxman blew it away

Really depends on what sound characteristics you’re looking for.

I’m interested in the Cornwall IV’s and have been researching them. My present system has both a class A amp (Pass XA25) and Quicksilver Mono 60 tube amps (which can run KT77s, about 25w each).

After doing a bunch of research on these very sensitive speakers, I see a lot of evidence that lower watt amps are the most musical match with these speakers. We’re talking less than 30 wpc. So, First Watt, Decware, 300b amps, that kind of thing. Such amps should be able to play all kinds of music, easily, and likely provide the best pairing with the Cornwalls. Again, this is based on my research.

If I go ahead and get the Cornwalls, I’ll be trying them with amps from 3 watts to 15 watts or so.

Just my two cents.

Sugden should be quite good. Also, I'm told by someone whose tastes line up with mine that an Accuphase E-280 is like peanut butter and chocolate/peas and carrots, etc. etc., with the Cornwall's.
