Integrated Tube Amp approx. $2,500

I second looking at the Lejonklou Boazu. I think you could find a used Leben CS-300 on or close to your budget too. They have made a few different versions over the years because of tube availability. My preference would be the Leben.

I had not considered a solid state at all since I've really enjoyed the Cornwall IV pairing with tubes, but your suggestion @helomech regarding the Yamaha 1200-2200 intrigued me enough to put everything on hold and research them. 

I walked away from a fair a bit of research impressed with their capabilities, although somewhat concerned with how they might pair with the CW IVs, especially in the top end. 

That said, I found a 1200 that was essentially new, came with a 5 year factory warranty, and the ability to return within 30 days if I didn't like the pairing for only $2,100, so I decided to do the completely unexpected and purchased one. I know that had I not, I would always be curious, so at this point all I really have to lose is time. If it doesn't work out, I return it and resume my tube journey.

Yeah if it’s risk free then no good reason not to. I had an 1100 prior to my 2100 and enjoyed it for years. It paired pretty well with Heresy IIIs I owned at the time. The X200 series Yamahas are a little less “forward” than their predecessors so hopefully that will make for good synergy with your CWs. 
 

   Just for giggles check out ESP Hi-Fi Bar in Denver ( web site ), sorry for lack of a link. They run above your budget, but they’ve paired Line Magnetic with Klipsch.  And their pics are great eye candy. Might make you consider a used unit, but they do generate a good amount of heat. My son rented the place for his office party. I’ll leave out the shameless plug for his Realestate business . 😆 Cheers, Mike B. 

@buellrider97 The bar looks fantastic, and what a great idea. Live music is always fun, but this is a fabulous twist on how to present it in a way most people have never heard it. I've long ago quit the bar scene, but if this place was local I suspect I'd be hanging out there more often than I should.

The Line Magnetic products have been on my radar for a long time, and I frequently look for good deals on used amps. They do offer a few that are within my price range, and I would have pulled the trigger, but they were all 240v, whereas I need 120v (I did find the 210ia model for $2,500, with 120v, but it was 300b. I understand they may sound better, but I shied away from it due to the cost of 300b tubes. I may revisit that decision later).

During the course of this thread one person recommended the Yamaha A-S1200, 2100, a solid state alternative. I had never considered this, so out of curiosity I researched the product. To make a long story short, I was impressed with what I read so decided to purchase one. The amp was open box, so it was $900 off sticker price, but I still get a 5 year Yamaha warranty and I can return it within 30 days for any reason. I figured why not. If it doesn't mesh with my speakers I'll resume my tube journey.
