Umm, don't forget Lexicon and Cary.
(Also, ATI doesn't just "make" Theta. They own the brand. Also, B&K now. And a few others whose names escape me.)
Given that extra information, it should be clear that my earlier post was in jest.
That said, if one wants a well-designed, well-made, sonically transparent, high powered multichannel amp with top-tier after-sales support, ATI is a very good choice. If one wants to sink money into a "high end" faceplate, one can do that while still getting...most* of the other advantages of the ATI, one can do that with a Levinson, Cary, Lexicon, etc. amp.
To the OP, I use an ATI AT2007 to drive Pioneer EX front speakers, KEF R800ds side-surrounds, and KEF Q100 rear surrounds. It does not do the job any better than my old Sherwood Newcastle A-965 did, but it's a little shorter and I can now keep the back panel on my stereo cabinet closed. Sonically, it does nothing except for amplify the signal. Basically a perfect amp, with no perceptible self-noise and tons of headroom. But if having a so-called "classified as high end" amp is important to you, then other people probably aren't going to recognize the pedigree of ATI as much as some other brands that are more regularly sold by expensive audio parts dealers. You won't end up with worse sound if you choose a different brand. The main real-world performance difference between them boils down to the faceplate you want to look at.
*I write "most of the other advantages" because after-sales support, warranty policies, etc. may be inferior with a "high end" brand amp compared to an ATI amp. Best to read the fine print.
