used power amp under 1500

+1 on Coda.

I'd add Belles and Hegel to your search list. Those were my 3 finalists the last time that I was in your shoes. Went with the Coda and I am thrilled with it.

I'm very pleased with the sound. I also have an old Yamaha M80 "super" amp that I switch with. Can't tell any difference. These a driving a pair of KEF R3 Metas. They  are augmented with a pair of HSU subs,

thank you @llg98ljk 

@mitchagain I love Belles and value Hegel too! Belles is hard to find, Hegel is on the pricier side. 

@llg98ljk It's probably a great value. I will check the return policy

@parkergetdean , I totally agree with you and that was also my experience when I was shopping for an amp upgrade. Fortunately, my patience paid off and I pounced when the opportunity presented itself.

@mitchagain 

I tried the H190 in my system. It was good but not the sound I was looking for. Belles - is the white whale for me. Not too far out from my budget but never shows up locally.
