Amp suggestions for Goldenear Triton One.r speakers

Kinki Studio integrated should be on your list. I have not heard it but it’s in your price range and has power to drive those GE speakers. 

Marantz 40n ?

I'd definitely want to put some tubes on those...should help get the most of the mids and tweeter on those.  Primaluna, Rogue, VTA, Cary, Quicksilver, etc, etc, etc.

I had Cayin A100T tube integrated and and older Odyssey Stratos Extreme. Much preferred the Odyssey. The bass section although powered really seemed to take on the character of the amp. This was on the T1s. 

I'm using the STR. It's sublime. I've also used Cronus Magnum. It was ok too.

FWIW, I have T1.r’s running off a VAC Renaissance 70/70 Signature amp, it is bery good. I’d think a good tube amp (used) would be a good choice. However not knowing your room size and how loud you listen is a factor. My amp has plenty of steam. I have heard them with. Prima Luna Evo 400 integrated and it didn’t have enough toplay real loud.
