Wanting to try a tube amp.

Looking at  an ARC Ref 110 to go with my Ls28se. Used is fine with me want to keep it under 4k. I only stream thru a node 2i and Audio Mirror iii se. Speakers are GE Triton Refs. Any other thoughts for me? Room is 14 wide 24 deep 8 high. Listen to mainly Pink Floyd, ELP,  and rock in general. Don't play loud, about 75db. I'm already deaf and have a pretty decent noise floor in my head to compete with. Thanks.
