Pl advise on Amp for listening to AOR on Klipsch RF7 Mk II via a custom built R2R NOS DAC

Actually in the radio biz, it was called Album Oriented Rock because one track could be 23 minutes such as Pink Floyd Echoes.

I don't want to criticize your speaker choice but have you seen this video?

I was going to suggest crossover upgrades first.

Oh! Did not know that. As I don't have tuned ears, it sounded great to me when paired with a Krell and a Concept 16.5 separately. Perhaps because I did not have much exposure to listening to different speakers side by side. By the way, how are Paradigm Signature S8?
