The Treo’s are really nice speakers, one of the few I would consider replacing my Magnepans with (previously have owned 3A Sigs). As you are looking at integrated amps, and I don’t keep track of them, I won’t make a specific suggestion. That said, I will note the Treo’s are pretty inefficient at 82.5db/w, but an easy load not going below 5.5 ohms and no high phase angles. As such, you should target integrated amps with at least 100 watts per channel (100 watts will get you about 97db before clipping; if you listen at loud levels, more would be necessary).
As you already have PS Audio, have you considered the S300 amp? You could combine it with a Schiit Freya S preamp for $2,200 for a very transparent combination that takes up no more room than an integrated and runs cool.
