A local dealer featured the persona line a couple years and my favorite pairing was the Pathos Logos mk2. I listened to the Anthem str integrated, STR amp/pre, a 60 watt lumin int. peachtree, and a couple others I can't think of. For those that think all amps sound the same, they've never listened thru the persona's!!!
I ended buying the 7f after a year or so because the pathos gave them the natural tone and lifelike soundstage the other gear would present in different ways, cool, but different.
My second choice was the little Lumin integrated class d like 60 total class d watts that stayed out of the way. I never turned the volume up with that one. The STR separates were very good, but made the images within the soundstage miniature?
Maybe placement also, idk. Pathos was affordable, around $5k BNIB, tube pre and 100 wpc a/b amp.
