Cracking amp... bested a Naim XS3 and Lyngdorf comfortably, as it should at the price. Pairs great with the Neat Petites and some Dali Opticons I had. The latter needed a bit of kick up the backside and the Rega happily delivered. Tasteful dollop of warmth, grip and proper foot tapping stuff.
The only thing it didn't pair perfectly well with was Dynaudio Heritage Specials. But they are incredibly revealing/fussy to pair with, the Aethos was a bit too punchy for that set-up.
It's much heftier than it looks and it runs quite warm. Second fav amp I've owned.
(I'm moving my Aethos on this week, I may list it on here - never sold on PFM before so need to figure out what's what)
