guess i'm late to the party here, but i was waiting for someone to get back to me on the availability of the Perreaux SXH2...
Perreaux have a new U.S. distributor, finally...they disappeared there for a bit, twice...
anywhow, i used to own a SXH1 and used it, interestingly enough, with Grado HP-2...the pairing of an exceedingly neutral (if such a term can exist) can with a warmish amp worked better than i honestly thought it would...
the Perreaux, to me, gave the sense of listening directly to the source then being sucker punched
...sort of warm, but without muddying the details...
back when the SXH1 first hit the scene, i
believe it was SovKiller who was using it with higher end (note: large cup) Sony cans yielding positive results...
those Sonys
arguably suffered from some of the ill effects the Denons
arguably have...
the newer, allegedly improved Perreaux sometimes pops up in the For Sale forum in the OP's price range...at this time, i'm unsure of the price their new distributor is asking...
