Ok I've had 3 of those amps! I found the Aragon MkI pretty lifeless on a pair of a/d/s 1290 towers. The Rogue is a nice tube amp for the money; somewhat forward for tubes and decent bass. Very nice midrange, highs are not as refined. The PS HCA2 needs breaking in and benefits from being left on (it runs very cool). Mine sounded terrible for the first few weeks, now sounds great, dynamic and lots of bass running with Tyler Ref monitors and AES DJH pre, Anthem CD1 player.
I can't say how it would sound in your system but the PS is staying in mine for a while.
