Got my first listen to a Rogue Sphinx amp this weekend.
Pioneer Elite CD/SACD/DVD player
Tara RSC Prime Speaker wire
Monster Reference interconnect
Montana SPX Loud Speakers
Un treated room, carpet floor, drywall walls and ceiling, raised subfloor.
Impressions. Nice open sound. Very refined for the size & price. Sweet top end tight well controlled bass. I only got to listen to a hand full of songs as our families were together for dinner and a movie. From the cuts I heard, I was impressed. Female vocal was amazing, very natural with the proper size and weight. Nice ambiance from the open sounding top end and of course LOTS of power on tap. No "digital" edge that I could notice. I would say the $900. Pioneer CD player was the weak link in this system and it's very good for the money too.
A little plain looking, but cool running and nice feature set. Good enough to make me want to try a model with balanced input at home. Nice implementation of the Hypex tech.
