Congrats Manish.....
Its an amazing amp, plenty powerful and dynamic for those speakers, I'm sure its made a nice improvement on your system....
Looks like a good next step would be to upgrade that Yamaha receiver, I assume your looking at Pre-Amps down the line...
I was at a buddies house and he has a Yamaha receiver and implemented a HT bypass with a Parasound 2100 just for 2 channel listening... sitting down and A/B at the push of a button revealed huge differences in the width and depth of the soundstage.... I would have never thought that drastic of a difference would happen.... The Parsound has some nice DAC's which really opened up the sound.
Today I'm headed to a meet in chicago to listen to Mark Seatons products, should be a fun day...
