Josh,

I hope you will be as impressed as I was listening to music on the 990 in bypass or upsample mode.. the first time I had my Marantz CC4300 CDP hooked up via coax cable.. it sounded flat and muddy.

I decided to go with interconnects from IXOS and it made a very noticeible difference in sound quality. I was amazed by the openness and soundstage with the 990 in 2 ch music.

The rest of my system is
Fronts - Polk RT800i's
center - Polk CS400i (matches fronts in drivers)
surround Polk FX./300i in bi pole mode
sub is a older Adire Audio Dharman sub with a SVS 12.2 driver. It's a big box sub.. measures 22x22x22

Fronts are powered with a Adcom 5400 125wpc,
center and surrounds are powered with Marantz MA500 mono block amps. same 125wpc each

That's the HT... mixture of those Raymond interconnects, IXOS and Signal Cable IC's, front speaker wire is Cobalt Cable cables bi-wired.
