Thank you all for the responses. Yes, I have a sub but for the hell of it I tried lowering the xover point to 40hz and setting the sub to off, it sounds the same. I have also tried turning on the bypass but all it seems to do is lower the volume and I have raise the volume more to hear the same level.

The sound just doesn't seem full and doesnt give the oomph that my speakers need. The mids and highs are nice and clear but no bass.

In regards to the other suggestion about getting another pre/pre, I actually thought about it but I'm past the 30 day return and I'm debating if I want to go through the hassle of selling this unit. I figured I will just have to keep tinkering with it to see if I can make it work.

The other suggestion about hooking up the other preamp sounds complicated for me..hehe. Do they make switch boxes for audio inputs? Maybe I can put a switch between the amp and both preamps??

Thanks again
