NAD Processor Break in period

Well thats what I was thinking as well. Thanks for the second opinion.

Sorry, I can't offer any more advice. If it is significantly different than it was before the repair, and you have verified that it is not a configuration issue, it seems like you may have a defect. If the repair was performed by a professional, I would take it back.

Yes, I have tried a lot of different things. I took my brothers 753 home to do a direct comparision and the 753's bass is much better, everything set the same? I've tried adjusting everything I can and the bass still sounds thin to me. Any suggestions? Is there anything I can have looked at to see if there is a problem or is this just the way it is going to be with this reciever?

Doesn't sound like anything that break-in would resolve. I'm guessing that you have lost the previous configuration that was set up in your processor before the processor board was changed. Have you gone through the setup menu yet and re-calibrated everything?
