I would suggest nothing less than a CJ Premier 17ls tubed pre-amp. Your adcom is far below your amp and cd player and is without a doubt the weakest link in your system. I would not even consider modding it.
Get a top CJ ,or ARC Depending on your musical style the CJ will be lush like the amp but the ARC is a little more detailed . depending on your preference an audio research Ref one is a steal used at under $ 3800.00
Why not Adcom in passive mode? Shouldn't passive mode be 'without' the sonic character, therefore you would be listening only your amp? I am curious myself as i am shopping for the new pre-amp and Adcom is on my list.
