Do I have to buy all new CDs?

BLbloom, I think you probably addressed the problem most accurately. I think my amp and speakers mate well together (the Sunfire was recommended when I contacted Martin Logan). But I have another thread that sought suggestions for a matching tube pre-amp. My adcom-gfp 565 is used in bypass to avoid degradation, but after all I've read on tubes that will be my next purchase. The second weak link is using a Sony 7700 for a Cd player. I'm new at this and working on a budget, so the sony offered the best of both worlds at the time (Quality and Affordability). My room is also very limiting , but I cannot change that. And I am not willing to change interconnects when I change genres of CDs (That seems excessive, to me.) Most of my CDs are more than 5 years old, and mostly rock. But lately I have been listening mostly to acoustics (James Taylor and Eric Clapton.) Hopefully the tube pre-amp will work the magic that everyone seems to say it will, and as for a dedicated CD player, I'm saving my pennies. Thanks for your inputs!

kubuli...I'm afraid that is true to a degree. It sounds like we listen to the same types of music. I fell in love with the Martin Logans and didn't heed a lot of warnings about their difficulty in placement and inability to rock and roll. I think that is largely overblown. What they are is incredibly transparent, and a lot of mainstream music isn't recorded as well as classical and jazz recordings. If you are looking to upgrade I might shy away from the ESLs if you listen primarily to rock and blues, unless you have the time and money to invest in all of your components.
