@williewonka, thanks for the recommendation on Zavfino. Will definitely check it out.
@ghdprentice, you are correct that I'm actually pretty happy with my current system. In fact I recently upgraded a couple of IC and they have made a huge difference. Do you remember your participation in this thread that I started a couple of months ago?

Also, thanks to your suggestion on tube amps on that thread, I had decided to do some research, and just placed an order on a Cary SLP-05 tube preamp at a pretty good sales price. Now I can't wait to listen to it.
@mike_in_nc, thanks for your thoughtful comment. Like I mentioned in my previous post, upgrading power cords in my system does not seem to make much of a sound improvement so far. That's why I was curious if upgrading the power cord of my line conditioner will make a difference.
