Cio09,
Nice setup, I also run the CEC TL-51X and although the stock unit is no slouch, I wanted to take it to the next level.
So, I had it modded to the max by RAM, $2,000.00 after everything was said and done, but oh what difference it made. I've run mine for a couple of years now and the sound still blows me away.
I also noticed you're using Creative Concepts Pigtails. I also find these to be great little devices.
Another similar tweak, you may want to try, which I couldn't live without, is Walker Audio's High Definition Links.
