You know Lenny, I am starting to LIKE you. HA!!!
Even as fully tweaked as I am, there's always more. You've gotta set your limit at some point. This year, my only change has been to Wireworld silver video component/RGB and copper plated silver S-Video cabling, but otherwise I am being stagnant and enjoying what I have (AMAZING!).
But I could put new cryogenic AC outlets, put Power Ports in my PS Audio Power Plants, put high end copper cabling in my walls, upgrade to the new Aerial 20T or 30T speakers, upgrade to Theta Citadel amplifiers, the list never stops. We MUST at some point be very happy with what we have and set our limits with what we can spend. Oh, I forgot, how about the "X" modded 9" CRT from Chris Stephens and top line Teranex processor.
And heck, as a reviewer, I generally can get dealer cost - but I gotta have news for you, dealer cost is still - $$$$$$$$$$$$$$.
So don't feel bad Lenny. We're all in your shoes! One thing the Tweaks forum allows is to give you lotsa ideas, some DIY, and if you can control your spending habits, maybe improve your audio and video but not spend too much in the process. Woops! I flunked that test. I think I TRIPPed over the LITE! Oh well!
