Do you have a Hi Dif Set Top Box(STB)?These allow you to receive your local HD stations. If you live in a lrge enough area--all your local stations would be in HD.--I use a 19.95 Radio Shack antenna.Next up a progressive scan dvd player. The Pan. rp56 at 199.(CC or B'st buy etc.) is quite good.--Quite an improvement over non pr.scan players.Next: How many component ins does your set have?? As you would now need 2.-- The Sonic Fr. AVM2 has comp. switching. Given what you have and what else you need I would think Krell, Lex.- Mc1, et al are over-shoot,for now.-- Keep the Krell for the fronts;use the 5 ch amp for ct and rears/bi amped if possible.It ain't mine, but there is a Sony pair; the prcessor and 5 ch amp, for 1275.(Tae N &Tae-P) in the classified now--assuming you don't need component switching-- This would get you in the game big-time.(without amputating any major parts)-- You could spend big bucks on ics and speaker wire;and gain improvements.--I would hold off till you gather all you need; then see where you are.I'm a Direct DSS person. I know they have these deals at Blockbuster etc for almost free hardware and installation; with a programming commitment.-- I have the Pan TU-HDS20; Direct, and then locals without switching inputs--1,component out for all the channels(direct,or local)Well I guess you have 'some' input?--Happy shopping.
