My "25k Dream System" would be basically what I already have, with the addition of the new JVC D-ILA PJ, a new 84" Carada Criterion in BW & a few GIK and RealTraps panels. If it would squeak in under budget I'd upgrade to a Meridian G68 and a 2CH amp to run the rears (my current amp is a 3CH Butler).
Now, if someone was
giving me a "gear certificate" for $25,000 with the stipulation that I couldn't get any cash back, then I'd keep my current rig and add a 3 chip DLP.
