If you had 6K to build a system with used gear?

Hi there I was curious to see what people would put together for around 5K give or take $500

I put together a second system based around tubes and was curious to see some other Ideas from folks.

Mccormack RLD-1 CD (My buddys player but I'm putting it here)
VTL Ultimate Preamp
VTL ST-150 Amp
Velodyne SMS-1 Equalizer
Adcom GFA-5500 Amp (For the Subwoofers)
Custom Speakers that are overbuilt with focal woofers, accuton tweeters in a MTM and over $1200 in crossovers, with matching 12" Compund subwoofers in 4 Cu. Ft. or so 1" MDF Boxes that were lovingly and masterfully built. (Score of a lifetime!)

Its always cool to see what people can do on a budget and I feel past 6 grand diminishing returns come quick
