He could build a pretty respectable system with:
-Outlaw 1050 A/V receiver
-Axiom speakers(80s up front, M3s surround, center, sub)
-Pioneer DVD player(as transport into Outlaw)
-Apogee Wyde Eye digital cable
-ZuCable interconnects/cable
The entire system would cost around $2500 and be great for music or movies.
If he's got some spare cash:
-Linn CD12
-Ayre DVD player
-Boulder pre/pro
-Halcro amps
-5 or 7 Talon Khorus Xs w/ 2 Roc subs
-Nordost Valhalla cables all around
-Crestron remote to tie it all together and make it easy
Of course there are a few options in between. Best of luck.
