Just exactly how much does he want to spend on some gnarly stuff? Rich is a somewhat relative term.

If he's really rich, I can suggest some really cool speakers that will set him back 100 grand. And a turntable that will approach that figure as well. Or, perhaps an amplifier that runs about half that?

If he's just kinda rich, the Anthony Gallo stuff will bring out a few oohs and ahhhs. That will set him back around 3500 bucks.

If he's somewhere between the two, the world is his oyster when it comes to audio gear.
