What kind of sounds are you looking from your 2nd system? What is your budget? The GPA rack is as good as it gets but why would you build a system around a rack? The GPA rack would improve ANYTHING you put on it.
Wow, this is like that thread a couple of days ago. What speakers to buy for Cardas speaker wire.
How about the same stuff you have in your current system.
I am missing something here? Is there something special about the Grand Prix rack? The only concern I see would be the size of the equipment if the shelves of the Grand Prix are not adjustable, which it looks like they are not.
just a thought.......without knowing your budget though, but based on the money spent on grand Prix stand...
how about going with all ARC components but a bit lower profile than what's in your main system(since ARC is what's there, I assume you like it).
ARC LS-25MkI or MkII,
ARC VT100MkII or MkIII
season it with the cables of your choice
anything should sound good on that stand you bought
