Thanks for the input Andredoan. I'm also using NHT's right now - the ST4 towers. They are powered by an Aragon 4004 MKII with an Outlaw 990 preamp. Very clean sound with a lot of power but I'm looking for a 5 channel amp as I move into my new apartment where space will be more limited.
It also doesn't hurt that the TGA 5200 is much lighter and would be easier to move!
