Okay, if you've got a budget of $2000, your made in USA options are limited for a pre-pro and a 5 or 7 channel amp.
Outlaw carried a Marantz receiver that I believe could be set up as a pre-pro, and with one of their amps (7125) in a package deal you would have been fine, but they only seem to have the $2500 Marantz pre-pro now, too bad.
But you could still get the 7125 for $1000(or ask for a B stock for less) and get a mid level receiver with pre outs and room correction for $6-700 or so, and you would be quite happy. Emotiva would be another budget option for amps, but the Made in China thing crops up again, but to be honest with you, getting truly made in the USA gear with USA components is impossible now. That ship sailed some time ago.
Since you had a receiver before, I would also suggest looking there again, for under $2000 you could get a near top of the line Marantz or Denon, and they would match well with your somewhat brighter sounding speakers.
