Up until recently I used a MAC 6900 integrated with my 4JR's. Sounded great and the 6900 drove the Jr's with very musical results. Auditioning in your system is really the only way to go and places like Music Direct and Audio Advisor offer 30 day in home trials on the gear they sell. You can also find 30 trials on the new Nuforce amps. I would go that route, or buy gear used that you not have to take a loss on.
