I need to set up a preamp and a distribution power amplifier: given the choices between

1. Preamp RC 1082 with power amp RMB-1076
2. Preamp RX 1052 with power amp RMB-1076

with option will give me more better & clean sound ? All above model are Rotel. I need to use 2 (could be 3) pair of speakers in different locations simultaneously.
Speakers: monitor audio GS10. Appreciate for all advices.
