Hi, I'm looking to change my speakers (rega R5's) to either rega RS5's or ProAc130's. My current set up is a Rega saturn - Nait 5i v2 - chord chameleon silver plus - rega rs42 and a chord power lead. I like the r5's but when I crank them up a bit the music sounds a bit light? I have no dealers near by to audition so any thoughts on the ProAc's or could it be the amp? Thanks
