An installer friend dropped by today with a nice (borrowed, unless I buy) present. An older Audiosource 2 channel amp, 80wpc/2. I was skeptical that it would improve the R50 fronts. I'm not any longer. It is very nuetral sounding, cut some slight sibulance I was hearing, better midrange and more snap and detail for the highs.
I got a jump when I went from the Onkyo to HK and now another. My surrounds also improved. It's not night and day, but it's nice to hear. I was getting some fatigue with certain sources, this seems to have cured it.
I've been wanting to experience what you guys were talking about going with separates. Just didn't think it would apply to these speakers, which sounded pretty good in my modest room, but now better. I'm kinda getting the itch to move up the foodchain.
