Hi Folks, I will soon be in possession of a pair of beautiful RS1a's. I realize they deserve better amplification than I am going to be able to provide right now, but until I acquire higher quality gear, here is what I have to work with. I have 2 choices on the pre. Either a Dynaco PAS-3X or a Yamaha C-85. I am leaning towards the C-85 but the more I think about it, the more I am thinking how nice tubes would be in the pre stage. I really do like the C-85's adjustable loudness control though. Tough call here. For amplification, I don't have a lot of options. On the bass towers, I plan to use my Yamaha MX-1000. Not sure what the nominal impedance of the bass towers are but the Yamaha is 260 watts @ 8ohm, 295 @ 6ohm & 330 @ 4ohm. I think that should be sufficient, right? For the mids/highs, I was thinking of using my Dynaco MK II Monoblocks. They are a solid 50 watts / channel of tube sweetness. Should make the EMIMs / EMITs dance. Have no idea what the nominal impedance of these towers are either, but I have 8 and 16 ohm taps on the Monoblocks. Would this configuration provide a pretty balanced system or is that a huge imbalance between the bass and high towers? I have always been under the impression that the high end takes much less amplification than the power-hungry low end. Thanks for any suggestions.
