OK, first post. Here goes. I'm a newbie here and what I want to know is the best way to increase the power going to my speakers yet retain a vintage sound. To wit: I am running a turntable setup (JVC YQL-3 and QL-7) into a Marantz 2270 that is feeding stacked EPI M250s (four speakers -- that's 16 drivers in all). I suspect I need more power for the EPI's. They sound pretty great now but I wonder what about 100 watts-plus per speaker would do for them. But I don't want to blow them out either as they aren't fused. So, do I need to try to stay all-vintage and upgrade to a Marantz 2325, 2385, or 250 amp etc? to maintain the sound or would it be easier (and just as sonically pleasing) to go with a new amp like an Emotiva XPA-5 and use the 2270 as the pre amp? Suggestions anyone? thanks much!
