I have a chance to get my hands on a yamaha c-70 control/preamp for a good price(less than $150, and in great shape.) My main reason is to be able to hook up my Harmon Kardon T-120 turntable to it, and to use a couple of my Marantz Ma-500 amps to drive it all. I have read some great reviews on this preamp as far as the phono hook-ups and parametric EQ. I have a chance to preview this preamp for the weekend, as it is currently owned by a friend from work.The thing I'm a bit confused about, is the best way to hook up the turntable and amps. What's the "simple" deal with this inverted preamp output? Also the direct phono inputs? Which would work best for me, or should I just try a couple different hook-ups and see which sounds best? And by the way I could also get my hands on the M-50 stereo amp, though the reviews weren't so good on that piece. I think I could get both for $200. Thanks.
