Yes! I would listen to your friend and get the C30, it was only made for a couple years 1985-1987 and has a auto turn on socket plug for your turntable and has better phono signal to noise ratio (90db) then the C32 (80db) which was sold from 1977-1981. The C32 has a lot of stuff crammed into it, like a 3rd tape loop and a compander/compressor circuit. The C30 seems to be a more minimalist design geared toward vinyl playback.
P.S. C28 was sold from 1970-1978 and is not in the same league as the C30.
