Phono preamp question
I'm slowly trying to upgrade my vinyl system to something that could be considered moderately decent, not necessarily high end. I have an older full feature preamp and am thinking in getting a separate phono preamp. I'm assuming the phono preamp would need to be connected to one of the line inputs. Would my preamp be the weak link if I get a good phono preamp to use with my existing preamp? Can a phono preamp be connected directly to the amplifier? FWIW, the preamp is an Adcom GTP-750. Thanks.
