My bad, I meant to add what I paid for my preamp & phono amp in the post above. I bought them both when they were about 10 years old for around 25% of their original cost. I wouldn't necessarily recommend buying anything that old now unless it was completely gone through, but wouldn't hesitate buying another 10 year old unit if it was a well built one. You should be able to do that for a relatively reasonable price if you so choose.
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.
