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.

dekay, by the way, I have no doubt my current preamp has a much better phono stage than that $40 piece of crap you recommended. But thanks for taking the time.

Sorry, a correction its a GFP-565. I don't know why I was thinking 750.

kalili,

That Walt Yung-designed preamp/phono stage was exalted in its day (not to imply that is it not still excellent at that price point) and should be ample to give fine sonic results with your current TT/cartridge.

Should the upgrade bug prove irresistible, I submit that you first try upgrades to the cartridge (within the gain and loading parameters of the GFP-565's phono section and careful compliance matching with your tonearm's effective mass).

Kalali:

My rec was based upon the preamplifer you first listed (GTP-750) which is a medicre sounding HT preamp from the turn of the century.

Now you list your preamp as a GFP-750, which to my recollection was never offered with a phono section, but was otherwise very popular when is first came out.

What phono stage are you using, amd what is your budget?

Never mind.

Now it’s the GFP-565, which has a more than decent phono section.
