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.

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.

DeKay
dlcockrum, thanks for the recommendation. I’ll look into cartridges as well.

DeKay, sorry about the confusion. I made a mistake with the model number. One thing I should add for full disclosure is I bought the Technics mostly out of curiosity and based on what a lot of folks had said about the quality of their direct drive tables. And this one happened to be so close to me. As for the budget, I’m thinking something around $400-$500 used should be better than what I have in my 565.
My original concern is/was to spend the money on the phono stage and only get incremental improvement due to the quality limitations imposed by putting the 565 downstream from it.
Yes, the GFP-565 has a very good phono stage. You'd have to spend well over $500 on a used phono stage to best it.

I agree with dlcockrum - your best bang-for-the-buck upgrade would be your cartridge.
