PS Audio GCPH Phono Preamp

If you do try one: be certain to replace the fuse and power
cord, with some upgraded products(ie: Hi-Fi Tuning Supreme and
a Synergistic power cord). This piece already employs fairly
high speed rectifiers and responds surprisingly well, to these
two tweaks. If you can solder, install HEXFRED or Schottky
rectifiers, Belleson regulators and WBT RCAs, for even better
presentation. The improvements are not at all subtle. Muting
& mono switches, remote volume control and phase inversion are
why I tried the unit. It takes a bit of work, to draw out the
performance. Unless you use an SUT and a very low output
cartridge; chances are, you won't experience any noise at all.
That's unless the transformer is not moored down properly.
Some users have had a problem there.

I like the ability to adjust the output so I have no idea what Lwin means when he says output is on the low side. Using it with a Ortofon 40 mm so maybe a MC is not as compatable and that is what Lwin is using. Very satisfied with the PS audio GCPH.

There aren't many phono preamps out there, that offer more than 66db of gain.
