See the superb review in the Absolute Sound where they have recommended the stock GCPH as the finest $1000.00 phono stage that they are aware of. Our modification takes it to a new level.
The PS Audio GCPH is a remote controlled balanced phono stage with excellent performance. It plays all cartridges. It has stereo/mono switching, front panel gain, impedance matching and phase reversal. It can even be used as a full preamp with remote controlled volume in a phono only system.
We ship modified units worldwide.
The 10Audio.com review summed up with:
"The stock GCPH is a good sounding unit at its price of just under $1k, but the Underwood HiFi mod is significant. It is seriously recommended for the wonderful sound it provides. Notice that I did not say
wonderful sound it provides for the money. The Underwood HiFi modification moves the GCPH definitively into high end territory and makes the unit competitive with other phono preamplifiers in the $3000-5000 range. That is saying a lot for a component that sells for a very reasonable $1350. I would easily choose the Underwood-GCPH over the ARC PH5 ($2000) or Art Audio Vinyl 1 (~$3000). On a performance-price basis, the Underwood HiFi-GCPH is the biggest bargain I know of in audio. Try it. You may find that the price of admission to true high-end LP playback has became affordable."

One customer emailed with:
It arrived and plays. IT IS HEAVEN ALL READY. Even with a Stanton EEE you experience a brilliant level never experienced before(second turntable). With the Frog it is so open, so fast so clean. Oh boy.There is no cd player able to achieve this level of resolution and space. Even a wadia 861 SE Statement update from Steve cant reach this outstanding level. This after a few hours playing its now already sensational. Within a few months I will write a report and send it to you. You can place it on the AudiogoN.
Fantastic job!!!!!!!!!!!! Casper"

SONIC CHANGES of LEVEL 1 MODIFICATION
-We make a major improvement to the midrange. It is more liquid and tube-like. It sounds warmer and more like a tube stage. This was the major design goal of the mod and we think that we have accomplished the task.
-The unit is Quieter.... The Silences are BLACKER...It thus resolves more low level Detail, has better ambiance retrieval and is much more three dimensional.
-Bass response is improved. Both bass depth and mid-bass slam are much improved on the Level-1
-Imaging is more focused while the entire soundstage is both deeper and wider.
-Transparency is improved. You get a much cleaner look into the musical soundstage.
-Dynamics are improved. The stock unit is good here. Once modified it is like we add a few more dB of headroom. We add killer dynamics and has better pace. It seems to play much louder on peaks. There is a more excitement in the music. It now plays with the competition that sells for thousands of dollars more.
-Treble detail, both micro and macro, are improved and now keep up with anything that we have heard under $3k
