PSE Studio 4 amplifier - any good?


I am thinking of buying a used PSE Studio 4 amp. Anyone out there care to put their comments on this amp?...thanks

Yes, Albert, this is the same, Professional Systems Engineering.

Great amplifiers, the Studio V's are incredible.
I own one of these, bought it used a couple years ago. It was a good value, and I believe it had been rated Stereophile Class C. At first I found it a bit lacking in the bass, but perhaps I was expecting a lot from a 100 wpc amplifier. Then I replaced the power cord with an audiophile cord (a Stealth M-7, actually) and it became a different amplifier, with strong, tight bass. (However, the original cord was hardwired in, so replacement was somewhat of a pain.)

I'd say the Studio IV is a good value, given the prices I've seen for it used. If you want to upgrade it, have an IEC socket installed and try using a good power cord.
I don't know about the Studio 4's, but the studio V monoblocks are excellent. I have a pair of the Special Editions that are great, along with their PHE hybrid preamp. Great sounds, especially plugged in to a Power plant.
I own both studio 4 stereo and and studio five monoblocks and have been very happy with them for over 10 years. My current office system is rega planet, studio SL preamp, studio five mono blocks recently upgraded, all Nordost blue heaven wire balanced to the amps with a new pair of Totem Arros. I ran this system unbalanced with the Studio Four while the 5's were being upgraded and the sound for a small system was still stunning. It is the most musical and reavealing system I've ever put together for a small space for the money. I think Dean at PSE does a great job and his equipment at this price point new or used is still hard to beat. It just got better when the upgraded 5's got back. I'd reccomend. ACR
