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

I'm biased. Bought a Studio I preamp and Studio II Amp in 1977. Dean upgraded both in 1980 for $75 each. Bought an Adcom in 1988--slightly better than the II. In 1990, the Studio II needed repair. Cost $120. In 1995 bought a Studio IV when I built my home theater system. Vastly superior to the Adcom. Shortly afterwards, crossed two speaker cables and damaged the new IV. Dean repaired it for $110. Last year I replaced the Adcom (which was deteriorating sonicly) with a used IV.

I still use the Studio I for my TT pre-preamp and the Studio II for my back speakers.

One of my Studio IV's has a detachable power cord. The other does not.

I'm pleased with my PSEs. My only question is that Dean must be nearing retirement. Not sure what will happen after he leaves the business.
I have owned two of these in the past and would give anything to have them back...used with a pair of KEF 102 monitors and you have sonic excellence if not Nirvanna...why they stopped being made is beyond me...use them with their comparable preamp if you can
I am currently using the Studio IV and still have the Studio V's which I bought several years ago. The monoblock Studio V's have a bit more 'heft' and bass as you would expect, but the IV has, perhaps, a bit more focus, though I haven't done a lot of back and forth comparisons.
I was auditioning a number of used amps for a second system and the Studio IV was far and away the best I had heard in the $500-700 price range. At the moment it remains in my main system as I focus on other upgrades.
I have a PSE Studio 2 amp. When I recently purchased this used I was not expecting nor prepared for the excellent sonics this amp produced. In fact it sounded better than many new solid state amps I have heard. It presentation is slightly warm with rich harmonics along with a large soundstage. Like many quality amps its sound steadily improved over a 24 hour period.
