I have Studio IV and Studio II amps, along with the Studio One preamp. All excellent pieces. I've heard the Studio SL is very good as well, and if it has the optional phono stage it is worthy also.
Be forewarned that there is virtually no documentation available and the IV's are not easy to work on. If they are in good working order you will be rewarded with rich yet neutral sound.
From what I understand the IV amps were the choice of Vandersteen to voice and demo their speakers. I am currently powering a pair of Thiel CS2's with mine and while the Thiels are still a touch bright and analytical, the PSE really takes control of them and makes them submit. I have yet to find a speaker that is not a good match for the amp. Some others I have used include Chapman T7's, Infinity RS5's (80's gen.), Infinity RSM, IMF "The Studio", MA Silver RS6, Sylvan Elite and Premier's, Angstrom Obbligato...just to name a few.

The specs are:
Output Operation is A/AB
Continuous Average is 100 watts into 8 ohms and 195 watts into 4 ohms
Current is 18 amps continuous into 8 ohms for over 1 minute
Rated THD is 0.01%
Rated Slew Rate is 100 V/uS
Rated Power Bandwidth is 0 hz to 100 khz
All direct coupled (no capacitors in the signal path)
Front end uses Class A FET which means high input impedance (which avoids interaction with cables and preamps)
Amp is stable into all speaker loads
There is a Stereophile Review of this amp (VOl.13, No.1, (Jan. 1990)
Here is my current living room setup.

I have a PSE HL1 hybrid preamp. It served me well driving home-built AtmaSphere M60 amps and Greybeard Audio 2/2 speakers. I upgraded to a used Rowland Consummate line and phono stage, which was quite a bit more transparent, but that was mostly to address the limitations of the Black Cube phono stage, not the PSE line stage.
