PSE Studio One


The Studio One was purposely made as small as possible to allow it to be placed almost anywhere.

As an option a moving coil preamplifier may be installed.

The unit can be rack mounted on standard 3-1/2" centres with an optional rack mount kit.


Frequency response: 20Hz to 20kHz

Gain: 20dB (line)

re: Studio One

Have studio one and two and they are without question simply beautiful in all respects .
build quality is stellar, as is the sound quality . everything is built to last..and last.
With my Dahlquist DQ10S (mirrored pair) I get chills when I sit and really get lost in the music . separation is out of this world..must audition if you ever get the chance .
Big two thumbs up !!

re: Studio One

I worked at PSE while I was in school at Brown Institute in Minneapolis. Dean would bring in competitors equipment to compare. It was the most fun job EVER! The PSE amps were scrutinized against everything, price, gold plated PCBs, no matter. He'd come in and tell me to make mods to his stuff so he could compare. He offered to sell me a set when I graduated, but I didn't have any MONEY! I'm still on the hunt.

re: Studio One

I still have my original set from decades ago and I'm keeping them. But browsing on the internet I found these for sale:
Scroll near the bottom. Only better *quality* I've had is the original pro Boulder amps.

re: Studio One

Does anyone out there have schematics for the Studio One?

re: Studio One & Studio Two

Can anybody supply a circuit diagram for the Studio One & Two amplifiers?
