Specs on PSE Studio Mark IV

Hi folks,

I have a PSE Studio Mark IV driving my Thiels that I am happy with. I am playing around with putting a simple preamp in place of my receiver (Outlaw 1050).

One option that I'm considering is going passive so that my cd player has a more direct connection to the amp.

But, I don't have any literature on the amp. Does anyone have the specs on this amp that they could share with me to help in matching for impedence and capacitance? (which I think are the critical aspects of matching for a passive system if I understand all that I've been reading)

My cd player is the NAD 540 which has 2.2 volt output with 300 ohm impedance.

Anyone else gone passive into the PSE?

I'm also considering a small tube preamp and am toying with the idea of DIY for either the passive or the tube.

Thanks,

Chris

I have a PSE Studio IV driving Vandy 2CIs in a small office setting. It is an absolutely transparent amp with smooth extended trebles and deep, rich bass tones. Anyone that owns this amp will probably never want to give it up.

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)
