Perpetual Technologies P1,P3, and Monolithic PS

What is the deal with all of these units on Audiogon? I have this setup, and it is by far the best D/A combo I have ever heard for anywhere near the price!! I used to work in the business, and we had a lot of high end gear. The differences between this combo and the high end CD players or DAC's is very miniscule. There are even posts up for all three with a price of $800! This is the bargain of the century! I am wondering if people are using inferior transports, cables, preamps, amplifiers, or what?? If anyone has these units for sale, or have sold these units, please let my know the reasoning.

In response to a suggestion from another Audiogoner who has similar equipment, I bought a P-1A D/D, with Monolithic Pwr. Sup., on their money-back trial plan.

I used the unit with my CEC TL-1X/Chord DAC64 combo. Apparently my old ears aren't sufficiently golden, because I couldn't hear an improvement, or at least one that would justify the additional expenditure. So the units were returned.

I also have a Burmester 001 player, and as far as I'm concerned, a comparison of it vs. the CEC/Chord is a toss-up. I'm extremely satisfied with both. (I bought the Burmester after having sent the PT stuff back, so I have no way of knowing if its performance would be improved with the P-1A.)

I had those units too, and sold after 3 months of using, because nevertheless I have got improvements they were not substantial.
But it was really annoying it was generating (especially P1) some kind of noise and I could not watch TV when it was power up. It was interrupting music by itself, I could not find the reason. I have heard bigger improvements with some old Theta 16/44.1 DAC hooked up to my old Arcam Alpha 6 them with this 24/96. Those unit got me better liquidity, bass was a little better defined but somehow liner, width and depths was the some, dynamic in micro scale was definitely better, but in macro was in opposite way.
I would keep it but because of interference and these annoying interruptions I have decided to sell, even it has given me 10% of overall improvements in some fields. But definitelly it was not class A.

I also was not happy with a P1a that I bought used. I hooked it up with MSB Link Dac (to replace a DTI Pro). Yes I could hear tremendous detail but actually harsh sound, like jitter, and it changed the character of the Link Dac *completely*. From being dynamic and open sounding, the Link became very refined and buttoned-up sounding, not the sound that I like from music. But the worst was the subtle harsh undertone that gave me a headache after a while. A faulty unit? Could be...
