Perpetual Technologies P1,P3, and Monolithic PS

Ditto.

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...

I have PT P1&P3 (no Mono PS) and had the WrightMods done to the DAC. They are very revealing and transparent and the DAC can be a bit ruthless by itself. The WrightMods took away all etch, leaness, etc., and the DAC sounds so good it took me 2 weeks to plug the P1 back in after getting it from Dan Wright. It's worth the $450.00 for the complete mod - the new system beats three $2,000.00 - $3,500.00 current Cd players I borrowed to audition.

(1) Does anyone know the upgrade service in the market for P-1A or P-3A. I purchased Revelation CRYO-Cables for Power Supply & I2 months ago. It really helps. But is there any professional company offering upgrading services in the market??

(2)As I read the information that other Audiogon members mentioned there is a software called "SOCS Solution" for P-1A for sound enhancement. Does anyone know the details?

I owned this Trio for 6 months. My P3A had been modded by Dan Wright and I had the speaker correction softwarre for my Thiel 2.3's. I ended up selling the lot because after several months of listening I just did not like it. On my system, in my room, with my ears, I just thought the wide variety of music I played sounded mechanical and fatiguing.

I had this experience recently hearing this trio on a friends system that was significantly better than mine. This is just my opinion based on my experience.

You bet. Empirical Audio does a TurboMOD to the P-3A that makes it rival the Meitner for redbook playback. see details on Audiogon or at:
