Review of PSS600 amplifier in Australia
Ian,
As said earlier, we are about to ship a pallet to NET next week.
I already informed Billy about the amplifier I will add for you.
I will prepare a PSS600 from the PA series (same as for Scott) with the following modifications:
26-db gain,
120 000MF of JAMICON capacitors instead of 80 000MF.
It is in fact the amplifier I used as I am wiring tomorrow an MKIII amplifier for my personal use.
What will differ from an MKIII from an MKII amplifier?
Modified ground around the capacitors (if you open the PSS600 you will receive we added some wires between the bridges and the capacitors, we modified the MKIII board to have two complete fills - top and bottom - around the mains capacitors),
I came back from the twin bridge system to two bridges wired in parallel.
I hope you will fall in love and let it know to the magazines you are working with!

Scott will soon receive a custom PSS600

This I have very good feelings about, because I already know the tonality of his amp through the mids! And the amp will be optimized for exactly what i am doing with it! His amp has that smoooooooooth tone through the mid band!
This custom amplifier is an evolution of one of the studio amplifiers I am working on since 3 years time from now; all our “regular” power amplifiers taking benefit of all my investigation.
This amplifier has the following characteristics:
Same box and PCB (MKII +; Scott received an MKII one) that a PSS600 or 1200,
2x150W at 4 ohms
2x120W at 6 ohms (as it will be loaded by 3 2441)
2x100W at 8 ohms
40 000MF per channel
2x 400VA round transformer (same VA used for a PSS600).
Upon Scott’s request we will add binding posts, set the input sensitivity at 1V and remove the balanced IC (it can be placed back when ever you want, you will have to remove a wire link bypassing the balanced input stage).
I am happy that the PSS1200 Scott is testing is very smooth, as Scott says it is smoooooooooooooooooooooooooooth.
I intended such a warm sound as almost all amplifiers you can hear today (transistorised amplifiers) not only gives you pain in the neck listening at them for more than 10 minutes!
Unless the recording is bad, you can listen at high SPL PSS amplifiers, never will your ear get tired and damaged in any case.
And they have a lot of personality too, they sound well with the right tonality!
MKII- vs MKII:
Deeper and more defined bass (perhaps what Scott was complaining a little);
Warmer low mids;
Mids more precise and even more present;
Mids less shinny, if ever they were with the MKII board: I would say more graceful;
A greater stereophonic image where sound is not only coming from the speaker area only: imagine that the stage is located between Los Angeles and new York and goes as far Alaska and of course up to the sky!
