Hi Kurt,
I fully agree with you, PSU is "soul" of good amplifier (if amplifier is good).
sorry, I do not want to make publicity in this forum, I do not need, but I think that when it comes to real new technology may be interesting for everyone.
Now upload a photo of innovative integrated amplifier and PSU, look carefully, at present no company has ... the courage to put on a psu on amplifier board with audiophile performances.

Sound is very rock, not decrease under burst voltage (-2.7 V at 500W burst), this is impossible when I watch amplifier while playing.
power supply and amplifier have required very big money and long time for developments...I think!
research so it can produce results!

a couple of these and. .. all the problems are over

Hi AP2

Yes PSU is both the heart and soul of a good amp.
I´ll have to ask a few questions about the nice pictures.
The left one looks to me like a class D amp with onboard SMPS - am I right?
Is it a full bridge design or is it a 2 channel amp?
How much power will the SMPS deliver, and is it smooth and silent?
Does it need external smoothing?
Does it feature low impedance?

Lot of questions

Actually it looks pretty cool - did you do that?

Hi,
yes, DPA600 is integrated amplifier one ch 600w (4R).no bridge
psu on board not is traditional, true new topology IMD free.
at 600w 4R (80hz) without ripple! this is impossible, psu not have big capacitors.
but complex new technology, I think a short time,laboratory publicate this "RIPS" (rotary power system) on the web.
psu not use traditionals chip and trasf.
this psu tested with a Big mospower 500W class A-B without ripple at SIN 120hz(4R).

this produts & others, created from 2007 to 2009,(includes several test).
I think now is ready for marketing.
I are only a member of R&D

this R&D work on very different segments from audio...but hi-technology is...Hi-technology..

just to be precise, amp in photo is a commercial audio version. There is also a version for lovers / audiophiles. tasks change, ex. toroidal filter is different, solder color is red. PSU not change.
soon as possible, I would have the pleasure to send you one to listen (if you want).
Power out is to punch in the stomach.

Hi AP2
As you may know, I am the other half of the "Kurt von Kubik/Hurtig" project.

The PSU seems very interesting, and I would like to test it with the TC amp some day.

We are in the R&D of our own SMPS right these days/weeks/months. Our design is based on a Quasi Resonant controller. The controller is 100% discrete (No IC).
It runs at approx 200kHz at full power, and much higher at low power.

Is it possible to get a sample of your PSU??

AP2 · 8th February 2010, 02:24 PM

Hi,
I'm very sorry I did not know the other half to Kurt.
your psu, will certainly be good, I think that 200kHz is sufficient.
but in our laboratory (in 2006) with all SMPS topologies known, we could not get good results and performances on amp true professional or esoteric AB and class D .. good only for commercial audio use.
I say that I have not allowed direct with the company under license, may sell the products in the pic.
for samples, see what I can do, answer with private message for you.

AP2 · 9th February 2010, 07:21 AM

Hi Kurt,
you have a email (no msn)?
I answer for samples and documentation for power supply (2 model for TC)
Best regards

Hi Kurt

Could the following be used as a high quality buffer: LME49990 - Ultra-low Distortion, Ultra-low Noise Operational Amplifier

AP2 · 10th February 2010, 08:23 AM

Hi,

...very very good.
