Sorry, we saw real, very different measurements of this amplifier.

Nice fake
Federmann, you should take notice of rules this forum has.

Number 3 is obviously one of your favorites...

Tests are false. False are the measurement conditions. Should be measured differently!
Could you please explain to me what is wrong with those tests? All I see is just a standard testing procedure, any amplifier I have would pass it with flying colours...
I see you have exquisite taste. http://www.diyaudio.com/forums/search.php?searchid=2907908
Congratulations, your measurements, without witnesses, is nice.
But we respect the independent measurement from other person. No Photoshop, no Fata Morgana, no hope & fog & smoke.

Sendy, the link you provided shows something seriously wrong!! Were you present at these measurements? Are you able to verify that *they* (the measurements) were done properly? Or that the amp supposedly under test was in fact the one being put forward in this thread, and that the implementation of said amp was solid?
Tony.

All measurements from man known as "flyingbird" of this amp is here.

Here is short test (only scope) - the same amplifier - measuring from other persone (PMA).
10kHz http://www.idea-envi.cz/hqqf/P6040043.JPG
may be 100kHz http://www.idea-envi.cz/hqqf/P6040046.JPG
and 100kHz once more http://web.telecom.cz/macura/obr9.jpg
Other information later....

Tony, let me tell you how this story began. Once upon a time, there was a high school teacher in a small Czech town. He wanted to do something wonderful, to change the world, to educate others. So he gathered that development of amplifiers went completely wrong way for the past fifty years and decided to make this right. There was only a little catch - he didn't know how... So for the past for years he has been showing simulations, renders but nothing solid. Only his own claims. For the first time, independent measurements have been shown (valachnet link). You can see his reaction... The amp measured in that link was exactly what Federmann had sold to a guy nicknamed Renown, who organized listening tests. The very same amp was later measured by an experienced technician.
Nice nick BTW, I should read it again sometime

Measured amplifier is my property. My people completed it from modules delivered by Mr. Federmann. He also supervised assembling process.
We made small party where we did also listening test. On this party was the amp measured by PMA (see the link above). Because time was limited for proper measurement, Flyingbird offered me to do complete test in his home. Result you can find on valachnet link.

Schematic almost looks like the work of Stee-fano, the Milanese Fai-Da-Te artist. Forgive me for having no desire to click the links.
Cut and paste designing seems to become a trend.
LOL
You got it!

Yes. We had enough of such practice 3 years ago. No need to continue.
