Densen amp

[darian]

Hello,

Does anyone have any schematic from any DENSEN amplifier? I'm very curious about these ones since they claim no feedback and very simple topology and the measurements are nothing short of awesome!

Thanx

They claim a lot.
But the amplifier is only free of global feedback, and the measurements are somewhat less than stellar.
Have a look here for measurements on their flagship poweramp B350.

@ 10 Watts the K3 distortion is only 40 dB down, and @ 100 watts a bit more than 30 dB down.

Hi,
be tremendously suspicious about amps that measure good. They don`t ever sound good.

I also need schematics of the follow power mono amp:

Substantial for high sonic quality are not the low order THD components (still high values without global NFB). Only high values of the high order components (>H7) results in bad sound, additional power compression of the power supply and bad GND management.

So I am sure that this amplifier sounds very good, without having heard them.

That I think is not true.
In my experience does amps that measures bad also sound bad, but amplifiers that measues very good, does not necessarily sound good.
So I think it is the other way arround.

I do not really agree to that.
If you look at music, it contains even order harmonics, and none what so ever uneven.
Uneven harmonic distortions, has simply nothing to do with music, therefor the uneven are the most mallicious ones. In addition it is mostly the lower order uneven harmonics, which are these closest to the basic tone, that are the worst ones. But I do think higher order unevens are uneasy to the ears as well.

In this particular case something must have gone wrong. I´ve never seen any amp, which was not a tube amp, distort that much @ just 10 watts.

What can I say.

Kurt von Kubik,
I did not say all amplifiers that measure bad are good sounding, however the price of good measured performance is lost subjective values and there's no way to circumvent that relationship.

I say! That every amp measuring bad also sounds bad.
And I also say, that good measuring behaviour not at all excludes good sound.

Kurt von Kubik,
I comprehend, however I say the opposite of that.
