Death of Gain Clone

[widowmaker]

Here is my project of simply to realize Feedforward Error Correction Amp
(A+B).
The most iportant in this project was:
The Amp must be very cheap and with better sound than the "famous"
"Gain Clown"
Here is a schematic:

The output inductor:

Good luck but I have serious doubts that you will be able to "kill" a Gainclone. Are you aware of the competition?

 

[tschrama]

Cool idea to beat a gainclone but what part of this amp is the Feedforward Error Correction part?

Yes
We already made the comparison...

 

[rick57]

We already made the comparison...

... and the differences were?

 

[richie00boy]

I like the current sink, simple!

 

[widowmaker]

We already made the comparison...

... and the differences were?

More tight and real bass, more clear and natural mid and high frequencies, more "air" and 3D...

 

[peranders]

More air and 3D, congratulations but how looked the Gainclone?

 

[richie00boy]

I think the picture on his website shows this amp.

The GainClon compared with the DoGC(Death of GainClon) is like
a simple classB amp compared with a classA ;-)
If you want to understand what i talking about, make this amp and
listen it

More tight and real bass, more clear and natural mid and high frequencies, more "air" and 3D...

sounds like words from ''audiophile'' cable posts.

well i suppose the competition is being grossly underestimated here.

 

[widowmaker]

I think that the name of my project inflame passions among some of GainClone makers/owners

The competitors in my cause:

Gain Clone:

DoGC:

Let my friends/colleagues talk about the difference...

He-he, my sweet little Gainclone!

 

[Nemophyle]

the gainclone looks better on your pictures

i don't like the gainclone sound very much anyway,call me crazy but i prefer the sound of class A amplifiers like the DOZ (Death of zen, looks like there is lots of blood in the Audio amplifiers world ) or good digital amps like the 41hz or autocostruire, or even better UCD modules, when lots of power is needed...

but lets talk about what is so good in your amp, i'm always looking after building new amps, but i'm poor.

the bgaudio.org site looks wonderfull anyway ! it's a shame i dont understand a thing !

well if you compare that to the words of gainclones lovers (" less congestionned mids" ) it's not so different, i suppose it depends on wich side you are

The output stage is more 'transconductance' than error correction.

Hi, Darkfenriz,

The output stage is more 'transconductance' than error correction.

I don't understand this. Better or worse than error correction? I feel that error correction is already a big help for low biased classAB If this is better then.....WOW

Hi, Widowmaker,

Is it possible to make your DOGC with higher voltage, say +/-50V? Cascoding the differential Jfet or use high voltage bipolars for differential?

 

[lumanauw]

Hi, Widowmaker,

I see the important part in your DOGC is the 47ohm resistor.

Sometime ago, I proposed similiar idea but it is said to be ordinary CFP

In my idea, R5 works like your 47ohm, the difference is my idea works as "current source" final trans are common emitors, while in yours, the final transistors are emitor followers.

What is the degree of difficulty to build, vs gainclone, or a Nelson Pass class A amp?

And what was the total parts cost?

Thanks
