Hegel Sound Engine

[soundboy]

Hi everyone, this is my first posting on this site and was basically wondering if anyone has had any experience with the 'hegel sound engine' from http://www.profusionplc.com

from the pdf, the device looks pretty simple to build and has some good specs. check it out, what do you all think?

Hi,

Can you share with us pdf because I can not find it.
It will be very interesting to see ‘Hegel sound engine’.

Thank you

After 5 years it's probably gone from that site.

And 'soundboy' hasn't posted since 2002 either!

Apparently, Hegel's "sound engine" is a high-end local feedforward amplifier design. Like Quad's and other approaches to this principle, it is claimed by the designer, Bent Holter, that this avoids the usual shortcomings and inefficiencies of standard class AB audio amplifiers. Probably nothing new here and after all, 15 years have passed since the OP.

searching the Internet for new patents on the topic I found the following US20130181778

Although I dont own nor haven't heard one yet, Hegel amps have a very good reputation, so it's a circuit worth looking into.

Any thoughts about this feedforward design? Anything unique or interesting?

Somewhere on youtube there is a talk on Hegel's philosophy by the owner of the company who is also the lead designer. The "sound engine" is basically a computer which corrects/adjusts for all the little errors that amplifiers are known to make.
