Hi, PMA

According to a large number of our listening tests there is an audible difference between the same stage with and without error correction

Could you describe what sonic difference between one amp without error correction and the same amp with error correction (especially Hawksford type)?
Is it more audible in bass or midrange or treble?

This must be in the Air I also have been recently playing with These ideas see attached

Well - I do not prefer speaking about midrange, treble etc. The biggest difference is in smoothness, liquidity of sound of the circuit with error correction. Also better in musical instruments resolution/definition.

Looks like interesting circuit idea. Have you already tried it?

Hi, PMA,
Thanks for the explenation.
Non feedback power amp is usually notorious for the bass. It dont have control. Does matching non feedback amp with EC will be perfect?

I made 3 component value changes, because the circuit had been collapsing when overloaded.

PMA! about distortion? I have just simulated hawsford's error correction. It has a improvement at 20khz input signal, 38mV 2nd -> 1.6mV
