resembles a buffered corda, but buffered with opamps for whatever reason. many opamps don't like being used at unity gain and are prone to oscillations, so I think putting EL200x or something along these lines instead of IC1 and IC4 would be better. the whole input stage is questionable. there are some other things I don't like about this circuit but will only say that meta42 design is likely to beat the crap out of this amp. except for xfeed of course.

It reproduces what you put into it, I hate listening to bad recordings on this because, this reproduces everything so accurately that you put through it, it is a night mare.


sign of a mediocre equipment.

Hello,

It is almost exact copy of the original Mr Meier's crossfeeding amplifier. ...

I think the article by Mr Meier himself at HeadWize is not informative. You can learn to modify crossfeeding frequancy and magnitude of it.
