Hello everybody .
I have read these pages (but not completely) that have intrigued me.

do you think it is possible to build a volume attenuator using magnetoresistors?

Second link --- paragraph--0004 is contradicted by a well known and well loved --cheap UK power amplifier ,given good write ups at the time and very large numbers sold ( I have one ).
The amplifier much talked about on DIY Audio the NAD 3020 of 1978 vintage which has ---=Soft Clipping so that premise doesn't hold water.
As its at the beginning of this Paper it is used as a premise for all that follows.
There are scientific Papers published on the deficiencies in magnoresistors but my point is the initial justification is flawed .
