There is a guy in France with an audio website that has the most information on "memory distortion" that I have seen (link below). He has recently started participating on the DIY Hi-Fi and DIY Audio forums.But like I said, I think that it is a dead end. If you read Peufeu's stuff, he comes up with a "magic" resistor that helps stabilize the operating point of the active device. His theory is sound, as I established with simulations. But the problem is that the circuit both measures and sounds better without the "magic" resistor.
The conclusion I reached is that there is something else going on that is more important than the instantaneous temperature fluctuations of the "memory distortion". But I could be wrong. I've never heard the Lavardin amps myself. Maybe they sound even better than the MX-Rs!

- No, it doesn't reduce capacitance, just the parasitic resistance. - Al Sekela 09:51:18 04/11/07 (0)
