At least Sony is willing to admit there is a 'potential' problem. I use an outboard low pass filter and I sleep well.

I can't solve the problem of the Ayre making the Beveridge amplifier oscillate, can you say where you got the low-pass filter or if you built it yourself, can you supply instructions? Thanks.
My low pass filter is homemade, and the basic schematic is on page 11 of the linked application note. A 'full' schematic can be seen in the gain vs frequency plot on page 15, 'with RC'.
I'm no guru, but after repeatedly beating my head against the wall I came up with a filter that works for me. If you want to try one like it, send me an email for more info.
best regards,
reub
I think I can build that with the info provided. What cut-off frequency did you choose?
50KHz - Enjoy the journey!
