I checked the data sheet before inserting the chip and it appeared to be of a similar spec. I am not sure if the circuit has been optimised for the opa. Any ideas?

In the short time I've had it running I think it sounds a little bit crisper... slightly more detailed.

I will now swap back to the OPA to confirm this...back in a mo

stick an oscilloscope on it.
see if there is overshoot at the output, or worse still ringing.
Check for ringing on the supply lines/pins

From what I can hear...it doesn't sound any worse

Andrew do you have any recommendations based upon the BOM I previously posted?

I have a OPA2132PA Dual FET op-amp, do you think this is worth trying?

Thanks

Richard

Great Scribble.
It seems to take forever to reach some parts of our small world.
