Managed to cram the AudioNote caps in there, any larger and it would not have fit.
Switched back to stock opamp, and put Slow Roll Off filter on.
So far the slight edge has receded and things are sounding excellent. Will have to run these caps in a bit more obviously but very good stuff.
I had been neglecting this player for a long time because of the top end, but no longer.
This is the 15v power upgrade version no extra goodies.
Thanks for the recommendation!
I'd also like the thank neog007 for the excellent first post, info preserved for all time
the caps should be positioned exactly as the stock caps, over the cut off holes.. underneath of the caps should be same level with the buttom of the pcb..
sorry, my english is not enough, hope images helps..
