Thanks for the replies.
I have gone through the tube changes, have Mullard NOS input/driver tubes and Svetlana EL34 output tubes. As you say Saki70, it does make a difference to the performance character of the amp, much more preferable to my ears.
I was really asking if anyone had done any major component changes such as cap and resistor changes to, probably, better specified/quality components.
The Prologue 2 is such a great amp once the tubes are changed to other ones, I was wondering if anyone had taken it any further, or whether it is possible to improve the performance.
