Thought I must be losing it just now, this posting seemed to 'grow'. Guess you're keeping the relevant stuff together, Leo. Thanks.
I'm still listening to it and getting ever more impressed. I'm watching '24' on Sky HD and it sounds marvellous - as if previously there was a faint harshness to the sound which has now gone.

The big resistor situated behind the 7805 regulator can be replaced with a wire link if you have the Murata regulator fitted.Originally Posted by HighFidelityGuy

One more mod I must make: to change the blue LED dropper resistor from 1k to 2k2 as it shines like a bloody searchlight at 20mA current

Stan: did I see you post somewhere that you had tried a linear PSU with the Caiman with favourable results, or did I dream it?

That's the one, Leo. It seems that Stan found a big linear PSU to be beneficial with a modified Caiman. Matches my findings - I guess both the Murata and Dexa regulators respond rather well to clean noise-free volts in.
