Great stuff. So, with reports like this and the fact that M are using linear power supplies in the Anniversary stuff, it looks clear that it makes a difference. So, what is the theory behind the improvement and does it have much bearing on whether power conditioners/power cables are snake oil or not?
Cheers Tintin Power supplies, power conditioners, and power cables are definitely not snake oil. It comes down to accuracy. Power conditioners and power cables help to reject AC line noise from the outside world. Power supplies are the main contributors to noise and jitter from within the box. The theory is that: 1) less noise and ripple provide more accurate voltage levels, and 2) faster response times provide more accurate timing. Accurate voltage levels and accurate timing are essential for accurate sound reproduction. Having said this, good power doesn't need to cost a bundle.

Hi guys have a G68XXV that is very slow to start after cold etc. I'm thinking it's power supply time, anyone able to make a linear one in external box like Mr Lee but a bit closer to Sheffield UK?
If this is not possible is a beefier normal type worth considering internal or external.

After many years into the G68 PSU upgrade, are there any issues or are you still happy with it?
