Cool, thanks for that. I was just a bit concerned when the voltages weren't over 10v as mentioned. Didn't think there could be too much wrong as it's doing everything right.

Still evaluating but from what I'm hearing I'd say it's added more accuracy to the music, placement is more precise and there seem to be more micro details coming through which adds a lot of nouonce to vocals ect. Hasn't really done much to the sound stage, this was already very good.

Happy so far.

Thanks to everyone for making this available.

Only minor issue is a small amount of hum, I've got 95db bass speakers and it's just audible right up close. The transformer is well away from the board so I don't think placement is an issue.
Is a toridal better than a normal"box" transformer?
