I'm really pleased to see someone else doing a linear supply - well done KC. A few questions and comments:

You went for two connections after all - does that mean you kept the two return lines separate? And did you have a single connection for the +5V?

How do you earth the G68 - is that through the power supply?

When you say it sounded better - is that through the DSP6000's? When I did my switched vs linear comparisons, I was only using analogue outputs and passive speakers. I guess you're saying the LPS is better even when you use the digital outputs? Presumably there is less jitter? But it probably helps getting the PSU outside the box alogether.

If that's the case, I think there's a good justification for having linear supplies with players, and even with the HD621. They don't have much room inside, so an external supply would be a great advantage.

I fought shy of making an external supply, as I didn't know whether it would work at all. But this looks like an attractive solution now. If I was getting all ambitious, I might think about an external linear PSU with multiple outputs for the player, processor, etc?


Great stuff, Nick
