Mod your Beresford 7520

OK, thanks for that. Is there a worthwhile improvement over the standard wall-wart? I know there is with my 12V linear, so I wouldn't like to lose that improvement.

I haven't tried the 7520 wall wart. I just plugged the Maplin in straight away as it did make a small improvement to the 7510 so I assumed it would with the 7520.

I found the same thing with my 7510.
It was like pressing the "Loudness" button in my system - too much of everything.

No haven't even thought of trying 13.5v in mine.

Will do tonight and post back.

You should too when you get a chance? Might be useful info?

Have you guys had a meter on the PSU output? Is it pretty close to the stated voltage? I am running my linear PSU at 12.5V (measured) as this was similar to the wall-wart's output.

Won't running the DAC at 13.5V lead to risk of burning out or damaging something if used long-term?
(I only ask 'cos I'm quite liking the description of the "problems" being listed with the sound at 13.5, sounds temptingly intriguing - sometimes I like the music shouting in my face!)

The spec is 12V to 15V, there are internal regulators. Also the PSU will likely sag a little under load. So if you measure 14V off-load, it's likely to be 13.5V on-load.

Anyone tried one of these?
