I received my first Beresford dac today. A second hand 7510.
After opening the box it was clear that this unit had been modified.
The analog output op-amp was LM4*** (very small print). There were four 47 uf Nichicon Muse caps. On both sides of the op-amp small polyprop caps.
After reading about 7510 mods this must be the Mod 21.
The power unit is a light "Vanson" brand. My question is about a new power unit:
a) Should I try an old fashioned heavy transformer with little electronics
b) A modern laptop power unit
Which would bring sound improvements.
