Nearly gave up on the V-II, but then the Commander 6 A PSU arrived.
The sound, with original PSU is not really hi end, just a reasonably unobtrusive sounding DAC.
Bit mid-fi, not getting a "I am there" feeling of higher end DAC´s.
Light sounding, and not too engaging.
All that changed quite dramatically, with the add-on PSU.
To get a suitable power plug to fit the V-II, I mutilated an old Nokia cellphone charger - 3,5 mm, fitted precisely.
After warm up, I was greeted with a dramatic, bold sound, with a acute sense of all small details, but in its own context.
That is, not spread around loose small details, but a complete musical experience with a "I am there" feeling.
A fat, cozy sound, but with live, space, drama, and a hard hitting lower bass, at least with my equipment.
So, yes - I fully agree - the PSU delivered with the V-II just doesent work too good.
But, its easily upgradeable - in my case about 15:-, and some soldering.
