earlier Musical Fideltiy V-LInk to new V-Linkll

Elboroth2 - The references that I have seen must refer to the internal power regulation. I agree there is no external power. As I said, I have no real details, just some one line references that I have seen.

I just read that the V-link II galvanically isolates the computer's power from the DAC, the V-link does not.

Realremo - do you have a reference? What I have read is that the galvanic isolation may just mean that the signal is isolated when Toslink is being used. I don't think it does anything for other interconnects. It would be nice to know if it has galvanic isolation in addition to the Toslink.

OK apparently I was smoking the good stuff that night, the above article says nothing about the V-link II. Sorry, jumped the gun there.
John Atkinson assumes that the V-Link I is not galvanically isolated, because Antony Michaelson of MF suggested he use the optical output if possible.
I'm not slamming the V-link, I own one. And you're right, I cannot find anything on the V-Link II that claims galvanic isolation.
I also tested both coax and optical out of my V-link I, and I cannot hear a difference.
The Vlink II manual specifically recommends the use of an optical cable for galvanic isolation.

Realremo - thanks for the clarification. I thought it was too good to be true at that price.
