used DAC for under $350 Channel Isalnd....


Has anyone done a side by side comparison between, or have experience with the Soundstream DAC-1 and a Channel Island VDA with the accompanying power pack. I am currently using the Soundstream and I was thinking about an upgrade.
The Channel Isalnd has a had a few really great reviews and I am fairly confident that the output would be better, but by how much I don’t know.
Or perhaps if someone could suggest another used DAC for under $350.00
My current amp is a Rotel, soon to be either a Musical Fidelity or Krell 300iL.
Any help would be greatly appreciated.
Thanks

Correction: the assembled TubeDac from Scott Nixon is shipped to a buyer for $400, slightly above your requested limit of $350. And the assembled DacKit is shipped to the buyer for $250, leaving you with some extra cash to buy more CD's.

Here on Audiogon, Viggen already owns the DacKit, and I think he has compared it to another new design with a higher bargain price. Perhaps he will comment on his unit which falls easily under your $350 budget limit.
I think Viggen is changing his set up. I wonder if he decided to keep the ScottDixon...His Gaincard and many of his power conditioning devices, as well as cables are up for sale.
