FS: IRAUDAMP1 Rev. 4.1 Eval Board
I only used this board for a short time to test it, but let me say it sounds fantastic. I was shocked by the lack of a noise floor. I couldn't even tell it was on with my ear pressed against the tweeter. This was a huge surprise after living with the "Tripath Hiss™" for so long.
Price is $200 w/ free shipping within North America. Other countries please ask for a shipping quote. PayPal preferred.
