Mint condition: boxed and indistinguishable from new. Used lightly for just over 2 months (ordered beginning of August, arrived 23rd November). New this costs €3979 (£3365) plus delivery and whatever duty costs end up being.
This is the highest level of specification for the R2R ladder DAC available, and is about as good as it gets with an exceptional balanced class A pre-amp section (+6db gain). See reviews.
