The DAC I have sold was the roksan k3.I would have bought the elements weeks ago if the seller hadn't sent it on a world tour .As for the njc I do like the idea of UK hand built I'm also a fan of arcaydis speaker I own to sets .I have sent a email of enquiry to njc so I haven't committed just yet.
Great DAC. I had one a couple of years ago - Roksan were selling them off cheap (got mine for £399). I think they slightly missed the boat - their K3 CD player had all the DAC capabities and in the end I think Roksan (or the dealers) heavily discounted them. I'd planned to use mine for playing files off my laptop, but in the end, never did. Opted to get rid of it and sent it off to Ebay. Pretty much made my money back again. Lovely DAC though, and terrific build.
