Any experience with the Scott Nixon Dacs?

I would like to try a Tube based Dac but I can't afford the
(to me) high end stuff. The Scott Nixon TubeDac kit looks like the product I would like to try. I am interested in any experience with the product line. I have a Harman/Kardon FL8300, DynaPas pre-amp (12au7 based),pooged Hafler DH200, and home brew speakers (ESS amt1 with Peerless 6" mid-bass), Kef driver based sub-woofer. Jazz and Classical are my music preferences. Thanks.
