Scott Nixon outboard DAC's, any good?

I've the 47 Labs Shigaraki transport hooked to a Scott Nixon TUBEDAC+. This combo is sooooo smoooooth, with detail and rhythm. The Scott Nixon seems to allow dynamic nuances to really drip with emotion.

As far as Scott Nixon's DAC being a "stripped-down version of the 47 Labs," it is just the opposite: the 47 Labs units are more stripped down than the Scott Nixon DAC. Both these units get the timing right and are very direct, but are non-linear, and show alot of triangle-wave distortion in upper frequencies. Neither unit has an adequate power supply, and one of them has a much better pcb layout than the other. Both have jitter levels that can be improved through a-synchronous re-clocking, and both do not have a fully-tuned PLL.
Given all that, I still have to admit that both these units sound better than 85% of the DACs on the market. Scott's KIT is fun to build, priced fair, and a nice learning experience. He is very helpful if you have problems along the way.

What is The Scott Nixon wed site or where do i go to purchase one?

"Slawney", or anyone, can you comment on how either of these zero upsampling dacs compare to the Audio Note 1 dac that seems to be fairly popular? (I think it is the model 1, or 1X)
