I'd be interested in a kit as well; do you have a price estimate?

The last kit was it $30, or $40 a board? I can vaguely (I'm 55 next month!) remember it was one of those two, plus shipping methinks.
My interest in this is that I heard a AudioNote Dac 3.1 with the silver transformers in a system I'm familiar with, and it sounded really good, the best I've heard in that system, or anywhere. So I reaaally liked it, but I can't afford it. My question (sorry for the wait)
is how close can I get with this? Do I need to add some transformers for I/V conversion/filtering to get more of that AN sound? I should add that I have read the old threads, but there is not a lot about sound quality on the threads.
Thanks in advance!

Hi Quanghao, how would you describe the sound of this version compared to DAC ASH?

I see I confused the board and kit. Sorry! I did not mean to say the kit. I meant the boards were about that price. Will you be selling resistors or anything else along with the boards, if you sell boards?
Changing the subject, you give the option to use three different tubes on your pre/IV
board - very cool - and I was wondering if there is anybody that has tried all three and compared them. Anybody have some experience or speculation about how they will sound?
