Hi Wayne!Audio Note has offered kit DACs and amplifiers in the past, but stopped doing so as of last winter. The finished goods require all the available time, attention and parts!
Yes, given the variety of levels available for many products, it is possible to have an item built nearly custom.
Of course, I do have my pair of audiophile Pi Fours (Sevens?) here being fed by some lovely and rarefied Audio Note gear. If you ever find yourself in the East . . . . .
Maybe there'll be another alternative show in the middle of the country where we can mix, match and explore!
