Geshelli ( I have read) generally takes about a month, but all of their dacs are custom-built - you choose the case material (metal or wood) and color, the end-plate plexiglass color, the specific dac chip (ESS or AKM) and the op-amps. So the wait is reasonable. I am coming up on a month this week waiting for mine.Geshelli Labs is another US company making DACs … though I don’t know if they are also having supply chain delays
Of course, this is also a different dac philosophy than the Bifrost (delta sigma chip vs multibit r2r chip). The Geshelli is so inexpensive, I am just trying it for fun and hoping I like the way it sounds.
