I am only interested on the High End DAC (item 3). Can you still try to arrange one more kit. If yes, I can confirm the booking by tomorrow with downpayment.
I will not consider item 2 as the DAC PCB I believe is quite different from item 3. In fact, I do have some other 1541 DAC and that is why I only want to try the top model to see the different.
I can also just take the kit if your concern is the size of the class.
Please let me know soon or we can discuss on Sat as I will join the speaker DIY class.
