New TOL A&K DAP : the AK Ultima SP1000
Dec 19, 2019 at 1:04 PM Post #7,623 of 9,406
Just tried this on my SP2000 and says no update. Running 1.16CM.
Is there any noticeable sound difference between 1.13CM and 1.16 CM on your SP2000? Please share.

Great!
Which firmware version are you using?
1.20CM and have no willing to update.
Tone generator for testing a headphone, Chrome helps me enter Youtube on my Spk, Neutron for my taste...
Also UAPP on Spk is my need

Hello.
Do you know if it is possible to downgrade the AK to the previous firmware?

Shutdown unit then press+hold vol+ vol- power untill "A" logo displayed then release holding after 2s.
There is Menu display then.
You need a usb/card with firmware file content
