I see, and I read somewhere it was only the pre-Katalyst, like mine, where you could keep the analogue inputs analogue. Like you I also upgraded the phono preamp by getting PS Audio Stellar between the LP12 and Kiis — extremely satisfying.
Yes it works, I did just that after I got my Kiis but when I configured the Akurate DSM to output analog instead of digital to the Kii’s analog input the sound was much better. The Linn was first generation and its ADC obviously not very good.
