Yep! Via RCA from the EAR 324 output to one of the P1's RCA inputs. In this application, the P1 functions "merely" as a preamp. Annnd.. it's one a helluva preamp. I have an amazing preamp, the fully dual-mono First Sound Presence Deluxe tube preamp with Paramount SE upgrade and dual-mono external power supplies, and...I use the P1 as my pre. :thumbsup:

This configuration lets me toggle between digital music content from the Roon music server in the remote server room via optical to the streamer/DAC section or via the phono stage with the Lumin remote (which is really beautiful, BTW, and made in Austria, IIRC.)

I know the term "game-changer" is often over-used these days, but the Lumin P1 really was a game-changer for me and the qualities I so very much enjoy from my system now. Reviews often use "standard audiophile review-type" adjectives when describing gear, but I personally find the most accurate adjectives that describe the P1 are those used for fine musical instruments, e.g. those describing a Bösendorfer Grand or a Guarneri violin.
