Interesting update; was using the Neptunium on a studio session this morning and found that if the 1/4" is plugged in you don't run into the issue of the DI losing volume or muting even if both volume knobs are dimed, only if nothing is plugged into the 1/4" out, so truly a non issue. Sounded sick in the session, ran it through an Avedis MA5 with my 58 reissue P-bass with flats. Did the job easily! I've had the Finally, which I really liked; but this sounds more round and full and special. I don't know, the Finally was really nice, and you could get the 12ax7 sparkle out of it which was cool; but the Neptunium has a certain weight to it that I've never had in a preamp/DI (of course I've never owned a real Noble). This is 100% worth the purchase and hope it becomes a regular part of the Sushi Box line as I'm kind of floored by how good this sounds even in comparison to the Shift Line Olympic which I've used and keep coming back to for years at this point.
