Any phono preamps with volume control?

Aesthetics Io Signature has one, Graham Slee Accession as well.

I would suggest using the SYS with short interconnect cables between it and the Mani.That would also provide switching between TT and streamer.

Also the Quad 24p. Not dreadfully expensive and designed by Tim deParavicini!

Since you appear to be streamer-centric, another approach would be an Auralic Altair G2.1 or G2.2 streamer/DAC. Both have phono inputs to a decent-sounding MM phono stage, a line level input, and of course the streamer function. The volume control is high quality. One box replaces three; all functions are selectable from any programmed remote. If you want to run an MC cart, you can get a step-up transformer. I’m considering a second residence in a place where apartments tend to be small, and this is what I’d probably do. Add active speakers like ATC or PMC and you have a respectable minimalist system. I know that’s not your goal but the Auralics are excellent streamers in themselves (I have a G2.1), and replacing your current streamer with one would answer your need and let you ditch the preamp, too. Just a thought.
