Mixer interface to self powered monitor speakers

[Audiotom]

Hi

This may be in the wrong forum, sorry

I am looking for some type of interface to go from my Mini Moog to Adam A7x powered speakers (they take single ended or balanced cables)

I am also looking to add an arpeggiator / sequencer of some type and possibly a Moog Matriarch
Any suggestions? I don’t need to skimp on sound quality, build or functionality. Would rather do it right.

I would probably want this to be all analog, also with tapes out to a cassette deck

Thanks
