Hello,
Impressive system. You are going to receive lots of differing opinions on suggestions for your needs. Let your ears and market research help you in your decision making process.
My personal recommendation and experiences for a phono amp which describes the “musicality and warmth” is the Aesthetix Io Phono amp. It is to me, a means to an end for achieving musical satisfaction. It is a tubed based unit with tube voltage rectifying power supplies. The factory tubes are great right out of the box, although many have also used other tubes to achieve different levels of sound quality. The Io can also be configured for two inputs, remote, volume controls, and dual power supplies. It can get pricey with all of these options. I had tested and used Einstein and ASR before settling on the Aesthetix Io. Good luck.
