This is a review and detailed measurements of the Eversolo DMP-A6 Streamer and balanced DAC. It was sent to me by the company. I don't have the price but see it on sale for US $850. The DMP-A6 design is absolutely gorgeous. A large, high contrast LCD allows it to show realistic visualizations...

This would cover most of your needs. Streamer, Roon, digital inputs, remote volume and ready to feed your power amp. What is not covered is analog straight thru bypass and no phono.
I'd suggest something like this be added for phono:
This is a review and detailed measurements of the Focusrite Scarlett 18i8 Version 2 Audio Interface (analog to digital converter). It is on kind loan from a member. The current version seems to have moved to version 3. Assuming its cost has not changed, it goes for US $297 with free shipping...

Amir did not recommend it, but it will present you with no problems. You feed your Fosi phono to it, and that can be output over SPDIF coax to the Eversolo. It has less than the 105 db SINAD, but it has enough SINAD you'll be well beyond what you can get from the Fosi phono. You'll need to set it up with a computer over the USB, but it can be operated stand alone with no computer after that. Set levels once with the Fosi feeding the line inputs. An RCA to XLR cable will allow that.
You'll have your Eversolo at the center of things remotely controllable. It will get SPDIF in from the Focusrite so you'll have your phono. It will get the optical Toslink from your CD player. It should do everything you need. No analog bypass, but you'll never hear a difference vs one anyway.
