Need some help!

Hello All,
First time posting here, and can use a bit of help from you all. You have all helped me so much in the past.

Have been into audio for several years, and have been quite satisfied over the past few years with my setup. Recently, my wife got me a nice turntable and with all the new added listening hours, I am wanting to really upgrade my equipment. I usually listen casually (Vinyl, streaming, and my own files), but now a days I have been really spending more time listening and feel the need for an upgrade, as I feel my speakers are being held back. (I absolutely adore the focal Aria's)
My current set up is centered around a Yamaha Advantage RX A1080 receiver unit. I am running a 3.1 setup with Focal Aria 936 towers and center, and a SVS subwoofer. I also listen to headphones a lot and have a Vioelectric HPAV280 and a bottlehead crack tube amp (and some other DAC/Headphone amps that are not being used).

I am seriously considering an Accuphase E-480 or an E-4000 and pairing it with an Eversolo DMP A-8. I am wanting to look more into Roon as well. I heard an Accuphase amp a few years ago and was enamored by it, however the purchase was not feasible at the time. Plus, VU meters. 

What I am hoping to do is run the Accuphase integrated to my receiver to listen in stereo when I wish to listen to music through home theater bypass. I want to use the Eversolo as a DAC/Streamer to feed into the Accuphase (I will purchase the additional cards for phono and DAC inputs). I also want to use the balanced pre-out to connect my Vioelectric amp, and a line pre-out to connect to my bottlehead crack amp to listen to headphones. Any ideas on how to make this all work?

Much appreciated in advance.
