Astell & Kern SP2000 vs Lumin D1 with MCRU LPS

I currently have a Lumin D1 with MCRU LPS connected to Audio Research SP17 which goes to CR-1 and finally Revel Rhythem2 and MC352 powering CM10 S2. I just did my car audio system and will be purchasing an Astell & Kern SP2000 to Mosconi 6to8 aerospace to MCC404 powering Utopia No 6, JX360/2 to Focal PC165, and MCC302 to Dynaudio Esotar 1200. My question is now that I will have SP2000 can I get rid of my Lumin D1 with MCRU LPS. I also have a roon nucleus in my home system, am looking to add hotspot to car and see if I can get a Nucleus for car as well so I have Roon everywhere. SP2000 and D1 are both Roon Ready, MQA compatible, etc. Any advantage to keeping Lumin and not just bringing SP2000 with me and using it everywhere? Get some top tier IEMs and have it for portable and perhaps one day office too? Thanks
