272/250DR - New today but eventually ultimate 2 box build/system

Just picking up new 272/250DR from our dealer (thanks to Tom Tom audio in St Albans), and demoed again the Aria 926 speakers, so just sitting over a half and deciding on whether to take the 926s home today also. (DB1i are currently at home after moving S400s on)

Looking forward to listening later today/tonight the out of the box performance, and comparing to my previous NAIM system builds.

Already though considering and looking to the future and eventually the best system build for 272/250DR as I grow into it. Taking into consideration others purchases that get mentioned here and experience of new add-ons, such as XPSDR. On my other systems I have tried Super Lumina SC and IC, HCDR and found the HCDR opened the taps somewhat letting more music out/through and the SL adding considerable sparkle and stardust to proceedings, so what similar results could be had on the 272/250DR?

I am aiming for a 2 box solution with best overall performance/price and have this in mind : 272/250DR, SL IC & SC and Sopra No1 or even No2 speakers. Thats the theory for now. Would the SL IC & SC be of more benefit that XPSDR perhaps? Plus I have Powerline but would dedicated mains supply for this system add dividends too?

My personal next step will be to demo SL SC (currently have NACA5) then SL IC (have HiLine but different connections than needed for 272/250) so this may be p/ex in for any possible ex-demo ICs than might come up.

Keen to see what others discover along similar lines.
