I had a fairly substantial demo at my local dealer with a now well run in NDX2/Supernait2 with HicapDR. This is the same system that I use except I use the original NDX, hence the demo. The dealer also ran the system with the same speakers as me, Totem Sky towers.
The only difference between my setup and there’s was speaker cable, standard interconnect as opposed to HiLine and I use a powerline on my NDX and they used lites all round.
I used my normal listening music in the same way through tidal.
Now to the point they no longer have a NDX for me to cross reference while I was there but I struggled to notice a sonic difference is this likely to be due to the few differences in cable and the acoustics of the demo room and my own living room, or memory of my own system at home.
I do also run my system on its own dedicated 10mm supply.
