I have the 861SE with Reference upgrade from GNSC. I still really like the looks & the sound. I don't feel compelled to change or upgrade.
As AZjake wrote - Steve is tops in pre & post sales & the best person for Wadia mods.
I also know a friend who owns an 861SE with Statement mods (what you are looking at) & he has compared his Wadia sound to other hi-end CDPs like dCS, Burmester, Accuphase, Esoteric & found that changing would be a lateral move more than anything else. FWIW. YMMV.
