Nothing , at that price point , I just built a second audio system for the Mrs.
it has a Parasound A23+ amplifier shop,around I got a open box $1400,
AudioGD demo model $1k very under the radar,
the very much reviewed Gustard R26, better then my pontus-2/after synergistic purple fuse local dealer $1600+ fuse, Pangea sig mk2 power cords ,
Wireworld Eclipse xlr Audio cables . Older Klipsch speakers I rebuilt the Xovers
the Equinox is a lower cost cable option still very good for others on more of a budget.
It sounds like a $10k system all day .having owned a audio store and 40+ years in making system synergy . There are a lot of bargains out there
