I’ve got the NX-Oticas in my listening room with about $50k of power conditioning and 1st rate cables. Only have a $25k digital front end, but my rig sounds MUCH better than Danny’s. I made some of Danny’s cables and they degraded the sound significantly. Great for modest systems but you don’t want to subject Danny’s NX series speakers to them.
I’ve got a very good 300B integrated amp driving these and most of the folks in our audio club are shocked at how good the SQ is with only 9 watts.
