I had the NX-Studio standmount for a few years hooked up to a Yamaha c5000, m5000 stack (technically, a 20k stack, but, immaculately engineering). It gave a shock effect to guys who listened to that combo as well...recently sold that standmount to a dude who very desperately needed it.
I think the sweet spot for "watts" and refinement is somewhere around where that Yamaha M5000 is...for a wider genre of music.
But, here he is still talking about some lousy chip amps with Mr. Jay...doing a disservice to his own speakers @dougthebiker

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.
