Merry Christmas Redheart!
Thanks for the kind words by the way. Your stands are a slick idea too! Only thing missing, is the decorative Christmas lights and the Angel on top of your Studio's buddy.
So what system are you running with your studio's?
I am very interested in everybody's associated equipment, their running with the NX STUDIO MONITORS. The feedback over time, will be invaluable, for the members and owners of this nice speaker kit, Danny's selling. So I am welcoming anyone with NX STUDIO MONITORS, to share your success stories with your gear your using alongside with them. This will really help newcomers hopefully, get a better handle on what works optimally with the monitors. 
Hehe thanks for the reminder, i filled my real Christmas tree so no deco left for the NX!😆
I use Topping PA5 amp, it's terrific! So fast and so clean, it's a marvel. Power matching is appropriate for the NX studios too. I listen really loud.
For the DAC i use Topping E50, it's connected via balanced connectors to the amp. It has a remote control for volume control so I don't need a preamp. Paired with PA5 it's ultimately transparency and details galore. I really love it. Doesn't hurt that the cost is a bargain 😃
Prior to that I also used with success the Aiyima A07 power amp, but it need a preamp in front of it . Without it, the frequency response linearity was a bit compromise being too warm, not enough bite up top.
So i tested various preamps i have laying around and landed on Meridian 861 preamp. This preamp/dac is pretty old by now, but it has an authoritive sound, with pace and grandeur. But it lacks a little bit of final detail/sizzle when compared with modern DAC. Also it's so big in size, it's not convenient...
It's a shame though, i love the remote control that can also control the raspberry pi streamer. I use Roon, maybe you do too?😊
