I’ve got the NX-Oticas; built them with some skilled help.
I would not trade them for any other speaker I’ve heard and yes, I’ve heard the Magico M9s pushed by ~$750k of top-shelf electronics.
My intro to GR was the double trouble sub kit, which i’ve been using with a variety of speakers over the years....Built out the NX-Studio kit just out of curiosity (not like i had the space or needed another speaker in the house to enrage the spouse), A/B’d it against speakers that costed/costs magnitudes more...the value proposition with these kits is just hard to believe. They tend to scale up really well as the front end electronics get better as well.
Sounds like the OP has a good thing going with his larger room, choice of front-end electronics and the bully.
P.S. Danny’s only sin is continuing to tweak certain speakers from some other brands that some dudes found depressing (continuing to ship them to GR in pursuit of happiness again)...tends to get the salesmen for such depressing speakers up in arms, "How dare you make him happy again???!!!", sez the sales guy.
