@captainsubtext thanks for the tag.
I have owned the Devore O/96 for a long time now, and haven't felt the speaker upgrade bug in a long time, except once in a while when a Shindo field coil speaker suddenly turns up in used market.
These speakers have that uncanny and (to me) rare combination of transparency, density, and "musicality", and the best part is that they are high efficiency, so you can use low powered tube amps (which IMO are the best kind of amps out there) -- that most modern speakers aren't designed for. So it's easy to get good music out of a variety of amps with these speakers, even SS amps work well, Accuphase is a very good pairing with these speakers.
Whether a speaker is expensive or not is a personal opinion, but at 15,000$ these speakers are a bargain IMO. Especially given how crazy audiophile prices are these days. So IMO by industry standards Devore has kept his head clear of superlative insane pricing and is still delivering the goods at a reasonable price.
These speakers were released 15 plus years ago, they haven't done stupid stuff like mk2 and mk3 etc etc, and havent jacked up the price like others, and it still has a 6 month waiting list, and used ones get snapped within hours of being advertised and at prices close to retail. The Indian dealer unfortunately has ultra-premium pricing on these speakers, so sadly not too many Devores here in India, but highly recommend you give them a listen, and if you do happen to visit Goa and have a few hours, you are welcome to drop by. Cheers!
