I would imagine MQA through a Dirac system is one of the best possible ways to hear music right now (though I totally get why music industry people don't like MQA).
Regardless, there is a reason all these companies with their 100k speakers demo them with Dirac in the chain. I too am waiting on XMC2 or RMC1 for my Dirac fix. I'm super interested to see who does the first Unison implementation. I feel like that has the potentially to be massively gamechanging, especially for people with the crazy systems with tons of speakers and subs, since at least as I understand it, the more drivers unison can control, the better it SHOULD work.
MQA is a lossy compressed format for hi-res audio. I'd expect the audible benefits to be on the border between marginal and non-existent, since that's where uncompressed hi-res audio resides. It is not possible for a compressed format to be better than the uncompressed data. Considering modern storage and bandwidth can handle lossless, it's hard to get excited about a new lossy compression format, especially one without much support.
EQ and room correction, on the other hand, are plainly audible. Not in the same league. The time domain correction that Dirac does is not in the same league as the frequency domain correction it does. Still, I find it to be worthwhile.
While hi-res audio is worthwhile for mastering to avoid error accumulation, I don't consider it to be worthwhile for distribution. I'd be MUCH more excited about more multi-channel audio. Good multi-channel audio is awesome. I'd prefer uncompressed, but I'll take multi-channel compressed over stereo uncompressed any day.
On a related note, using any room correction system, even Audyssey, should cancel out subtle differences you hear between electronics (amps, pre-amps, DACs, etc.). So, I'd prioritize good room correction over "good sounding" electronics.
Dirac Unison sounds promising, but they seem to be having trouble bringing it to market in a consumer product. It has been stuck as vaporware for a long time. I suspect that in addition to heavy processing requirements, they may have trouble getting reliable results from it without oversight from a Dirac engineer. Also, at one point they mentioned it required an impractical number of measurements (hundreds). Hopefully they get this stuff sorted out someday. I wouldn't count on it for the RNC-1, though.
