Ok,I'll bite.
What would you choose?
Consider a room at this size and the need is lifelike SPL (so 120-130db SLP peaks at least,as this is what Genelec describes as such),care free operation,top pre and after sale service (very important) and probably a very good reselling value.
Looks at your disposal.
ONLY one MLP.
I'll bite in return.
But where are you getting the SPL requirements from? I personally listen at mid 60's to low 70's db at distance, and sometimes mid to high 70's db at distance. I don't think I listen to beyond 85 db at distance, at least not in the last 10 years. Even when I was younger, I don't listen to music that loud, it hurts my ears if I do for a prolonge period. But that's just me personally, so I will list what I would buy at my preferred listening volume level.
I could do a D&D 8c or a Kii 3 with BXT and call it a day.
Or I could do the usual suspects of speakers, say Revel, to Ascend to KEF, to Perlisten, Perlisten which is what I have now. I would probably do multiple speakers so I can switch things around but since money is no object, one of the speakers would be the Perlisten S7t Limited Edition, MSRP $30K.
I would definitely get dual subs, it can be the same speaker brands as listed above.
I could do dual amplification or dual bridge mono if I so desire the level of SPL. I would be looking at Dutch and Danish Class D or the Benchmark, if I care to chase SINAD, but I also recognize it's likely below my hearing threshold, so I could find a Bryston. I personally like silver casework, so it would never be a MacIntosh, not to mention I don't like their design, way too old fashion looking for my personal taste. Though I do like the Japanese vintage look. I'm actually in the market for a new amp and I am seriously considering the Apollon dual mono Hypex NCx500.
I like 430mm wide casework, all the Chinese brand DACs are kid's toy-like desktop form factor, so I will probably look at the Okto Research DAC, but right now, I don't have a perfect DAC I would like to buy when it comes to aesthetics.
EDIT: Also, the claim that Ultra low THD+N is not necessary, say with 3 zero's after the decimal. I argue against that, my pet peeves when it comes to amps, is the hissing noise when there is no music playing. Pause your source, crank the volume up all the way, put your ears next to the speakers and hear that hiss. That really pisses me off, despite I will never hear it from distance and I would never do that in practice. But there should be no excuses for such hissing and that is a design of an amp with poor noise floor. My current DIY Hypex is dead silent. Even my SMSL with the infineon Class D is dead silent. So for me personally, an amp with THD+N of 3 zero's or more is a must.
