At this point I’m really only wanting to hear what $100.000 can buy and sound like.
It’s probably a fair assumption that anything reputable you buy for that money should be very good, in which case the end results will be determined largely by personal preferences (everyone is different here) and how well executed the system is end-to-end, including room, no matter what path is chosen.
Main thing is to enjoy what you are doing at all times, both along teh ride and once you reach the destination.
Were it me making that investment, I would be probably be seeking to have a large room that would be amenable to a nice pair of mbl omnis and go from there.
In lieu of just the right room needed for best results from full omnis like the mbl, I’d probably either stick with my large Ohms, or might consider splurging on a pair of KEF meta blade 1 or 2s. I might even settle for a pair of KEF Reference 3 meta for ~ $15K and optimize for those upstream. This is actually something currently on my radar screen, but so far I can’t justify the additional investment and overhead of another pair of fairly large and heavy speakers. I’ve actually downsized in recent years and when I compare what I have to that ideal, I find I am in a very good place for a lot less cost and operational overhead.
Cheers and good luck!
