Speaker Recommendation up to 70k

They need a lot of power, but MBL are unique and amazing.
The most real sounding speakers I ever heard are Rockport.

I would go a bit differently here than the direction I assume you’d prefer; if "workman" or industrial looks doesn’t bother you too much, and you can rid (that is: relieve) yourself of any want to "experiment" ad nauseam with amps and expensive cables, I’d choose a pair of actively driven ATC SCM300 ASL Pro:

These are great speakers by any measure and will go up against most anything out there, period. No - and let this be said once and for all: you don’t need a huge sized listening room to make these sing. I’ve heard them in moderately sized spaces, and they sang wonderfully - in the lower octaves as well.

One of the best midranges ever build, twin 15" per side for authentic LF to lower mids, ATC’s recent and self-developed (like the rest of their drivers) 34mm tweeter, and not least active configuration all superbly implemented into a sonically coherent whole. This is a proven design for years in the pro field, build like a tank to last many years - even driven hard and continuously.

Don’t bother their pro origins as anything that’s claimed to fall back negatively on their sound in a domestic environment. That’s just B.S. Anyone with a pair of functioning ears and a minimum ability to openly and honestly assess sound quality will acknowledge the serious merits of these active speakers.

Forego any fancy, finish luxuriating and overly expensive passive "high-end" speakers, and step off the merry-go-round with a sensible, active solution like the above. That’s my advice.

Be prepared to make adjustments, regardless of speakers chosen. You are seeking speaker following all the rest of the system. That is not ideal, but it is part of the audiophile experience eventually. Do not hold your hopes up so high that if it's not sensational, you will be disappointed. I could make a system with shortcomings with any of these, or a seemingly flawless system, if I had control of the components and cables selected. But, when given one set of gear preselected, there is no telling which outcome would transpire for any of these transducers.  No one here can answer your question, and if anyone claims to, I would not heed their opinion.   :(

A bit more information such as what speakers you have owned, or currently are using, as well as your preferences in sonic attributes, would assist the community in making recommendations.  

well money is relative, $70k is not a lot of money to some people and to others it is unattainable. 
Anyway people really need to know amp your using. Can it handle a low impedance hard to drive speaker?
