Speaker Recommendation up to 70k

What only spending 70k....wait till you have 100k.

@emerald Update, please.

Lolol Limomangus!

Properly set up Harbeth  could run circles around speakers costing $100k!😄

[please excuse my bad English]

During the two ‘Brussels HiFi Shows’, my Harbeths demo created a stir, compared with systems that are ten to twenty times more expensive. (source, in French)

(Harbeth’s Brussels dealer)

Indeed, I attended the show, and can testify that his magnificent-sounding SHL5-based high-end system was Best Sound of the Show, and sounded better than a €80K pair of speakers two room further. But the former was setup by a master...
This demonstrate the uttermost importance of a good, experienced dealer. Online purchase is a mistake which, repeated, will bury high-end dealers alas (of course, in some region which are hifi-deserts, one have no choice than going online, I understand; the constraints are very different in some regions of North-America vs Northern Europe).

Now, *some* extremely well-chosen high-end very expensive speakers (much more expensive than Harbeths), if perfectly setup, can run circles around Harbeth though (I am a Harbeth owner). But I only know 3 or 4 of them. And only if one favors timbres.

That said, TBH, and according to his selection, I am not sure that Harbeths would fit @emerald’s demand (OP), who seems to be craving for speed, transparency and dynamics (on top of naturalness).

Ive heard zellaton. It is equisite but I wouldn't say it's better than magico. I own an m2 and had an s5mk2 before that. all depends on preference and source gear. don't get me wrong, i think the zellaton is real special but, to my ears+with my gear, the magico m2 is a perfect speaker.
