$35000 to $40,000. speakers what would you buy and why?

I have to agree with jsalerno277 ‘s assessment. I also

have the Lamms and have owned Apogee. Love the 

transparency but lacking bass. You may love the warmth 

of the Amati vs the sterility of the M3 but if you want detail

bass and staging accuracy you can’t go wrong with the 

Cygnus or a Giya 1 or 2. Not many are familiar with either.

I currently have the Giya 2 and may change, due to WAF

used of course. I also agree that you should
go to a show, CES or Axpona or…? Room size and shape

will also play a role in how the speaker sounds. Just because

it sounds great in the show room doesn’t mean it’ll sound

the same at your place.  It may sound better or worse. 
Enjoy the ride.

@OP Also for consideration - Marten Parker - Kharma DB7 - Kroma Atelier Jovita.

Cannot go wrong with practically any Rockport model unless you get one too large/too small. In contrast, it’s much easier to make the wrong choice with most other high end brands. 
 

If you want to save substantial coin while sacrificing very little in performance, there are good DIY options out there under $10K, including someone building heirloom-quality cabinets for you. 

I wouldnʻt buy any of them.  With that kind of budget, Iʻd pitch out everything I had and drop $16k on a set of the Dutch & Dutch 8c.   Done.

I'd suggest auditioning the Songer S1x  and the YG Hailey 3.  The Songer is a single driver active field coil speaker with no cross over and excellent phase coherence, and YG has done a lot of work on their version 3 reference line to improve phase coherence.  As the Tone Audio review says, the Songer S1x is one of the “top ten speakers you should hear before you die” kind of speakers.

The YG might be available used in your price range, and the S1x is within your price range new with the Show/WBF discount of 15% that Ken offers.  I had the original Amati Homage, and they were amazing but not my endgame.
