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

I wouldn’t look at any of those speakers.

Also, never go out to a dealer to listen to a pair of speakers and buy them on the spot. The ONLY way you will know if the speaker is any good if you play it in your room, using your electronics.

You said you have a medium size room so I’m guessing around 16’ long, 12’ wide? If your room is anywhere close to this size, the biggest woofer you should look at are 8” or smaller. Most people, even most dealers at audio shows, try to place too large of a speaker in a medium/small room, that’s the worst thing you can do. I just moved from a 27’ room to a 16’ room and had to downgrade my speaker size. My new towers have multiple 6.5” woofers plus, the best thing I did was to get the rel t7x subwoofers. 

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.
