Best speaker in the US $ 30-45.000,00 range

If I had that much money,I wouldn't be asking people on an audio forum how to spend it.But hey,that's just me!!

Since you are considering Verity, I strongly suggest the $30K Verity Amadis instead of the $16K Verity Leonore. I have heard them both and although the Leonore are very good, the Amadis are incredible. Other than the Shindo Latours, the Amadis are the first pair of multi-driver speakers that I prefer over my Silverbacks. The Shindo Latours are still the best speaker I have ever heard, but they recently went up to $55K a pair and are well above your stated price range limit. Mine too, unfortunately.

He is not asking how to spend his money.
Well, I was close - you may need to increase it to $55k.

If you have heard the Magico V3 and like it, I would consider holding out for the new Magico Q3 which will be launched in January. But I agree with what others have said. Listen to all of these at dealers and narrow the list. Then listen to the top 3 or 4 in your listening room to know for sure which is best for you.

Consider the new Vandersteen Model 7, the Magnepan 20.1 supplemented by one or two JL subwoofers according to your room and budget.

Finally, before you spend that kind of coin, give a listen to the B&W 802D, relatively cheap at $15K a pair, but competitive in that price range.

I have heard all of these speakers. My personal favorite is the Magnepan 20.1 + JL subs, but that's anything but a petite setup.

I also am partial to Sonus Faber. Excellent tonal balance and always musical presentation with a deceptively high level of detail that's never irritating.
