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

I second Buconeros advice. Also dont forget about the Wilson Sophia 3's just because of their lower pice tag...they are worth a listen.

Yeah, get them all into your house at the same time and have those guys run around with different cables, amplifiers and other damn things. But maybe you'll have to increase it a little to,say,$50k.

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.
