The best $10,000 Turntable+Cartridge

Why not go for a secondhand TT and arm and a new cartridge? That way you get more buck for the dollar. The reason I'd go for a new cartridge is that you can be assured the needle is ok.
Generally speaking, a TT is a relatively simple piece of engineering that won't suffer to much wear 'n' tear. Depending on the previous owner offcourse.

As for 'the best': that is a hopeless quest, every person has his or her own taste. I love my TT, but others wouldn't spend their money on it. So trust your own ears. And make sure the TT/arm/cartridged are well adjusted...

Basis Audio + Lyra Skala

Take your time and shop around...

I am not sure how much you can believe that is printed on the web, but you may want to audition a TW-Acoustic Raven One... There seems to be mucho favorable press about this table all over the web. Check the Audio Tones website for a good review as well as StereoMojo...

Check here. I have one, and love it. I have it sitting on a sand filled wood shelf, with maple sandwinching aluminum as the base for the table to rest on. You could also look at the Stelvio, but it is more then you stated. He will drill an armboard for any for you. He also will work a package deal with you since he carries Tri-planar and Schroder.

Good Luck,
