    Magico - Jay’s voice is perfectly natural. So, this is honest A1 sound.

Gershmann  & Diapason  are definitely on my short list 

I guess it depends on your amp as to what would work best.  if you are considering a higher efficiency bookshelf, try the Triangle. I think it runs about $9k.

Interesting fact that Yamaha was the godfather of beryllium tooling, driver dev/fab way back in the early 70s, but, apparently they are not "high end" enough for the ’elusive’ audiophile. All these "high end" names have been leeching with it since then, 50 years later (innovation? no such thing from "high end", except putting a "high end" finish on a box). Could "high end" touch the level of engineering that went into the ns5000? never...

I'm curious now why the 3000 isn’t directly sold in the US...while, the big 5000 is.

If I were to get another bookshelf it would be the Yamaha NS3000. I own the NS5000 "bookshelf" and the very detailed drivers on that are preferred over beryllium. Only issue is that if you are in the USA you need to buy from Canada.
