I've used that Dehavilland/Chimera list as a guide and found the results spot on, although not complete. The VT-231 Tung-Sol, round black plates have it all, air, dynamics, 3D image, and a premium price.
As stated above, Sylvanias are neutral with airy highs. These are the go to tubes for clear top-end extension. All the RCA's have a classic warm presentation with open sonics and excellent soundstaging. Amperex Bugle Boys have airy highs with amazing 3D imaging.
There are so many good tubes on that list, try to buy from a dealer who accepts returns or exchanges.
A good source of tube info and a very good dealer is Brent Jessee.
