"What are you guys talking about?" Tubes are like every other component in the chain-except more so. Virtually every person you ask will have their own opinions, so it's ridiculous to demand to know 'the best'. Do some research, buy a set of tubes, listen to them for weeks, attempt to isolate what you do/don't like about them, do some more research, try another set. Etc. Yes, this process can take a long time. Years even. Fortunately, it's not torture-unlike, say, a crappy, ear-bleed cartridge, tube differences are generally subtle enough that, unless something's horribly wrong, any set will be listenable. It's all about nuance.
And one other piece of advice-drop the dickhead attitude. People are giving their time to try and help you, whether you know it or not.
