6922 Amperex PQ White label... D or O-getter? Holland or Hicksville?

I think the Heerlen, Holland tubes are generally thought of as being the midrange champs and the D getters as being a little more laid back or richer.  The small O getters are a little more lively.

Of course when you try these in your system you may wonder how in the hell people came up with those descriptions as they sound nothing like that in your system.

There’s nothing wrong about talking about the sound of tubes, it’s something we enjoy doing, just as long as everyone knows that their results may vary. There are some posters on Audiogon who insist that there is no difference in sound between tubes or that new production tubes always sound better than vintage tubes, for example.

Many more people read threads than actively participate in the discussion. Many of them are people who do not have experience in the topic being discussed. So it’s always good to add the qualifier, IMHO.
