You forgot Markus.

For all your criticism of "naysayers", you forget that they CAN hear the differences between different makes/model of kit. Some of them are very critical listeners. So, implying that they are deaf or worse is insulting to say the least. On the flip side, I can see why criticisms from someone who hasn't tried these tweaks will hurt but if they have tried it and found little or no difference in sound, it should be accepted as just that.

If the differences were that obvious we would not have this controversy.
