"If the above tests show that people can consistently hear differences between speakers, cartridges and even amps and preamp, then this would be a mark for the double blind testers."

I am only suggesting that if people couldn't hear a difference between speakers in a double blind test then maybe the tests are not accurate for this kind of thing. That's all I said. I have no idea how a DBT would come out using speakers. Don't be so combative and try understanding the post before you jump to conclusions.

You say...

"I think that "if people had trouble telling apart even speakers, cartridges and preamps using blind testing, this would help prove the point of view that" there were no audible differences between the things being measured."

So the test must be accurate no matter what the circumstances? So if in a double blind test people could not tell the difference between water and wine then there must be no difference?

Makes sense to me.
