My big problem with the advocates of ABX/DBT is the opinion based on
their claimed tests that most components sound the same and that the
results obtained by these tests prove this.

So Richard what you are saying is that if a test does not give the results
you want, it is invalid.

My experience is to the
contrary in that upgrades I have made in CD player, Amplifier and
others still to my hearing sound like upgrades and when the old
component is slotted back into the system I can hear the difference.

So what happens when you do a DBT?

I am not happy with simple a/b either as this can easily create false
positives and have found that if we spend a lot of time switching
from a to B and C backwards and forwards at the end of an evening I
am tired, I have not enjoyed the music and I struggle to tell the
difference between anything.

Been there, done that. This is a major reason for the efforts I've put into
developing DBTs.

If an A/B listening session has been
perceived a success it is most likely that either a club member
brought it with them or they are about to buy it so I have been able
to subsequently borrow it to listen at leisure at home.

You seem to be confused here. It's not the session that members bring with
them but audio components, right?

I can then
listen for longer with my choice of music. I find most changes are
just subjective, it sounds different but rarely consistently better
and is rarely worth the investment. What has however shocked me
recently is mains cables which I have always felt should make no
difference at all. I now however have a load of Kimber cables !!!

So now you have an investment in the idea that DBT *have* to be wrong.
Thanks for sharing...
