fuses - the $39 ones or the 85 cent ones

"First off there is an EASY to discern difference at times hearing these fuses" There lies the rub. You are right though in that $39 is not the issue, or a reason in itself not to try it. I know if I had not already done so, and read this thread, I would try them and end up pleased, or have a good laugh.

Running off to work, BUT...
I agree, at first glance with Audiofeil.

I hear what I want to hear, just like my car runs better after a washjob or an oil change.

How else could the 'rocks' get positive reviews? These discussions verge on religion, a place where I won't go.

As for DBT usefulness for drug tests. Yep, but so much more. This technique is widely used.
You COULD get such a test together for Hi-end, but the loops you need to go thru make it a Practical near-impossiblilty.
Stuff like, 1. who gets the good seat? 2. What is the reference system....couldn't get 3 people to agree on THAT.
3. Who has time to organize such a test? 4. Where are you going to do it? 5. Who will do the Experimental Design?
6. Who will crunch the numbers?

So, while audiophiles have huge emotional reaction to DBT, they really have little to worry about. The chances of actually getting such a test off the ground is ZERO.
On the other hand, Cables and I/Cs to make a difference. I have heard it myself. Usually not for the better, once you have found your comfort zone.

Have fun with it. It's not the end of the world....or IS it?

Pubul57 has it pretty much down to basics.
For any 2-way test, the basic chances of a choice being right is 50:50. There is some more match to it, like levels of significance, but that is the basic idea.

Magfan, obviously you heard differences yourself with ICs and Cables because you wanted to. At least by your logic.
