I don't have Orange yet but had an interesting experience with my first Blue. Because of the way it mounts it was impossible to tell which way it was going so 50/50, popped it in. Immediately noticed obvious improvement in dynamics, detail, extension. Of course being brand new it also had the standard chaotic quality that is hard to describe yet universal to anything new. Not so much chaotic as just not as coherent as it should be. Yet it wasn't long before I started to feel something just wasn't right. I want to be clear: this was not me wondering if it might be better the other way. This was me thinking it was wrong! Or at least not right. I mean really not right. Within just a few minutes it was really bugging me. Again, to be clear, while it did indeed sound much better than the stock fuse, it did not sound right.
So I flipped it around and immediately settled in and enjoyed a wonderful experience. I did flip it back briefly, easy to do on this amp, but not to be sure (there never was any doubt, directionality is night and day) but to try and get a handle on how to describe the difference. But its so wrong I can hardly stand it and actually think "wrong" will just have to do.
There was another time when I accidentally connected a really good interconnect the wrong way and was so crushed at the sound I could hardly even sleep that night, so worried I was over how awful my system had become. Next day, aha! Flipped it around. The magic is back!
Point being, I have far too many stories just like this to be so rudely dismissive as some are of these kinds of things. Of course I take everything with a big grain of salt. I am a dyed in the wool skeptic. Experience however has taught me the main thing to be skeptical about is not the result but the reason why.
That is why I love threads like this. As skeptical as I am when it comes to "why" I'm much less skeptical when it comes to "what" the people say they are actually hearing. And the more the people and the more consistent their comments the more sure we can be that what they are hearing is real- and that is something that is true and will remain true whether anyone else can say why, or not.
