If you draw the circuit of salas's xover, swapping the cap's position 'should' have no effect as the 'circuit is exactly the same. However this is only true true if the current flowing follows the path as drawn in the diagram. In the real world each componet has a physical size and is capacitively and inductively coupled to some degree to everything around it. If the outer foil of the cap is coupled to an object that has a path to earth any RF presented to the cap has a path to earth and will cause current to flow. Putting the inductor first could prevent this current flow and so alter the sound.
Circuit diagrams can have the same problems as simulations.

Salas may have come up with a discovery, simple in execution that wouild eliminate the age old problem that when one lamp goes open circuit in a series string of Christmas lights, the entire string goes dark. Perhaps the solution is as simple as wiring the plug onto the opposite end of the series string! 
There is no ego involved. I am no 14 year old to storm my highschool with an AK47. I am experienced enough in this forum not to post stuff that will not be easily scientifically proved if I don't want mockery. I still post honest findings for reference that may help someone that actually is building something and stumbling on similar. For helping out just one, it is better to entertain a 1000 for free, in my book. They may listen with their textbooks. ABXing their paper quality.
My stuff is very well documented and measured. But if I get something outside that predetermined knowledge box, I use it. After about a 100 home and professional loudspeaker designs I think that I may be indulging in to trusting me a bit. Alnico is good, life is sensual also. I just wonder on how easily some people jump at a chance when they know me here for 6 yrs. I have taken by the hand many new people and helped them out build something meaningful. Never hidden a detail. That is DIY. It involves sharing and being bold too. Merry Christmas RCA V. Ask Santa to bring Shuguang this year. They measure the same. Sell your NOS on Ebay, you know they sound the same. The scope says so. I will reverse the tree lights for safety, just in case they might go off and he misses the the right sox.

Salas,
I was just making merry with what you have to agree is an unusual and paradoxical situation as you have introduced it. No need to take my comment as anything more.
I am at a loss why you bring up the subject of NOS with me. I did not comment on it. That said, I readily accept that NOS tubes are desireable most cases over modern offerings no matter who produces them today. In fact, I have some Shuguang 300B tubes that have served me very well, and some new ElectroHARMonix Gold Grid that are junk NIB (grid cathode short and nice expensive light show). As for my Shuguang Christmas wish list, I really would like to have a quad of KT66's and another pair of graphite plate 300B's!

Salas might be wrong and got things mixed up, possible....but on the other hand, if he finds something that does not fit into normal procedures or thinking, it is very interesting.....and it cost you noting to read and try....
It might be the physical placement, other components interacting or other things....but it is very usefull!
Thank to Salas and the others like him for the currage to bring their findings, even if the know they will get fooled by the squareheaded looking out of thier mouseholes...

Because its a great example which is perfectly paradoxical to any polytechnic school and you have been experiencing it for ever. Perfectly electrically fitting healthy tubes must not make any difference for brand or vintage scientifically speaking. So its like ''look who's making merry'' with paradoxical audio stuff. An RCA victim!

There you see, even I do not take this all too seriously! I even mock the new RCA, though I admire the accomplishments of David Sarnoff and the company he spearheaded. RCA made good stuff until the brand got sold to the French (Ah oui!) and US plants closed. Now it is a brand that markets only unreliable black plastic cr*p. I was given a modern RCA 27" television which shortly thereafter crapped out and that made me officially an rcavictim!
Its not you especially or any other. Its just the there are very many examples of coming down heavy or ridiculing people that are just making and reporting things lately. And this makes our forum poorer over time. I don't want it to become a resentful electronic textbook.
The right thing to do is to encourage and show how to revisit any test in a more controlled manner. Nobody else than fredex for example took courtesy of thinking the possible. Nobody asked how near the cap and the coil reside and at what angle. Asked for a photo? Wondered if the cap changed physical position too? That would be DIY audio.
