I must have missed something. I thought you'd found audio nirvana with the W3 and modded triple-flange gels. Weren't those the ones that fixed any sibilance issues for you? Can't you just get extra pairs of those if they work so well?
I might not have even noticed had I not heard the clear, transparent sound of the PFEs, so you are right, I thought I did find Nirvana, but it was really faux Nirvana. Now, with this new crazy tip combo, the harshness is greatly diminished (not gone), the darkness/veil is somewhat tamed, but I still keep wanting to take out the W3s and switch to the PFEs. Go figure. I just don't get the same sparkle from the W3s, which on paper are the far superior IEM, that I do from the PFEs. And it isn't just the clarity/sparkle, the separation I get from the PFEs outdoes the same from the W3s.
It's getting to be ridiculous, really. I am going to keep listening, comparing, but sooner or later, something has to give.
