interesting. Don from etymotic said the samples they tested showed a +\-30% variance. It sounds like you might have got one on the farther side of the greens. I think mine was probably in the middle. Or maybe I need to try my greens again.
On another note, i am going back too greens, but I was listen to some Kenny Rogers and Lionel Richie last night with orange filters and comply tips. Wow. I mean wow. It was simply some of the best sounding and most jaw dropping listening for me in a long while. No eq. Nothing.
Vocals stood out so realistically like I was in the studio. Strings and flutes and guitars just sounded unbelievably 3d and spacious, clear and distinct. Bass and drums were some of the tightest I've ever heard. The comply with the treble characteristics of the orange filters really brought out the soundstage depth and realism. These were original uncompressed no noise reduction albums. So good.
I'm going to lists to them again now with triple flange to see how they fare...
Wow +/-30% is more than I would've thought. So if there is a 2dB reduction at 3k, a +/-30% variance could mean either a 1.4dB or 2.6dB reduction instead? I can't math too gud lol.
