Agree 100 percent. They did innovate with the SA6s. Maybe a little too much, as it turned out. But the idea of flexibility certainly is great with the PFEs (gray filters), as I sit here enjoying Herbie Hancock's jazz piano with the PFEs, T4 and Clip.
The Phonaks are starting to attract my attention now lol. I am tempted but at the same time reluctant as I'm already laden with top end IEMs and I've definately given up on sampling the whole marketplace now with the rate of new models and/or manufacturers that appear at an increasingly alarming rate! The IE7/8's, Westone 3's, Phonak Audeo's have all been released since November 08, and look to be of a SQ and popularity to put themselves in the IEM big boys bracket. Not only that, but Sleek, Klipsch, UE's and Shure could have new models being developed for near future release! I'm starting to realse that I can't feasibly try everything
