Thiel Owners

sdecker - thanks for the photos. On my 1.6s I put a strip of aluminum at the bottom of the pocket to support the weight of the grille. Of the various felts I have tried, the best is F11 pressed wool from Sutherland. F15N (needle punched) is nearly as good and costs half as much. I have tried 1/8" and 3/8" and don't hear or measure much of any difference. Probably land around 3/16" depending on physical parameters.

Thiel Owners ,  that's a dyeing breed 

I agree that the CS2.3 baffle is cleaner vs. the CS2.4 in term of "diffraction".  I never noticed the difference before.  Maybe the motivation for the CS2.4 baffle was about the "aesthetic" appeal.  

@twoch I've done tie-dye once but fail to see how that is relevant to this thread.

@tomthiel @sdecker  OK, you now have me very curious to try a baffle treatment. But my DAC is away getting an upgrade (I'm currently rediscovering my LPs), so I'll have to let that settle in before I can do a fair test of changes to the baffle.

Beetle - FWIW, my experiments have led to a 2-layer system as having sonic synergy. Not ready for prime-time, but anyone is welcome to play.1/8" F11 (or F15N) felt plus top layer of Ultrasuede LT (lightest grade 0.6mm thick). And the clencher is covering the driver plates or bezel rings with Ultrasuede LX (stretchy), right up to the surrounds. Together these surfaces make some magic, both heard, as inner harmonic detail, and measured as lower group delay, harmonic distortion and waterfall decay. Problem is that samples of these materials are hard to get and alternatives (fake Ultrasuede or other felts) do little good. Still working.
