    I couldn't settle back down with old flabby bass, so sealed cup grills with micropore tape.

    Switched to 95mm pads because smaller pads are too uncomfortable for extended listening (85mm pad foam is narrower with less surface area for spreading pressure).

    Like with the Yamahas adding more damping makes more apparent the treble peaks. In exchange I get faster transients and tighter more extended bass until eventually bass starts to stiffen and fall off. Another side effect of damping is shifting upper mids dips. The T30 treble peaks are not problematic yet, so I'm going to see how much more damping I can add before it does become an issue. Before hadn't explored too much damping limits because I removed that front felt filter circle and it made treble peaks unbearable. Now I can go full ahead damp.

    Next, seal cup grills with electrical tape. Front baffle still tiny bit leaky though so not a full-seal which is probably for the best.

    Sealed grill. Extra damped bass is extra interesting but now there is a 2kHz hump. Not sure if its overdamp or reflection. Didnt expect to work anyway - just curious. Had to switch to high gain on Vali2 to get measurements. You can see the micropore left from yesterday’s experiment which sounded pretty good.

    I just noticed user bucketinabucket from HF is @Ariamella here. Aria sold me their spare RP18 (HF classifieds). Hey!

    I just messaged @purr1n for his participation in a vintage ortho tour. Headphones provided by me, @dBel84 , and @rhythmdevils (?). Maybe you'll see your RP18 Aria. @Vtory , @Hands , and @cskippy also welcome. Tour still to be organized but please contact if interested aforementioned users. Sorry others, keeping this tour concentrated to most prolific reviewers and measurebators @Merrick you can at least get my stuff afterwards and keep YH-1 if you like - I don't want.
