Has anyone else confirmed this I believe Joe may have agreed with this comment but just wondering if others have the same experience as I would not want the treble to get quieter even as I like the rest of changes ElWappo noticed.
We also noticed there is a slightly recessed upper treble, as opposed to rolled off. As an example, we both noticed this on a lossless live version of Hotel California off The Eagles Hell Freezes Over album, around 3:17-3:40 or so. The acoustic guitar in the background is slightly quieter on the customized SM3 than on the stock SM3's, but the details are all still there so everything is still resolving. I wouldn't describe it as less bright, as tonality has not changed, rather just the volume is slightly lower.
