I run my speakers on both concrete foundation in finished room with thin dense carpet and pad and others. No isolation needed below speakers or sub in the room at foundation level. Others yes. My sub and speakers even face the turntable within several feet and no problem. I have an Auralex Subdude I bought for the sub in another room so I use it but not really needed. Detail soundstage and imaging to the nth degree. No mud or haze. It’s a ideal setup from a vibration perspective. First time ever for me. So I am going to disagree with MC on this. No need to add any isolation much less expensive options. Ymmv but a waste of money in my opinion. Of course neither is it likely to hurt if designed to do its job well so no harm likely either other than to bank account.
Also the speakers appear to wobble on the Townsend stands in the video. Are they supposed to do that? That’s different and would definitely impact the sound not necessarily for the better overall I would expect.
