Post Subject: An interesting observationPosted by N-set on: 2/24/2021
I needed to lift my PP1500 off the carpet as it had not enough air circulation. Somewhere in the PurePower materials I read that vibration isolation is advisable, so I decided to kill two birds with one stone. I've got a set of nice metal roller footers from a Polish manufacturer and a friend of mine as putting one of our big isolation platforms seemed like an overkill. I did not expect anything apart from a better cooling, but anyway I did a quick reference listen before the installation of the rollers and afterwards. Well quite to my surprise, there seemed to be some moderate-but-noticeable change in the sound: deeper and more articulate bass, better dynamical contrast like if some veil was removed. These are the typical effects of a proper vibration background cleaning that I've heard hundreds of times. Unless I was hallucinating, as the test was quick and I have zero interest in repeating it (unless with one of our big platforms but that later), PP indeed seem to benefit from vibration isolation. the interesting twist is that the test was performed on headphones so the PP was not embedded in an acoustic sound field, just subject to structure borne and its own vibrations.
