These are not "just damping devices", as stated by the audiotweak. They also help ameliorate field energy, a real issue in almost all systems, with some being more sensitive to this than others. As someone pointed out Mick's pre is made in the Outback 'down unda', in an area with much less rf saturation than most of all the US cities. I would think it wise to let each listener make his or her own decision.
Also, as an observation on the comments of theaudiotweak, nothing that I have ever heard sounds like real music dynamically or otherwise, because of the enormous problems in the recording process and the limitations of playback capabilities in all gear, from speakers to amps, and throughout the entire chain. Also, I would personally like to hear any system anyhere that offers "all the dynamics contained in live music", as stated by Theaudiotweak, but no such thing exists at this point in our technology.
That aside, if the idea of cleaning up your system from these field effects and microphonics, appeals to you, and don't mind trying some fun project, and you need help building it, you can email me.
