The two obvious and central components needing vibration control are the
TT and speakers. IME, other component also benefit but the improvements
are more subtle.
That's what I thought too. That's why my first component to get Pods was my turntable. Makes sense, right? Took some time for John Hannant to talk me into trying them under my tube amp. When I did, what a surprise! The improvement was somewhat different but at least as great as under the turntable.
The difference was with the turntable the vast majority of improvement was in the area of resonance control. A huge amount of coloration, that had not even been audible, was removed. Every instrument sounded so much more distinctively like what it really is. Audiophiles love to talk about hearing the differences between guitars, all these little sonic signatures that tell you what is what. Dynamics got a little better, details, blacker background, all that. But the bulk of it was in the area of truth of timbre.
Under the tube amp this was reversed. There was a big improvement in truth of timbre, but an even bigger improvement in dynamics! That amp just seemed to come alive with Pods! So I kept going and tried the phono stage. Same thing. The phono stage was sort of in between the other two, a more even improvement across the board, no one area standing out like with the amp and table.
Now at this point I have already put springs under the power conditioner and subs,
about the only thing left is the motor controller. This has been on cones for years. This was also the least responsive of all my components, to all kinds of tweaks. They worked, just not nearly as much as elsewhere. Now with all these leftover springs I decided to try them and much to my surprise the improvement was about as good as under the other stuff! So I played around a little more, and now it is on Pods.
It may well be that my system is so much more resolving now than years ago things that would barely have registered are now as if viewed under a microscope. For sure Moabs made a huge improvement, but there's a lot more than that. Anyway, that is pure speculation. Only thing I know for sure, vibration control, when it is done at Townshend Pods level works really good under everything.
