In Reply to: RE: Tube Preamp Vibration Control Suggestions? posted by JoshT on June 09, 2017 at 12:20:08
Are you experiencing microphonics on the RP-5?
On ARC gear I just leave the factory rings on the tubes. For other brands I've used inexpensive tube ring dampers bought off Audiogon. I'm not sure what these were made of exactly but they held up well, didn't melt, and remained pliable over years of use.
I've used Sorbothane feet and relatively inexpensive Vibrapod isolators as well as those square wood/cork blocks with ribbed rubber pads on each side.
But truth be told, I never had any indication that I needed these accessories. I added them as a precaution and for peace of mind.
I believe the main thing is to keep the preamp away from the speakers if possible! That has been my experience but I suppose some preamps (and some tubes) are more sensitive to vibration and microphonics than others.
Nope. Not hearing anything. Just for peace of mind and because I've been playing with vibration control generally on this system the past few weeks. Like you, not sure I really need to, but having fun experimenting.
"If you are the owner of a new stereophonic system, this record will play with even more brilliant true-to-life fidelity. In short, you can purchase this record with no fear of its becoming obsolete in the future."
