Walker Valid Points or Mapleshade Footers for preamp?

I am looking for place some brass cones under a tube preamp. Is one product better then another for this purposes or does this matter more equipment with more moving parts?

I have tried over the last few years, Stillpoints cones, Finite Elemente Ceraball (original), Finite Elemente Cerapuc, Cardas blocks, EquaRack MF-1 footers and HRS M3 platform.

I posted my impressions on these devices in this post:


All the isolation devices I've tried work well. Some better than others. So in my experience, each one of these footers or platform is an upgrade from the stock feet that came with the audio equipment.

From the isolation devices I've tried, the HRS M3 and EquaRack MF-1 footers are much more efficient at controlling vibrations and resonances than the other ones I have.

I currently have all my audio equipment on a credenza. I have the HRS M3 sitting on it supporting my turntable. I can play a silent track on the turntable and knock hard on the top of the credenza and I hear nothing on the speakers. That's how good the M3 is.

I conducted a similar experiment with solo violin music playing on my CD player. This time with the EquaRack footers. Again, I heard nothing being transfered to the audio signal.

I currently have EquaRack footers under all my equipment, except for the turntable. With these footers, everything is tighten up and I hear more of those micro details that tend to get lost in reproduced music.

I still have footers from Stillpoints and Finite Elemente. And I still use them from time to time, but just as a reminder of how good the EquaRack footers are by comparison. I also keep using the Cardas blocks: to set up the VTA of my tonearm.

I hope this helps.

Best Regards,


I recently tried three Acoustic Revive RIO-5010 clear quartz disks under my H-Cat line stage. I must add that it already was on a level 5 Mana stand with an Acapella isolation base using the special pucks between the unit and the isolation base.

Simply inserting the RIOs between the pucks and the unit resulted in such a positive change that I was shaken in my commitment to the Halcyonics base, but then again I have only been able to afford two of these and my line stage isn't lucky enough to be on one. I really don't want to hear what it would sound like on a Halcyonic base.

These quartz gizmos are just unbelievable. The dynamic jumped and the precision of the sound stage was just scary.

I don't know what they would do under other units or between my amp and the Halcyonics. In the last case just because I don't want to know.

Honestly, I don't know why these have such benefit. I have found some instances in which the RIO-5010s do little or nothing and really hate trying them everywhere if it is more than just placing them on top of components.
I have tried both the Valid Points and Mapleshade Footers under all of my equipment (including the pre-amp).
The Symposium Rollerblocks were far better in all respects. You can pick up a used set on Audiogon in the $ 225 - 275 range. Make sure you get the grade 3 balls.
The biggest effect I experienced was with power supplies and power conditioners but all pieces benefited in a big way.
I hope that helps.
