Tweaking a highcap with mass-damping case or cones?

Posted by: Jaybar on 30 June 2001

I have begun to experiement with Walker resonance control disks. These are mini pucks (2" in daimeter by 1" high). The outer containing ring is a brass alloy with the center lead. Placing one on-top of the high-cap which powers my CD5 makes the sound clearer and ALTERS PRAT. My first experience is positive but mixed. Has anyone had positive experience with this type of mass damping or adding footers?

I tried some BDR cones under my Hi-Cap when it was powering the 102. I liked what it did (clearer sound, more weight), but these changes were very small. In comparison, using a sheet of MDF support by three ball-nutters (a ball bearing sitting in a small nut) was better. It gave many of the same benefits, but the music made more sense.

Setting my SNAPS2 on a Mana Sound Frame made much more difference than either of these other methods with the Hi-Cap. (BTW, it was the "difference" that was greater, and not the overall performance. A Hi-Cap is much better than a SNAPS2, regardless of supports.)

The Zoethecus rack has 1" thick MDF shelves with a zorbethane iso-damping system. It is maple filled with sand. I have not tried the Z shelves yet which are constrained layer damping. In my room, I have not been impressed with metal frams stands. I did have good results, however with Symposium roller-blocks which use ball bearing issolation, but they drove me crazy If I had a Naim only system, I might consider Mana, but Zoethecus is the only thing recommended for Soectral. It also works very well with my limited naum gear, but it is very expensive.
