Does anyone make a product currently like this mystical VPI Magic Brick?
Amplifier Enclosure Resonance
If I tap the top/side cover on my Audio Research Reference 75 SE amp, it has quite a tinny ring to it. I'm thinking that can't be best for the sound. Does anyone know of a product that I could place on top to control that resonance? It would have to be three inches or under, wide, and somewhat heat resistant.

I have had great results with Shakti stones. Not too heavy and as well as damping they deal with issues from transformers. The size suits your needs. Btw have you also tried Herbies tube dampers? Check this thread for what to expect https://forum.audiogon.com/discussions/tube-dampeners-on-arc-gear-free-tweak/post?postid=1367353#1367353 |
I'd call ARC. They do extensive testing and listening to every unit and every product. If it mattered I'm sure they'd have addressed it. They even use Litz wiring tho it makes no sense to me... BTW, I was surprised at the same thing on the top for my LS25 MkII preamp. it does have a ton of screws holding it tight tho. |
Audio Research has done a lot of testing on the effect the top has on the sound. That is why they went from a steel top to a plexi top on their Reference preamps. I have both the plexi and a steel top for my Ref 5se. The plexi top has a problem with slightly bubbling from the 6550 tube. I really can't hear a difference in the sound though. Personally, I run my Ref 5se with no top for better ventilation. I have some small leather sand bags that are used by artist. I use a pair on the top of my Ref 110 to absorb vibration. Again I really can't hear a difference between the top on and off. |
