The ends of my steel mesh side panels are wrapped in rubber which holds them fairly tightly in the rails. Do your panels not have that?

Jim, I have a twin 40. I chose it because I have a 6 year old and a 2 year old. Both boys would be playing with my gear if I did not keep the doors locked. When music is playing at very modest volumes, I can feel substantial vibration if I put my hand on top of the components. I tried Black Diamond shelves and cones. They did not help with the vibration. They did change the sound but not to my taste. I have my DAC on a Mapleshade platform: triple point brass cones, 2" maple shelf, and isoblocks. On top of the DAC, I have 2 of their heavy hats. This has helped quite a bit with the amount of vibration that I feel on top of the DAC and I like the sonic results. Bobby, from Merlin, sent me some anti-resonance disks as part of his most recent modification for his VSM-M speakers. I have one on my BAM (bass augmentation module) and one on my preamp. They have cut down the vibration and have had a positive effect on the sound. You might try some equivalent of these. A dealer recently recommmended taking the feet off the Salamander and putting the cabinet on two Arcicci Air Head platforms. He said the more weight that you have on top of them the better they work. I have not tried these. I have read about two companies the seem to really know the science involved. They are Silent Running Audio and Nuance. SRA makes platforms that are specific to the weight and distribution of the weight of your individual components. I am planning on ordering these once I make a decision on my next amps. I am interested to read if anyone else has any ideas.
Leave all sides and backs away and just have the four posts and the boards you put your gear on. I have two 40 rags with two bridges in between. Looks terrific and offers no problem at all resonancewise. The upper board is holding the VERY heavy McIntosh MC 2000 and the lower board carries REVEL'S LE-1 crossoveramp -both around 60kg's each. Maybe that this weight affects the rigidness of the two SALAMANDER "colums": Anyway - forget about any sides or backs!
I have the Twin 40 with the mesh side panels and mesh doors. The mesh side panels don't resonate at all (they include the rubber edging). I have a lot of gear inside it including a 100 lb. amp which may be dampening the vibrations. I have it on wheels so I can move it out. The rubber in the wheels may help too. I'd like to add some additional isolation under my DAC and transport, but the transport is a top loader and requires lots of headroom so I don't think I have room for it. Mapleshade said they could build custom maple shelves to fit the Salamander rack. I may revisit that idea someday.
I have the mesh side panels to dissipate heat from the amp. I needed something to keep the dog's tennis balls out and eventually we'll have kids too. I don't have locks on the doors yet, but plan to do that. It's been a great rack. Looks great and it's easy to change the shelves. One of the door hinges came loose and Salamander shipped one 2nd day air no questions asked. We have it in our living room and it doesn't look like an audio rack.
I don't think that my mesh side panels are wrapped in rubber like some of yours. I have a lot of wiggle room between the mesh and the Aluminum rails. They just bang around. They are free to move left, right, up, down, and in and out. I don't think that the rubber does anything to stop movement on my unit. Is the rubber attached to the side panels or does it come separately?
I too have a new baby that is just learning the crawl at an alarming rate. I bought the cabinet prior to the baby, but I'm glad to have the extra protection. Thanks for the help.
Sorry to tell you, but I made a Salamander 40 knock-off for a 1/4 of the price that salamander charges.
Frame World, 80/20 are just 2 companies that sell the hardware that is exactly what the frame stiles are made of.(as well as any thing you could imagine building with the stuff)
Rather than the 3/4" selves, I used 2"x18"x20" maple cutting boards "cut down" for shelves and had the top/bottom custom made of 3" maple so the shelves are recessed as the Salamanders are. The mesh can be had had numerous places(mcmaster carr).
I put a Rubber snubber tween each shelve and "mesh" to deaden the "rattle", I would try "Home- Lowes" for a rubber snubbers to place between each shelve and the mesh
imagination is endless, j
I have a Twin 40 and purposefully ordered it without any doors, sides, or back panels, which I knew would just resonate. Next I am replacing all the corner shelf supports with the heavy-duty bracket-type supports to strengthen the overall structure by adding crossmembers. I got this rack for its appearance, adjustability, capacity, accessability, and mobility (including the Saturn wheels), not for its rigidity or inertness, which are always going to be just so-so.
