Polished granite looks beautiful and I started off by mentioning that I was a.o. considering two 18x12x3" granite surface plate machinist tool (they are fugly but not that noticeable if they disappear somewhat under the amps). I intend to implement a "virtual earth" where upon "an energy diffuser" platform like the Symposium Svelte/Plus/Ultra will be put. The mono blocks can either sit directly on it or coupled through footers (depending on the budget and availability Symposium Rollerblocks HDSE, Rollerblock Series 2 or Stillpoints Ultra SS).
A 100lbs wont ring but my back can't handle that anymore. The whole family has been put to the limit -noticed my pairs of not-so-featherlight-speaker sets ? Guess who helped them setup,,,- so I won't involve any of them helping me unless it is a matter of audio life and death.
But I could also go the route w/o mass loading. Peter of Symposium suggests that may work. BTW Peter is a very helpful person, lightning fast email responses! I spoke only once to him several years ago and ended up with the Svelte Shelves and lots of footers. There are of course better ones like SRA but not in my budget range.
I did more reading as I thought if resonance is the issue, why not see what speaker builders are using besides wood that is relatively cheap and easy to work with. Dupont Corian came up. Just sent off some requests on Ebay to inquire for 18"x18" plates custom made in black. I will try them at least for upstream equipment.
/Hew: I may consider DIY but like to stick with finished product for aesthetic and resale ease reasons. Definitely will try some DIY for the home theater system.
/samhar: please also see my system page. The mono blocks sit on Symposium Svelte Shelves with BDR cones/puck as footers directly onto the cabinet. The upstream equipment sit on a cabinet shelf, one indirectly through also a Symposium Svelte and a double stack of Rollerblock Series 3 (DAC), the other on a maple butcher block and Stillpoints Ultra SS (CDP).
Unlike most of you, where swapping out a cable, footer, even an isolation platform is easy, I have to disassemble everything in my "A/V niche" if I want to get anything near the mono blocks so trying out something under the mono blocks happens in reality once every blue moon and I use that opportunity to clean contacts, spray anti static stuff, check my BMI, etc.
Hence I need to ensure to have the best and most practical strategy possible.
So now we have a lot of great input, the larger question is: do I need to mass load under my amps? Should I haul two 60lbs granite slabs or some 18"x18" pavestones? Please vote now...
FYI The cabinet is relatively well put together and has a mass of at least 200lbs (empty, estimated 350-400lbs with contents, I have removed stuff that "ring" during bass passages) but there is a drawer (not visible in my systems page) directly under the "A/V cavity" and I am not allowed to fill that one up with sand...arghh..
Keep your comments flowing...
