Larry, Shalom, would you concurr with my diagnosis? |
Hi Stu, "Detlof meatloaf" ? ...and meatless??? Reminds me of what in the old Harlem of the Thirtees was called a "jellyroll". Now now! Stu pidaso...you don't need to be a shrink to diagnose this as a castration-fantasy. So instead of the Bud,. as you suggest, I'd rather have a Viagra-cocktail first......
Happy cooking and listening (-:
Regards, |
Detlof you are right I am a cook and here again would recommend baking a sandwich on your amp versus making a sandwich for your amp. In fact in your honor I am having a "detlof meatloaf" = vegitarian (or meatless, that is the part in your honor...ha ha) meatloaf on white bread with mayo and little bitty (again for you) dill pickles on side. As you are aware of my methods I repeat here for the novice amp cook. Use foil, wrap carefully, lay diretly on amp or build a platform to cook on and turn up the volume. Warm the pickles seperately. Not each pickle just seperate from the sandwich.Both should be toastee and warn in center by the time the Beach Boys finish GOOD VIBRATIONS. Cheers! PS A Bud should suit your palate and complement the "detlof meatloaf" nicely. |
Yous setup is fascinating. I've experimented with PolyCrystal cones and liked them very much, but for this particular setup, preferred the spikes and ceramic combination, which seemed to give a sort of "airy" quality to the sound. I placed the ceramic plates of about a square inch each, between the granite slab and the cones (rather than spikes) underneath the amp. |
Detlof>There are no spikes touching the granite. The amp footers have been replacedwith a combo of B.D.R. "ThoseThings" bases and Vibrapods. This rest on the
granite/"Vibrapod sandwich". My speakers sit on 4" granite slabs and the stock footers have beenn replaced with a combo of Poly Crystal cones that rest on 1/2" Ebony on the granite. Where do the plates fit in? MikE |
Mwalsdor, you can try to put small ceramic plates between your spikes and the granite. You will have to experiment. If you get the right ceramic, there will be no ringing but an amazing overall clarification of the sound. Sounds crazy, has to be heard to be believed. |
I use Vibrapods between two slabs of 3cm granite for my triode amp and power line conditioner in the HT. A 15x12x6"
block of polished blk granite for the PLC in the 2 channel.
GRanite by itself rings like a bell. |
Shalom Larry,
Maple would have indeed been much better, but "real" wood is getting rare here and very expensive to buy. What I did, was to build two amp stands together with and for a friend, who has a pair of 75 kilo Gryphons, using a sandwhich of mfd, felt, lead, felt, mfd. The lead we could salvage from a defunct manufacturing plant for very little money. Since one Gryphon had to be placed very close to a subwoofer, we experimented with the felt to good effect. We placed the sandwich on a welded iron substructure, which again, with spikes, was placed on a big slab of granite. Overkill probably, but now, to quote Stu_pisado ( who certainly is not one...) once again, we are happily full of shit. |
Shalom Detlof,
What is it that you did with lead, felt and mdf? Many people are also advocating Maple as a good platform. Nice to see your post. Cheers, Larry |
Hey Stu, here I thought you could just cook...shows how stupid most of your preconceptions are. Did something similar with lead, felt and mdf and now I'm happily full of shit myself. Cheers |
What a monumental waste of time.
Vvvvvibration is not your enemy.
The whole world resonates ates ates ates...
Ever see live music on a stage.It rocks.
If you want a project get a roll of 1/4 inch acoustic lead soundproofing and sandwich it with mdf or oiled teak wood if you want. If you hear a sonic improvement you are like me,full of shit and a stupidaso. Enjoy the Hobby, I am getting ready to clean all my connections, even those I don't use. |
I used Dynamat sandwiched between 3/4" MDF. Dynamat is a vibration damping material sold at auto sound places (Circuit City, etc.). It has adhesive on one side and I used spray adhesive on the other to bond to the second sheet of MDF |
I used mdf and screwed through it 8 3" brass screws using the tips of the screws as "spikes" then placed a litely inflated 12" intertube with another piece of mdf, sand bags, my dvd player and more sand on top. Works well and can be made for $20 from supplies ate home depot |
Hey Larryr, I use two 14" blocks of heavy ceramic tile to sandwich some Vibrapods. The lower shelf is bolted to the too shallow wooden shelf of a floor to ceiling bookshelf I am forced to use.
Also, check the Mapleshade website. The have a foam and it is probably the kind of thing you are looking for. Good luck, Charlie |
You should also consider using Vibrapods as the interior isolator. They're cheap and when used in multiples can support heavy weight loads. |
Larry, I built a sandwich for my amp, works just fine. I used 4X4 lumber for the legs of the stand, and the top shelf was screwed into the legs. The top part is as follows: 3/4" BC Fir plywood, then a 1" rubber mat, then another 3/4" BC fir plywood layer for the top. The rubber mat is the kind you would use in front of a door to wipe your feet on, cut to size. The mat is solid on the underside, and ribbed on the top. I used contact cement to attach the ribbed part to the bottom piece of plywoood, and contact cement on the smooth underside of the mat to attach to the underside of the top shelf. I then used 4" screws to attach the shelf to the 4x4 feet. Voila, instant amp stand, total cost about $50. Oh, this stand holds my BATVK500 amp (which is 105lbs) without any problems at all. Kinda ugly, but the stand sits in my furnace room directly under my speakers (the speakers are in my family room, the floor above the furnace room). Hope this isn't too confusing and of some help, Jeff |
