Amp Stand for Heavy Amp on Wood Floor?

[Puma Cat]

The 4" high density EVP's necessary to support the (90+ lb.) weight of a Pathos amp between two boards are $200 ea. x four which is roughly 10X the cost of the Herbie's Big Fat Dots. For me that takes it out of the DIY price range. I would opt instead for the superior Wellfloat platform or Delta footers.

They're more expensive, to be sure, but they are more effective than the Herbie's products. The VibSensor data plotted in JMP data supports this. And, as we say in science, "the data is data".

Putting them under my REL subwoofer was absolute revelation as they made the entire room signficantly quieter.

I’d welcome any thoughts on a DIY stand for my Pathos InPol Heritage on oak floor.

Current thinking is two IKEA APTILIG bamboo boards with Herbie’s Giant Dots between them and Herbie’s Giant Gliders between the floor and bottom board for ease of movement and further isolation.

I don’t want to break the bank on amp footers at the moment and so am thinking to keep Pathos footers or use OREA Bronze underneath amp.

I realize there are much more effective and costly approaches but this is where I am at the moment.

. Also thinking one or two 1-1/8 granite slabs instead of the bamboo but I’ve read conflicting comments about granite.

TIA for any thoughts or suggestions.

Any opinions as two whether 1-1/4” IKEA bamboo boards or 1-1/8 granite plinths would serve as a better amp base? One or two. If two, Herbie’s Giant Dots between them. TIA

Personally, I'd use the IKEA bamboo boards. Granite can ring.

Bamboo. Granite rings.

I have chosen to use mass and control the resonances through tuning by ear.

That steel looks pretty classy, PeterA, not to mention the wood beneath.
How much does the steel weigh? Is that an Aleph 3 for scale?

It depends a lot on thickness and dimensions of the board. IMO unless we use an accelerometer connected to an audio analyzer we never know the real ringing performace of a board.

Thank you ICU. The polished steel plate weighs about 120 lbs. Yes that is an Aleph 3. My main amps are Lamm ML2s.

Always love that look Peter. Proportions are really beautiful and balanced… not that I’m a design tragic or anything lol PS even nicer with the Lamms

Bamboo. Granite rings.

Thanks for all the input on my DIY amp stand. Waiting for Herbie’s Giant Fat Gliders to place below my IKEA boards. And lo! I discovered 8 Orea Bordeaux in my storage. So they will go under the Pathos. Will be curious to hear effect, if any, on my system.

Thank you Graham. The stands were designed for the Lamms based on what I learn from earlier experiments. Here is a version on deflated Vibraplanes. 280 lbs of steel on birch ply.

The progression to the Lamms and the tubes with the structural cool of the steel and the organic warmth of mahogany below it is where I’d happily stay as well… looks beautifully settled.

I still have some 2 inch thick slabs of Queensland red box which I bought 20 years ago that had been stored in a timber yard up north of here for over 60 years before that.

I’ve used about half of it for a dining table in the last house but am a bit inspired more recently with your approach to use the remaining slabs for my gear and bring in a layer of polished stainless as an additional constrained layer above.

Great looking table and view. Your plan for stands is good. What material you use and where you locate it between the steel and wood matters for the tuning.

Beautiful table!
If you do decide to use some of your remaking stock for equipment stands, may I suggest that you start with just one or two and see how you like them before cutting up more of the wood. All wood sounds different and you may or may not like how this particular wood sounds in a support platform.

There is some trepidation for me because while that wood in the slabs is beautifully figured more importantly it has great sentimental value for me. I bought it out of an inheritance when my grandfather passed. He was a carpenter and builder who built houses in the modernist era and he was the inspiration for the house that I designed in the village on the lake that he used to visit for holidays when he was a child. I clad the house in recycled red mahogany shiplap and it is the kind of material and detail that we both really loved.

Stunning!

 

[JackD201]

Has anyone compared directly in his own system a Symposium Acoustics platform to either a CMS amp stand or an HRS amp stand?

Yup

You know where I went SRA was the close 2nd. My problem with SRA is that it is more equipment specific. Nothing to do with its performance for the model it is spec'd for. They are excellent and that is coming from a competitor. That is an expensive proposition for a distributor or dealer like myself that demos many different amplifiers. They were literally in a dead heat then CMS went modular and incorporated the frame and contact point changes that made them more, shall we say, long term keepers for as long as the new amps fit.

Holy heck! What a beautifully designed home!
