Amplifier feet and racks

Hi Richard,
     No, I've not tried them under my speakers yet. I'd need to buy another set. However, im certainly interested!

They are a lot cheaper than the G**a speaker supports that got my interest recently and led me into another one of my DIY tweaks at the end of last month.

I had my GX300 speakers sitting my wooden floor, spikes boing through the carpet effectively nailing the 27kg speakers to my floorboards. That's fine when they are over a floor beam, less so after I moved them wider and slightly back recently. Reading about the G**a's benefits of isolation for better bass and more midrange clarity I worked out a cheapish way to test if they might help me. I ordered so heavy duty gel feet rated at 30kg max per set of four, placing these under the GX300 feet after unscrewing the spikes which have M5 threads on top.

My initial conclusion was that they do make a difference mainly removing bass bloom which makes the deep bass more audible and opened up the midrange. However I found the pads tended to squeeze out from under the GX300's feet unless I got them dead centre. My latest tweak has been to drill small holes and use short M5 threaded bolts with very shallow heads (so they don't make contact with the floor) plus a couple of washers each side, to attach the gel pads to the GX300 feet. So far so good. It is easier to change toe-in now as the gel pads do not fall off. I did notice a change in character of the music after an hour or so which may reflect the gel settling.

This has made me interested in the LDA discs.

I have finally installed the Les Davis sticky pads under my Accession/Elevator and under the slim granite slab on which they sit on my substantial CD case.  I also placed some of the pads between the glass shelf and the metal frame.  The glass did ring less when the pads were installed, but one the 18KG deck was in place the ring ceased.

 

I am not proposing to switch backwards and forwards but general impression is of a likely marginal gain/improvement.  Bass a little crisper and lighter but can’t make my mind up on the mid-upper, in some ways maybe less clean on Double Fantasy vocals, maybe they were less obvious as the bass was a tad lighter and cleaner. 

If I ever have my rack apart I will put under the other shelves but am in no hurry.

 

 

Pretty much used under all components now.
