QSA Stones

Yes @millercarbon and coralkong: I’ve only tried the stones directly on top of my preamp and amp's output transformers. To my ears, very similar in effect to the SR ECT’s.

Reminds me of when I was a kid.  If someone didn't know what else to say, the response was "you're stupid".  Or as Bambi said  "If you can't say something nice, don't say anything at all".  Or the kid that always has to get the last word in.

Oh,  I put springs under my speakers and it was/is one of  the biggest improvements yet.  Cost me $100 for subs and speakers.  Clarity, transients, bass, soundstage wider and deeper.  Voices OMG.  READY, SET, GO.  Tell me I wasted my money or I am imagining the results.

@coralkong I see you are a true believer and I will respect that. I also have the right to debunk junk science. Especially when one can not even begin to validate it with science other than voodoo science. Now if you told me this was a stone that was a Ferrite core/choke and it was reducing EMI and transient parasitic signals with a pretty blue or red stone on top and could support your findings with factual data, I would believe it.

BTW you can buy 2, 15mm Ferrite Cores for $25.00 on Amazon.

@daledeee1 the thread is bout stones not $39.00 springs on Amazon. I am a firm believer in Vibration Control and that is well documented and science supports that in audio, electrical and mechanical power transmission. Vibration and it's the parasitic energy/drag effect efficiencies.

I have Springs or Suspension under all my equipment and have brass pucks on top of my equipment to help reduce vibrations.

Hunks of rock with crystals not so much. Kind of like drinking tigers blood or snorting Rino Horn will make a hard man.

So keep it in context you are comparing real engineering and science with VOODOO.

Do you guys wear power crystals around your neck to give you strength?
Reminds me of the Eastern European (no rub on Eastern Europe or the wonderful people) that sold copper bracelets on the streets of Cicero IL down by the Danly Machine Factory claiming they cured arthritis (debunked by the medical field for centuries).

Apples for apples and keep it real.

I only buy rocks made in the USA. These look like Chinese-made knock-off rocks. 

I think Everyone wants great sound and some will do (especially the gullible), anything to achieve it.Unfortunately and undeniable Great sound is going to cost big money for equipment upfront. No amount of voodoo and propped up BS gimmicks Will change that fact and/or make junk sound like a Ken Fritz stereo !! I truly feel sorry for anyone who gets scammed by some of the crap out there. And I certainly don’t have any respect for people with either no friends not much of a life or shirts with holes too small for their heads. In this world we live by science we create by science. Fluke does happen but can be explained by science.
Some of us will remember..Is it live or is it Memorex sales S… Technology and science changed that thinking fast enough. So is it regression that we find Ourselves in a gravel pit looking for rocks to put on our equipment. If nothing else it proves humour is constant.
