@oldhvymec. Funny thing is I have tried all this stuff, Shitaki Stones, Petoskey Stones, Tuning Sticks, Crystals and none if it did anything, Did not even make my wallet lighter as I sent all the crap back and only bought this stuff from vendors with return privileges.@jerryg123 Fair point. There is some twisted logic in this thread. If someone tells me they have tried hitting themselves on the head with a hammer and it hurts, then I do not have to do the same thing to have an opinion about hitting yourself on the head with a hammer. Likewise the converse if someone tells me it feels great.
Here is the other thing I do not see this stuff being sold the real high end audio dealers.
If a product has value, it will be sold at reputable dealers, reviewed in the trade magazines and publications, and most importantly, there will be competition from other companies to sell similar products and take advantage of the economic laws of opportunity and market share.
Of course, shills will state "You have under-developed listening skills" , "Your system is not resolving" , or the old and tested "They require system synergy with components you lack".
Don't comment statements apparently are needed by the shills helping someone sell something. One doesn't need to buy expensive rocks to have an opinion about said rocks.
