"All vibration control devices.." again this would include the $6 Vibrapod, which are very helpful under CD players or speakers, again not a megabuck item. It would also include Audio Research tube damper rings which are also quite inexpensive but can improve the performance of almost any tube component for about $20(I forgot,"most" all tube designs are worthy of scorn anyway), again I will asume that you have tried these products and found them of no benifit? I know of people who squander lots of cash upgrading components that say "cables make no difference" only to find out that their new(fill in the blank) sounds just as bad as the old one did,i.e. too bright, or too harsh,or whatever the complaint was. This is because the brightness,harshness, or hardness, or whatever came from their cables and not the component. The system does not have to cost a fortune to be able to hear very real improvments from items like these.
all 1 the whole quantity, substance, duration, amount,or degree of;2 collectivley, the whole amount or number of, as of individuals or particulars............... Opinions are like,hummmmmmmm? what was that?........everyone has one.
