Simple to Use and So Affordable! Try a Few Sets for Yourself!  Meant to be used in sets of three, the Ayre Myrtle Blocks go between the chassis of the component and the supporting shelf. These replacement feet should be slightly taller than most stock feet. You'll be captivated with the improved musicality these wood blocks provide! At this price, what do you have to lose? Try this Stereophile Recommended product out for yourself!

“The [Ayre] Myrtle Blocks happen to be designed and made by Cardas, in accordance with the ‘Golden-Section Ratio’ (each block measures 0.618” by 1” by 1.61”). Unlike other things that come and go in less than a season’s time, I’m still using the Ayre Myrtle Blocks; they remain my favorite and most heartily recommended cheap tweak!”
