Many thanks, John. I was shocked initially by the difference in performance before and after. So much so, I decided to take some time to evaluate the upgrade fully. I remain stunned. My hifi has always meant a lot to me. Now it means much more. I heartily recommend these upgrades. Bass is easily extended without bloom. The essential midrange brings necessary and naturalistic clarity to recordings. Female vocals are particularly well rendered with every nuance of the vocal line, tone and breath, revealed. The power on tap is also surprising, meaning my speakers can now deliver their potential without being overworked.
