MF A3 integrated upgrade

John is one of the gems of the hifi world! His knowledge of electronics, upgrades and the general industry is just staggering; he’s willing to share it too, always keen for a good chat about your system and upgrade potential, a wealth of expertise and great advice. Not only has he transformed my A3 into a genuinely high end amplifier, with the performance of an amp costing several times the purchase price, he’s also offered hugely effective advice and tips on other areas of my system including cabling and tweaks.
Basically that great phenomenon during listening whereby the system just disappears and jaws drop in disbelief at the realism of a great recording, now occurs far more regularly. Without a doubt the best upgrade I’ve made so far. When can JS upgrade the rest of my system!!? Thanks very much John.
