I have been meaning to write this review for the past three years as john upgraded my full suite of Musical Fidelity KW gear. The result even three ears later still blows people away. Subsequent to to the upgrades I moved to Kenya and managed to damage the Power Amp due to crap power out here but John not only helped me diagnose the issue but also got the parts to me so I can have a local electrician fix it :).
sterling bloke who does exceptional work. Wish I lived near enough to get the new upgrades done on my Kit.
