goodhifi, could there have been something else awry, i've had the gcph in my house and its much quieter than my little CA 640p and that is in the mid 80db snr.
heard the anatek with the cheapy Kuzma and prologue amps into the SF elipses this weekend at the show.
And it sounded exceptional, spatious, clear, fine detail and dynamics and very liquid.
i'd be guesing it's a discreet class A unit, defo no opamp taint to the sound and no hint of valveness.
its on my to buy list, knocking off the GCPH purely because its british.
Some sort of interference pickup?
case earthed?
