For sale my year old Primaluna Prologue One. This amplifier has given me more pleasure than any amp I have ever owned. I am upgrading to the Dialogue range. It is as new condition and looks and sounds fabulous. Build quality belies it's price. Like a tank!! I am selling with the supplied valves which have around 50 hour use PLUS 4 x Cryo'ed Harma EL34's, 4 x Shuguang NOS 6CA7's and 2 x Harma Diamond ECC83's. RRP is £1195 - selling for £650 plus p&p or pick up/meet half way.
