EXPIRED - FOR SALE: Ayre KX-5 Preamplifier
A preamp may be the most important piece in any system and this unit is certainly one of the best available at any price. Following in the legendary footsteps of the KX-R preamplifier, the Ayre KX-5 lives up to the challenge with dynamics powered by their Diamond output stage and a finesse achieved by eliminating the traditional attenuating volume control with their 46 position Variable Gain Transimpedance (VGT) amplification circuit. Mint condition. Email me if you have any questions. Please include your phone number if you are a serious buyer.
