In the reference level of preamps, the KX-R is somewhat a bargain at its original MSRP of $18,500. And that’s because it easily kept pace with some preamps costing three or even four times as much. When paired with the matching MX-R monoblock amps (also for sale in a separate listing), the combo is incredibly transparent, airy sounding, clean and uncolored. If you want a preamp that is uncolored and plainly neutral, the KX-R is an excellent choice. Music flows through from source to speakers undiluted with every nuances on the CD conveyed through. If you plan on getting either the KX-R or MX-R or both, make sure if you top notch source unit and speakers to go along. Or else you would be just short changing yourself from what the Ayre pieces are capable off. Like the MX-R, the KX-R is literally “carved” out from a block of aluminum. You can feel its solidity all around by just knocking it with your knuckles.
Cosmetically, the KX-R is in very good shape. Some minor scuff marks here and there but nothing major. Preamp will be securely packed for safe shipping.
