Ayre Acoustics KX-R stereo premp. Stereophile recommended. $18,500 MSRP

Selling for $7,995.00

High end preamp



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. We have listened to this side by side with their current KX-R Twenty and the difference is really down to splitting hairs. But one thing is for sure, the KX-R Twenty costs many thousands more!

Cosmetically, the KX-R is in very good shape. Some minor scuff marks here and there but nothing major. The first two letters – “AY” on the front branding has peeled off but you can buy replacement stickers from Ayre. We have the original remote, manual and box. Preamp will be securely packed for safe shipping.
