Ayre Acoustics K-5xeMP Preamplifier
“The Ayre K-5x is a killer preamp…” – Shane Buettner, The Audio Perfectionist
“I was impressed by Ayre Acoustics’ K-5xeMP. For what is these days a relatively affordable price, it offers much of the sound quality you can get from the megabucks solid-state preamps. While the original K-5xe was a solid Class B recommendation in Stereophile’s “Recommended Components,” this Maximum Performance version deserves a full Class A rating.” – John Atkinson (Stereophile), 2011
