Not yet released is Ayre’s 175Wpc VX-5 amplifier (price TBD, in the $8000 "neighborhood"), which uses the same circuit as in the AX-5, but with a larger power supply and higher voltage rails. The VX-5 was demmed with Vivid G2Giya speakers and the K-5xe^MP preamplifier that John Atkinson reviewed in June 2011.
