Used Ayre amp market pricing
thanks for following up 
recommendations of phono preamps < $3000 range

Class A/B Home THeater Receivers
Pretty sure all the Denon/Marantz, Anthem, Yamaha (Aventage, at least), and Onkyo are still Class A/B.  Let me know if you find out otherwise, but I thought it was mostly Pioneer who was heading Class D in HT receivers.
