Thanks for the resolute recommendations for Ayre! @efoo, The QX-5 is a streaming amp.
Richard Vandersteen also suggested Ayre for amplification, but the more affordable units don’t have optimal amounts of power for the Vandersteen speakers, so I got the Belles Soloist. RV recommends high quality components with 0 feedback.
@efoo, NAD discontinued the M50.2 a couple years ago. They moved on to the M10 (now the v2 version) M33 and M66. None has quite the functionality I seek—a fully integrated ripper, storage, server, streamer.
