YBA Integre DT integrated amplifier. Used regularly when new, but has been largely unused in recent years. Lives in a climate controlled environment (always has). A perennial Stereophile Class "A" rated integrated amplifier. With the right ancillary components you'll hear a gorgeous (expansive) soundstage and dynamics. It's simply a pleasure to listen to with all types of music for as long as you'd care to listen. Currently used with B&W Nautilus 805 speakers and a CalAudioLabs CD Player or Fanfare receiver and the results are stunning (as if you're in the studio during recording). Non smoker and adult owned and utilized exclusively. Hear all the music, rendered transparently. This unit has always performed flawlessly and does so today as well. If you've never auditioned this amplifier, your conclusion upon hearing it will almost certainly be the same as that of the professional critics after their auditions i.e., they are converts to it's honest, colorless rendering of the recording and the audiophile quality (build/design/sonics). Cumulative U.S. inflation rate would reflect a sales price of over $3000. for this amplifier if purchased new today. If you already know about this integrated, no explanation is warranted. Once you hear it, you will very likely understand immediately the praise showered willingly upon it over the years. Consider these 2 typical reviews: (http://hometheaterreview.com/yba-integre-integrated-amp-reviewed/?page=2), (http://www.stereophile.com/integratedamps/636/#xAHAIx3VqD0zoyVc.97). Although these reviews are dated much earlier than when I acquired my new Integrate DT, I find them absolutely relevant/accurate. Thanks for looking!
