One reason that people keep their Rockport speakers is they are so heavy and difficult to ship,,,who wants to do that....easier just to say you love them and live with them....much like a marriage...Not Rockport but my reason not upgrading yet. LOL! Lucky still happy with my speaker.
Heard neighbor’s Altair II with VTL Siegfried II and Ypsilon sources. Full body, resolving, powerful, organic ... He upgraded to Arrakis and now Altair is available if interested.
Heard Alexx at event with Bob McGrath. Exceptional speaker. Little dark with MSB amp. Too bad didn’t use Momentum.
Bottom line can’t go wrong with any at price range. All great just matter of taste.
