Comparing one’s own system to speakers heard at audio shows, stores, or even other people’s listening rooms is questionable at best. To know if some product might improve the SQ of one’s own system requires auditioning it at home for at least a week’s worth of critical listening.
That said, I own Von Schweikert, PSB and Magneplanar speakers (all full-range floor standers) and half a dozen lesser monitors; I’ve auditioned Martin Logan "The Quest" and three different iterations of B&Ws, each for weeks. Finally, friends in our local audio club have uncompromising rigs of various kinds: stacked Quads, Harbeths, Dynaudios, KEFs, MBL 101 Radialstrahlers in a specially constructed listening "room" built in consultation with an acoustician that is larger and more opulent than most people’s entire homes.... And yet, I have not found anything I prefer to my Scientific Fidelity "Teslas," built in the early 1990s. A bad review in Stereophile pretty much killed the company. Recently, Bill Legall at Millersound restored the drivers for me. They cost a mere $1000 in 1992 (I got them used), and they even look great. My second system has settled on the Magneplanar 1.6 QRs installed in an acoustically treated room just right for them, but the Teslas in my living room remain my favorites.
