Great news on the SFs, Steve. If I was in the market for a 6-figure speaker, that would be my first audition.
Have heard great things about Hansen, just pretty price prohibitive compared to competitors such as Wilson/Magico made in the states. Resale is terrible on them.
I have heard the Hansen Prince and compared to Rockport Merak Sheritan II and YG Acoustics Ref...Hansen was a very solid performer. But relative to the other 2, in that room and in that system...no magic. Ypsilon and Electrocompaniet amplification and Boulder 2020 source.
My preference for sound was Rockport, my admiration for technical advancement, detail retrieval was clearly YGA and the Hansen was just a good solid overall performer but did not impart its own magic...neither super-live sounding music, nor extreme dynamics, just solid but not great in any way. Perhaps this is why resale is difficult?
To make a product successful these days, differentiation is very, very important. Even if you are going to be a solid all around performer, you need to be different...Devialet is a great example...very, very good in many areas, but not top, top, tops for a 5-figure component in any one performance area...except one...its extreme design, size, user-friendly installation and slim figure.
Just as a personal preference to show my own bias, I'd rather have SF Guarneris plus a kick-ass sub or 2, and struggle to make them blend but get superb magic in certain areas, than the Hansen Princes.
