Thieliste, not sure you want to hear this, however, each time I pull up Thiel 3.7 or 7.2 on YouTube, nearly every video there was krell on these speaker’s, I mind you, they sounded damn good to me, I understand opinions are just that, an opinion1990’s videos. It’s 2017!
I’m a Krell fan, owned 3 and last FPB600 ... great in its time Current SS is in a different world ... no comparison!
The best I heard 7.2 was at Stereo Shop on Mass Ave in Arlington, MA driven by a full stack of McIntosh.
If by any chance the Ypsilons can handle both of these speakers i would rather go the Ypsilon route.I would definitely demo before purchase.
