I am glad you know about Kal and I appreciate you posting the link on his review of the SP3. I noted the article was dated May 2012; well by July 2012, I was at an audio store called "The HiFi House" in Jenkinstown, Pennsylvania ...
I was auditioning systems at Hifi House 2013-2014. Before I could decide on what I wanted, they got bank liquidated in 2014

I bought some stuff from their other store's liquidation sale.
I heard awesome stuff there, most notably the Sonus Faber and Totem Tribe III.
The SP3 was/is out of my price range. I settled for the Krell Foundation, which I'm quite happy with. I can't see upgrading from it because (1) everything with comparable sonics is so freaking expensive and (2) I only want 7.x - no need for Atmos, ever.
