Hey John, how ya been, long time no see...
Yes I had the 2 sigs, started on my journey with the Rotel and then had the Cary SLI 80.
Your probably right the Cary didnt have enough oomph...
I remember wishing I could get the dynamic sound you had in your room, (believe it was with the Quicksilver mono tubes amongst others I remember).
Anyway not trying to knock the Vandies, but I could never get them to float an image like I could with other speakers, and the resolution could have been better (in my system anyway)
You are right though. I havent heard the latest iterations from Mr. Vandersteen lately.
I hope all is well with you and your family and I wish you a Happy and healthy New Year!
Take care
Mike
