The S&K are wonderful but a rather different beast to the ATC 100 which you alluded to. A mere lamb versus a lion perhaps. Given your new larger room size and existing tastes I am not sure S&K would be at all suitable. (S&K nano's max peak output is a mere 104 db SPL and therefore a big step down from your existing SCM 20's which play continuously at close to 108 db SPL in your old small room)
Anyway you may have to wade through everyone's favorite speaker under 6 K listed here without respect to your "taste" or preferences.
I'd suggest to check out used bigger PMC speakers also...kind of an industrial look (with the Volts) but certainly a more modern appearance than ATC.
