Standmount speakers. I have $5000.

I'm shopping standmount speakers. I have $5000.  New or pre-owned is fine.

And:

Micromega M100 integrated pre/amp/dac
Syzygy SLF870 sub x2 (12" drivers, 1200w ea, 20-200Hz, room correction)
Dynaudio Stand 4

room = ~5000 cu. ft, 20'x 18' with 13'-17' vaulted ceiling

The new standmounts will replace Nola Boxers v1 ($1500 new in 2013)

I'm lazy about travel to audition anything but might for local options (esp. to vet pre-owned). I'd probly deal with in-home trial.

As semi-arbitrary starting point I'm looking at Salk SS 7M's ($4995 new). Any others I simply must consider?

Thanks!
