85 db or more efficient speaker recommendations

Starting with my system and preferences to narrow things a bit:

Nottingham Spacedeck with upgraded Van den Hul silver cable, Boston Audio graphite mat, Origin Live gravity weight, SME309 arm with a bit of extra mass and resonance damping, Hana Umami red cartridge, Hagerman Trumpet MC with Telefunken smooth plate ax7’s and Valvo 3 mica e83cc, extra damping, crystal cable, Cayin A 300B amp with Takayuki 300 B tubes and various nos tubes, anti cables and zero autoformers, Omega AlNiCo junior speakers, Omega subs, various other tweaks, bases, isolation and room treatments.  I listen mostly to classical and older rock and folk (think CSNY, Moody Blues, Yes, Steely Dan and Joni Mitchell).

My main priorities are large holographic sound stage with excellent imaging, nice musical coherence (not a sterile or clinical analytic sound).  Less important is the last little bit of inner set or perfect FR.  Good dynamics too.

seeking recommendations that might do better than the Omegas for speakers.  Price limit $6,000 per pair new.  The Omegas are really very good for the price, just wondering if I can do better.

What a hobby/disease!

thanks for any input.
