There are a lot of speakers that can compete. Not sure if they will be fundamentally better but will be different. MBL and Avantgarde have radicaly different designs at the high end that could easily compete.
In terms of raw engineering, I would be shocked if anyone spends more on speaker development than Wilson Benesch courtesy of British Government subsidies. I haven’t tested vs Wilson’s at this level, but I would be very optimistic that certainly the Eminence could go toe-to-toe but I would love to hear the Omnium or Resolution up against them. I think it would be closer than you think.
