BHK 250 Amp with 94dB efficient horn speakers

I’d be going balanced throughout, connections between amps and to Dac.

Was the BHK or spend a bit more and get a Mac.
Need to think about my speakers though, and suitability for such a high wattage amp.

BHK (and careful use of volume) may be the sweet spot.
Synergy with the Pre has to be a given?
