op we heard the steinway sstems at several audio shows not impressed and this is a verry expensivw system
we heard the aurion audio apollo system at capitol audio fest this is a full range line array of proprietary amts drivers with a pair of diapole subwoofers
the use the trinov processor for a preamp dac crossover and for room correction 60k for the speakers and they bow away speakers for 200k and they are 105db efficient so a tiny tube amplifier is all you need
so this system uses the same elements that you like in the steinway system
