Proprius

For what it's worth, my pair of Proprius is piggy back to a early 1990's BW 620 much tweaked 8inch cone with a bass radiator inside a 30 litre Volume box and very balanced in musicality, and loud enough to fill a 3.5 metre by 5.5 metre lounge sitting room. Acoustic music recordings of late 70's to 90's mellow and sweet tone and is there to stay until I can no longer feel the sheer music to enrich my soul .....But Electronic Pre-amp on my DAC output 2.7 V is the weak link. Yes, libran interconnect from Proprius to the 30 litre Speaker saves for expense Speaker cable and the beauty of two mono amps to create the sound stage is super value.
