I am going to move to a smaller apartment with a listening area of 13.5'L x 10.5'W x 8.5' (ceiling). As such I'm leaning towards the M5 Sapphire. But I read somewhere that the M5 Sapphire requires at least 3 feet from the front wall otherwise the bass levels will be reduced. For this reason if I cannot pull out the M5 more than 2 feet, will M3 with its double bass drivers be an appropriate choice in terms of bass levels. My music choice mostly smooth jazz and vocals. My present setup consists of Innuos Zen Mk3 & Jay's Audio CDT2MK2 Transport feeding Vinnie Rossi L2i-SE with L2 DAC and out to Harbeth SHL5+ 40th Anniversary speakers. Any M5 or M3 owners out there I wish to hear your opinions and suggestions.
