vp, i assume that you are using the 300Bs for their finesse. so is it more of a qualitative thing? i use low powered class a amps on them in my living room without issue. i have a 20 watt class a ss power amp and a 22 watt class a tube amp and both are wonderful for me. any louder and my wife would kill me with a corn broom.
