I have been wanting to replace my crown macrotechs with powersoft for some time but its not as if I can demo them. I am somewhat skeptical since they only find it necessary to published wattage ratings at EIAJ test standard, 1 kHz, 1% THD. No 20/20 ratings ?- whats the deal with this? Does anyone have those ratings? / specifically for Powersoft M50Q & M28Q. Or can anyone here vouch for these amps? Is the power at least 3/4 that wattage at 20/20?
