Sorry if this has been asked before but a couple of searches haven't turned up anything close.
So , I'm running a 50WRMSx4 amp with a S/N ration of >90db and THD of<.1% and am fairly content.
Would I hear a noteable difference if I swapped it out for somthing that delivers 70Wx4RMS, S/N >100db , THD<.5%?
I'm running decient ($150, 92DB, 90WRMS) components at (usaully) 1/2 volume with mostly accoustic, folk and classic rock. I hate to drop $200-$300 on an upgrade if the difference is in the weeds but would do it if it would be "$ well spent".
