Its always better to use a better stereo amp than to use lesser monoblox
Just to clarify a little on that.
"It’s always better for sound quality to use a stereo amp if you have enough wattage, than to use "bridged" monoblocks of the same amp."
As all that’s gained by "bridging" is extra wattage, every other parameter that’s important for "sound quality" in an amp’s make up specs take a hit.
