I recently istalled 5 dedicated lines; 3 20amp and 2 30amp lines. One line for the digital front end; one for the turntable and phono preamp; one for tape deck. One 30amp line for each of my Krell 650MC's.
A dedicated line for each amp will improve dynamics and costs virtually nothing extra to install. If they have to run two lines, why not throw in a couple extra for good measure. Be certain to install hospital grade or audiophile grade sockets in the wall. They have a tighter connection. I used Romex, 10 gauge wire from the wall to my box,but some other audiophiles have mentioned a better stranded wire for audio. I can't remember the name.
when the job is complete, allow at least two days of having your equipment on for the new lines to break-in. My were harsh sounding at first, then glorious when burned in.
Best tweek there is in my mind. Much better than swapping for new equipment.
