My Dad was an EE w/ multiple patents (like my grandfather) & into hi fi from the 50"s onward. He was pretty smart & knew a lot about audio as well as electronics in general. He had a few different Dynaco power amps he built & heavily modified to power his quite large Bozak speakers he also built from parts he got from Rudy Bozak. I know there were two 50 watt mono amps & also a stereo 70 at one time too but don't remember if he biamped or not. The amps were on a shelf he built in the basement connected to the main floor floor joists just below the speakers in the living room w/ his preamp , turntable & tape deck in a cabinet in the living room itself.
Anyway, he used no power cords at all for the amp but simply ran "homeruns" from the electric panel to the amps & hard wired them directly into the amps! He rarely did anything w/o a well thought reason so I'm wondering why he opted for this?
Wouldn't you think that the best power cord is no power cord? Obviously, there are practical reasons why this wouldn't always work but for folks like many here who are totally into the ultimate best sound they can get out of their systems, I surprised this is not mentioned?
