I am a retired engineer who has been intermittently involved in audio since I was a teenager. Built Dynaco amp and tuner from kits and built several sets of speakers from plans back in the 1970s. Looking to replace the towers that I built back then with something better and have been searching many forums gathering information. May also build a sub based on what I decide on for the L&R mains. Main interest is in music (classic rock), but my receiver is connected to TV and DVD player for movies and concert videos.
