My impression of many of the contributors to Audiogon is best described by the word "addiction". I have been monitoring this forum for over three years now - and sense a prevailing "dissatisfaction" amongst the members here. This is particularly evident when comparing Audiogon to forums like Audiokarma,, Vinyl Engine, and HiFi Engine - where maintenance, repair, and upgrade of beloved components are fully addressed.
I must admit that I have been involved with this hobby for over 65 years - and thus have a special interest in "vintage" components and recordings. Please note that the greatest advances in high fidelity recording and component audio engineering occurred in the 1950's and 1960"s. Early stereo recordings made by RCA and Mercury still "hold their own" compared to the prevailing "digital" techniques used today!
Also note that monophonic LP's comprise some of the most treasured items in my extensive vinyl collection. The music itself is of primary importance; as some of the contributors to this thread have emphasized. Let us not be turned away from the music in a desperate search for the latest $5000 power cable that will not produce an iota of true satisfaction.when listening to a reference recording!
