In 1979 I put together my first assault putting together a high end system by taking out my first loan for $5,000 (that is $18,871 in today’s dollars) for. Threshold s500 amp, my system was all solid state. Over the years of continuously investing and learning, and trading up… one by one each of my components were swapped out for tube equipment. Now, by far the best system I have ever had… all of my components are tubed. (Click on my user ID to see my systems).
