Back in the days before Audiogon was sold to new profit oriented owners, it was also a credible forum which attracted many knowledgable posters. Among them was JaFox, an advanced audiophile and music lover who was a very articulate writer. He owned Sound Lab A1 speakers and Cat amps starting in about 2006, previously being a Maggie and ARC fan. His many posts over the years, which I enjoyed and benefitted from can be found here:

His thoughts on Sound Labs, come later. A lot to read, but worth the time!
