More a list for warning people about buying "new" gear, here's a list of relatively well-known audio companies that appear to be slowly winding down, even though they appear to have a continued presence on the web. I understand that high end audio companies generally release product at a slower rate than mass-market companies, but if you haven't updated your website in years, or haven't had a new product in four years... Theta Digital - Released a new amp in 2005, and an updated Cassablanca in 2017. No updates since then, and their latest Cassablanca has never had a software update. Adcom - Looks like they are still actively selling new hardware, but no new product development in several years Most Harman brands, except for Mark Levinson, JBL and Lexicon. Infinity hasn't released a new home speaker in years, looks like they are focusing on car and marine audio. Harman Kardon seems to be focusing on sound bars and bluetooth speakers. Most of their other home audio products are several years old. Wadia - No new product in four years. Krell - New products are sporadic, their top-of-the-line HT processor is six years old, their most recent product an HT amplifier released last year, or the year before. Any others?
