I only keep speakers and source equipment that I find exceptional compared to what is available today. Some components just seem to find a special place in my mind and aural memory. IF, I SOLD, I know that I would regret it sooner or later. If I needed the money to pursue an upgrade that would be a tough decision and I am sure it would require some serious internal debate. Newer is not always better, then again, we only live so long and we must balance the curiosity of owning something different and perhaps letting others enjoy our past favorites. 😉
