SQ and aesthetics.
I have an open area where my 2-channels is located. For various reasons I’ve really tried to integrate the system into living space so that it doesn’t bring too much attention to itself.
For me, it’s more than just the components, but the way in which the system contributes and interacts with the living space both acoustically and aesthetically during the day and especially in the evening.
Service/support and value (used market) should probably be much higher if I were to be completely transparent with myself, though. And enjoyment per knotscott. Enjoyment would definitely take the cake if it were one of your options. Otherwise why bother?
