I am probably one of the worst when it comes to swapping out components. In the past 2.5 years I have had 4 different speakers, 4 different preamps, 3 different amps, and 4 different cdps. My system has remained stable for the past 2-3 months which is a record for me. I usually start thinking about changing things out right about now. I am actually kind of depressed because I know my system is stable now. For the foreseeable future, I will be looking into cables and other tweaks which should somewhat satisfy my upgrade itch though it will never give me the same thrill as getting an new component.
