How long do you keep a component?


What is the average length of time between your audio purchases or upgrades? Which components do you trade out most often? Amplifiers, Pre amp’s, speakers, front end, cables, or tweaks? For me it seems to be Amps, speakers, cables and tweaks not necessarily in that order.
minutia
Two weeks to nine years. I tried more cables than anything 'cause it's the easiest. Next in line are amps, no wait, make that CD players, then amps, then preamps then speakers.
That's easy. For me, it's speakers. I've had 4 different pairs in less than a year. I surprise myself if I hang on to any speakers more than four monts. I'm kind of new to high end. Only been involved about seriously for about 3 years. Next in line is definitely preamps. I've had three of those in the past year. I just like to trade to hear what is out there. I haven't traded amps in a while though...
The shortest time was a very expensive D to A converter. Lasted only a few days. Next worse was one of the newest ultra high end preamps, it lasted only three weeks before passing it on and returning to the bliss of my Aesthetix.

The longest running component ever is Soundlab speakers. Discovered them about 1986, decided to buy in 1989 and have only momentarily considered other brands during that twelve year period.
I tend to hang on to things for a while--I had my Duntech Princesses 11 years, and my Sforzandos for the last 4, and I've had my JA 80s for 11, my JP80, my Basis and Graham and my Day-Sequerra for 9 and my Forsell/Audio Logic combo for 8. I do change cartridges more frequently, although I think I've reached Nirvana with the Koetsu RSP, and cabling changes are more frequent as well. I do note that although I've kept the above components a long time, I have continually upgraded them --for example, after 8 years I got the Debut platter/bearing/vacuum upgrade for my Basis Ovation; I've upgraded the Graham from 1.5T to 2.2, upgraded the Forsell to Mk IV after 5 years and the Audio Logic to 2400 at the same time, and have consistently fiddled with the tubes in my pre and amps (although with the stash of Gold Lions and a recent score on early 60s Tele 802 and 803S tubes, I think I'm set for life there). I guess that's how I fall for the upgrade bug!
