How often do you swap out equipment in general

I'll make impulse purchases just to try out the latest thing; most recently a pair of Usher S-520s, a Bel Canto dac2 and an Oppo 980. I listened to the Ushers for a while just for a change and sold them at very little loss. The Oppo and dac2 will stay until I need to sell them for some other interesting piece. This is part of the hobby for me but most of the mainstays in my system are a couple years old now. I have no desire to change them out as they are very musically satisfying to me.

If I can keep everything static for 6 months, I am doing good. I just can't help thinking there is something out there that is better than what I have. Cables, power conditioner, etc. I have had my speakers for about 5 years now. That is the record for me. It's a sickness, I know. But I'm not complaining, it could be worse.

Well to qualify my reply I am broke...dead broke!

But all the same I have at times day dreamed over this speaker or that amp and that cart with this table but I find myself at a point where I am really happy over all and dont waste time dreaming of unobtainable gear. The largest reason I think I have changed is now I have my own room so everything performs at a level I'd never heard before. I do still read all mags and peak at ad's and manuals online and attend shows but more of curiousity than a dream plan.

I've had my amp and CDP for approx. 1 year... speakers and preamp are relatively new additions, going on 3 months. I'm low on $$$ right now, so I'll make an occassional small purchase ($300 or so) on tube rolling till I get another large infusion of cash in the form of my annual bonus or tax refund in 2009. If money were not a constraint, I'd probably be making significant component changes every 4 to 6 months or so. I typically like to move up vs. just making lateral moves in terms of quality and price. I'm satisfied that my system has come a very long way in the last 3 or 4 years that I've been serious about this hobby.

the only surviving member of my system thus far
has been the adcom gda600DAC, which i've had
since 96 , i think. wow! that's a 6th grader man!!!!
