Actually, I have three long-term "rotating" hobbies: (1)audio; (2)motorcycles (particularly Harleys); and (3) Photography.
After spending several days/months/years (and $$$) obsessing about upgrading the audio system, to the point of reaching the sensory overload stage where you scream "no more tweaks!" I simply go into the garage and figure out what modifications my motorcycles might like/need. Then I spend the next few days/months/years (and more $$$) working on motorcycles. Once I reach the saturation point with motorcycles, I move on to upgrading camera equipment (even more $$$) and taking more photos.
Then repeat.
It's like taking mini-vacations from one's obsessions..... by obsessing about a different obsession.
