The quest for better sound. This site can really help to suck you into it for sure, and have seen some people go to extraordinary lengths to achieve it.
But as Donberry eluded to-it's a never ending one. It can be tiring. Both to ones self and wallet. Tempering it usually seems to work for me. Of late, I have used upgrading my 2 pairs of AMT3's as the tempering agent.-as It takes allot of time with my schedule, and it's relatively inexpensive, and educational to boot.
In the mean time, I get to listen to a few older set's of speakers in the rotation, which gives me a better feel for the direction I'm headed.
Luckily, I pretty much have my electronics set, and use the speakers to get the sound/voicing I'm looking for. Each person goes a different path, demands, etc -but this one keeps me from switching out too many components and losing site, or slipping back, of the progress I've made. More or less my "break".
