Disciplined audiophile, that's an interesting idea. I won't wait if the sound is markedly unpleasant. Maybe a few days at most. If it's really nice it's easy to let it go for a few months - if my love affair with the new sound lasts that long. Or, so long as some new idea doesn't intrigue me enough to want to try it. I've messed up a lot of what I thought were great sounding setups only because I got an idea in my head and was curious to try it.
For whatever reason I have a thirst not just to achieve good sound, but to better understand what it is that makes me think it's good. Just last night and this morning I decided to have a new look at my midrange horn, which has been difficult to interpret since it's measured response varies so much with measuring distance and angle. It's a weird beast and I don't know what's right. I tried a method I learned of yesterday called "beamforming" for measuring. You basically add the measurements together that are taken at various distances. This has the effect of suppressing the effect of early reflections, so the direct response of the horn can be more clearly seen, and adjusted as needed with crossover settings and equalization. The end result seemed to give good overall room response, but boy did that do something weird. The bass seems hard to hear, vocals seems very clear and natural but much louder than the bass, even though the bass measures as loud as ever. Before I did this experiment the system was sounding great.
So no, I'm not disciplined. I didn't even bother to save the settings I had earlier when it sounded great because I was too eager to try new things.
