Again..tenured music lover. As a hobby, it's natural to want to move on and "get closer" over time. For me, the home run is the music, and no nostalgia to what gets me there. I don't marry the gear. I'm fully awakened when a tweak or gear improvement "freshens" your entire collection, yet again! Nor am I saddened when things seem to get a little tired and boring. It simply means it's time to get more creative somewhere in your system. There is ALWAYS something one can do, even if it simply means turning your electrical panel mains and circuits on-off a couple times every 6 months. Loudspeaker placement and DSP adjustments also can freshen everything without cost...sometimes I prefer more center-fill, sometime more depth of field or stage-width. It's all an amazing illusion, after all, play with it! More peace, Pin.
