I was curious as to what degrees other forum members tweak/obsess/nitpick over their system? This is not an all encompassing list but I consider a tweak (right or wrong) to be calibrating your TT, moving components or seating around, room treatments, power conditioning or outlets, vibration control, racks, etc. I don’t think a tweak is new speakers, amps, cartridge, source, or any other large box purchase. Those are larger than tweaks and there are other threads to share those purchases in. My most recent tweak was to try some IsoAcoustics Orea feet under my TT. I originally had the stock feet and then went to Vibrapods w/cones and was pleasantly surprised at the added clarity in voices and air around instruments. Of course I wanted more so I replaced the Vibrapods with a bamboo butcher block and Diversitech mp2-e anti vibration pads (the black and blue ones). This was a clear regression and the best way to describe it was that the music lost some of its boogie. The IsoAcoustic Orea feet brought back the boogie and surpassed my involvement I had with the Vibrapod/cones setup. Lyrics sound clearer than ever and there’s more air around everyone, it’s awesome!
