So I just installed a new stylus as the last one was reaching the end of its usable life, and have found myself constantly fiddling with the VTF - set several years ago and left to do its thing - forever trying to find the sweet spot between a wide open sound stage with a soaring top end, and the point where the music becomes a little more cohesive and focused with less top end, and fewer dynamics. In reality this is a minor adjustment. I'm going from 1.77 - 1.85 (and several increments between). To my ears, it makes a significant change to the sound, and - I'm finding - alters with regards to sweet spot per record. Maybe the new stylus just needs to break in a little more. Think I'm at the 20 hour mark. Hoping to find my back to 'set and forget', but I'd be lying if I said that it didn't bug me right now. So, and with this in mind, who finds themselves fiddling with VTF? Do you set and forget? Constantly tweak? Find that the sweet spot changes depending upon the record? If so, how would you describe the differences in sound between light and heavy VTF? I imagine it's system dependent to a certain extent?
