Using a really rigid arm with a countersunk balance weight improved things on the TT2 as well as the LP12 for me. Without losing the midrange details this cleans up the bass a lot. It did not bring forward the midrange details on the LP12 though- That’s why we kept the TT2 and I sold the LP12 …
present state of the TT2:
16mm birchply fixed through with two stainless screws, rewired RB250, Michell VTA and fingernut, steel stub, Expressimo heavyweight, Stanton 681eee with Pickering 625e stylus, Tonearm cable by back25beat10.
Heed Orbit2 and Trichord Dino Mk1:
Result: detailed mids, fast and controlled bass, detailed treble (as far up as I stil can hear with 47 :-)); dynamics are absolutely on par to my dynamics refernce, a Yamaha CDP-930 from 1992.
YMMV, but this is it for me at the moment, need nothing "more"
