My experience with breakin was just what you are seeing at the moment. it will likely go through several stages before it settles in. A little weak in the bass at first, at some points dark and closed in, then sounding a little tipped up in the HF. Once you get about 100 hrs on it, it will stablize.
with respect to VTA - My MD was installed with my tt by Lloyd Walker. Neutral VTA was set as a baseline using 180g LPs, then reset again for 200g and then again for 140g LPs, so that each LP thickness can be quickly dialed in prior to play.
VTF was set at right around the middle of the manufacturer's guide line: 2.2-2.3g?
My turntable is so stable with respect to settings, it has been pretty much "set it and forget it" except for VTA adjustments where needed.
currently have the cart loaded at 100 ohms.
