Well v3 (both alphas) definitely sound different. There is significantly more bass. I don't know if I would call the changes better as I haven't adjusted my eq/amps to compensate yet. I was actually going to ask if that added bass was going to stay before I readjust everything.
Agree completely, Rob -- I haven't even tried v3.00a5 yet, but *I* noticed a huge difference in my In-Car audio from 2.00 to 3.00a3. (In case it really is a bug, Once I upgraded, all my EQ's displayed flat. however, it sounded like my EQ was still actually loaded.)
Me.
