I still need to do some more testing on it, but I'd say it's somewhere in-between the Q701 and Anniversary in quantity. Extensions pretty good, so it might be a case of the Anniversary having more mid bass but the T90 catching up a little near the sub-bass. Quality however is better than both with the T90. Better texture and variety (not one-notey) and quicker speed. Not Planar levels, but good for a dynamic.
