It’s been a couple of weeks since you’ve changed to the 14b....what improvements have you noticed?
Hey Bud1451, Yeah, it's not so obvious the differences unless I a/b I think (which I cannot do). But my overall impression is that the bass is very well handled at high volumes like no sweat. I wasn't expecting a huge jump in performance vs 4b3, but more giving my speakers all the headroom they would need to eliminate any doubt of detail loss in the lower frequencies (since they are rated 650W program and 86dB efficiency). I made the decision mostly on that basis and would recommend you consider what speakers you are driving before going to the 14B3 and whether it could be worth it for you.
Sorry I couldn't give a more detailed impression and certainly don't want to speak out my A$$.
