This is all very interesting and we all have many valid points. My only point in identifying other speakers I've had is as a basis for those which I'm comparing the sound of the SP Tech's to. To my ears, the SP Techs have been the best out of the gate and I'm not hearing anything that would lead me to believe I won't enjoy them for the long term. One thing I do know for certain - there are very few of us right now that have any basis to speak about them with any direct knowledge. I personally consider myself lucky in that regard and will spend a lot of time enjoying them. I hope you all can have the same privilege, regardless of what vehicle you choose to ride.
