Got sold to someone else today! Decision was made for me. would have Been a no brained if I didn’t already have 2 decent subs but I did so I can enjoy what I have and think bigger :) So what are ya gonna do? I decided not to buy the Klipsch To go with my SVs pb2000 as generally I’ve decider to upgrade only to the extent that it’s a major upgrade. Got me thinking. From where I am now, what would be a dramatic upgrade? And if the walls already rattle, what differences would I see with say the dual 18 psa or monolith just to set an extreme example?
