Another speaker I heard for the first time is the Sanders Sound System Model 10e. I have heard other models of Sanders speakers many times but the newest model with an aluminum bass driver and revised transmission line now incorporates a digital crossover, room correction, digital signal processing, and a real time analyser using a DBX 360 unit. I believe the room correction is only used below 500Hz. I was astounded by the amount of additional clarity and focus over the already exceptional performance of previous models. The package retails for $17,000 including one Sanders Sound Systems Magtech amplifier, one of my personal reference amplifiers because it is extremely versatile and works very well with everything I have tried it on.
