Speakers for leading edge, transients, speed and big sound

Von Schweikert speakers with a easy placement due to their adjustable active bass.  The more expensive models have more adjustments.  The smaller, less expensive models play big, superior dispersion and adding a pair of 10" shockwave subs should power/balance the sound in moderately large size rooms.  Otherwise, Rockports are balanced sounding with outstanding sonic characteristics.  If you want precision over musicality, there are many modern speakers from Vivid, Magico, Wilson, B&W, Borressen, et.al.  which will fill the bill, the bigger units with bigger, defined and fast bass.

Jay's Audio on Youtube announced this weekend that Von Schweikert speakers are comparable to Sonus Faber and Magico if they had a baby, high resolution, huge dynamics, huge soundstage and musicality.  Even the new VR 30 speaker with a pair of 10" VS subs can fill a large room or balance a small room with the adjustable (not in DSP/digital domain) subs permitting easy speaker placement and fundamentals to shake your room.
