Sir the sound of 5050, 4250 and 4150 is better then 3250, they also have a better equalizer, display and PRE out to connect AMP.
New 4250SD will cost you nearly 11,000 after a bargain.
Better buy the 5050, 4150 or 3250 used from any PW member in good condition and invest on some good front speakers, preferably components.
