Genesis 501 speaker sound

I read reviews and literature concerning these speakers. However, I have never heard them. It seems that I can' t find any dealer whereby I can audition them prior to purchasing. I am updating from the Infinity IRS-Sigmas. I know that the 501's are very tuneable, but that's is all I know about them, I definitely do not want to spend BIG money for no improvement. Or worse, going backwards. I listen primarily to classical music with occasional jazz and old standards by Sinatra, Peggy Lee, some big band,etc. I would appreciate any help regarding the 501's. I use the Aragon Palladium II monoblocks with the Pass Labs X-1 preamp. Thankks
