Hi guys, I am setting up a new system and need suggestion about which speakers to buy. Since I am into classical music, some suggest me to buy Philharmonic Affordable Accuracy(AA) bookshelf/floor. I can also get a pair of Infinity P363 tower one-year-like-new for just 100. I heard the rated impedance of P363 is 4 ohm. But I will purchase a middle end(?) receiver like Yamaha RX-V1700 or Denon AVR-3805, and hopefully it can drive the P363. So which ones should I buy? Infinity P363 or AA bookshelf/floor? Thank you in advance!
