Better choice for a starter 2ch system between JBL 590 refurbs ($760) and Klipsch RP-280FA ($600)? Powered by a Denon AVR
The Klipsch RP-280FA have upward firing Atmos speakers in them; you'd be better off with the RP-280F unless you plan to extend the 2ch system into an Atmos home theater at a later date.
I own a 7.2 channel Klipsch reference system with RF-82 II upfront and I'd choose the JBL 590. The Klipsch are great for home theater and have better choices for matching center channels and surrounds. But for stereo only go with the JBL.
