best matching full range speakers for sx880 pioneer (60W rms per channel)

I have the SX-680 version (45 wpc) and have had it paired with both my JBL L40 and ADS L520 speakers for many many years. I slightly prefer the ADS sound for its less fatiguing tone but the JBLs sound more dynamic. These receivers deliver surprisingly good balanced sound. You just need to decide what kind of sound you're looking for in a speaker. There's an ADS L810 listed right now for $275 and could sound real nice with your SX-880. Great speakers with particularly solid bass.

As a new owner of a pair of 30 year old 2Cis, I concur with Johnny R's assessment. I'm now tempted to hook up my SX-680 to these speakers just to see how they sound.....
