KLIPSCH! It depends, depends on your room, your amp, type of music you listen to, and the sound you are seeking, etc. I’ve never heard the Revel, but I have a pair of Klipsch Forte IIIs and Focal Aria 926 in my main rig. Based on what I’ve read about the Revel, my guess is they’d have a similar sound signature of my Focals based on their similar builds.
i run both with a 20 wpc 300b 845 tube amp in a wide room with 12 foot ceiling streaming Qobuz through an IRIS DDC and Pontus II DAC. Pretty resolving system. I bounce back and forth between the two speakers depending on mood, music, and even time of day. Listen to jazz, folk, Americana, country, pop, rock, some classical. I love the way both set of speakers sound, different but both excellent.
I always return to the Klipsch as “reference” for what I like, HUGH soundstage, deep, wide, tall, very dynamic, superb vocal midrange presentation. Not forgiving of poor recordings however. The Focals are warmer, yes warmer with more mid and lower bass, smaller more narrow soundstage, more “intimate” sound presentation, more forgiving of poor recordings.
But when I want big sound, lifelike presentation, even at low volume, it’s always the Klipsch! Just my preference.
