I'm using these with a 7350 APM (which is required to get the bass extension if you're doing anything below 100Hz), and the quality of sound is flawless. Precise, sharp, revealing, clear. The GLM system and room correction just simply works and provides fantastic control over the monitors, without making standalone use impractical. Lack of AES input is the only problem, fixed by moving to the 8330s. Standalone these lack enough power for high levels of LF but with the 7350 taking everything from 85Hz down there's really no problem at normal listening levels.
