Short answer: the Genelec 8351B. It ranks #4 of 119 powered bookshelf speakers by sound quality, rated 4.8/5, at $9,900. The Genelec 8350A ranks #25, rated 4.5/5, at $5,550, $4,350 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Genelec 8350A does well: An 8 inch studio monitor with bass deep enough for most music, plenty of output, and automatic room calibration. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the Genelec 8351B: Coaxial three-way studio monitors with highly accurate sound, deep bass, low distortion, and automatic room calibration for precise listening. Watch for: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material.
Buy the Genelec 8351B. It is rated higher for sound quality, and the $4,350 saving on the Genelec 8350A is not enough to make up the difference.
Worth knowing: the Genelec 8350A has not been measured yet. Its rating is estimated from related models, with a likely range of 4.3 to 4.7, so treat this verdict as provisional.
