Short answer: the Genelec 8340A. It ranks #33 of 119 powered bookshelf speakers by sound quality (rated 4.4/5) at $3,790 and is still sold new; the Genelec 8040B ranks #57 (rated 4.3/5) and is discontinued, so it is only an option used.
The case for the Genelec 8340A: A compact aluminum studio monitor with clean, extended response, automatic room calibration, and analog and digital inputs. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
What the Genelec 8040B does well: A compact professional studio monitor with balanced XLR input and analog room controls for easy placement. Watch for: It lacks GLM calibration and consumer streaming inputs.
Buy the Genelec 8340A. It is rated higher for sound quality, and the Genelec 8040B is discontinued, so it is only available used.
Worth knowing: the Genelec 8340A has not been measured yet. Its rating is estimated from related models, with a likely range of 4.2 to 4.6, so treat this verdict as provisional.
