Short answer: both are discontinued, so this only matters if you are buying used. Used, the Selah Audio Purezza is the better pick: it ranks #31 of 222 bookshelf speakers by sound quality (rated 4.4/5), against #39 (rated 4.3/5) for the ELAC VELA BS 403. If you want one new, the ELAC Vela BS 403.2 replaces the ELAC VELA BS 403 and is rated 4.4/5 at $3,299.
The Selah Audio Purezza is the more accurate option. A premium bookshelf speaker with a Purifi woofer and ribbon tweeter, very low midrange distortion, and smooth, broad horizontal sound. Its measured preference score, a predictor of how neutral it sounds, is 5.61 against 3.94 for the ELAC VELA BS 403. The catch: The ribbon’s tall aperture creates deliberately narrow vertical radiation (roughly 20-30 degrees around 7kHz), so stand height and listening elevation are critical.
The ELAC VELA BS 403 is the deeper-bass pick. A stylish bookshelf speaker with a folded ribbon tweeter, neutral voicing, a spacious soundstage, and good dynamics for its size. Its bass reaches about 59Hz before falling 3dB, against 86Hz for the Selah Audio Purezza. The catch: Deliberate dip-and-peak voicing in the crossover region around 2 kHz reduces attack and clarity in the mids and highs: intentional per ELAC’s design, but not to Erin’s personal preference.
Buy the Selah Audio Purezza only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the ELAC Vela BS 403.2, which replaces the ELAC VELA BS 403.
