Short answer: the GR-Research NX-Studio. It ranks #4 of 222 bookshelf speakers by sound quality, rated 4.8/5, at $3,630. The ELAC Vela BS 403.2 ranks #33, rated 4.4/5, at $3,299, $331 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the ELAC Vela BS 403.2: A stylish two way bookshelf speaker with a folded ribbon tweeter, an aluminum sandwich woofer, and a choice of high gloss finishes. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
The GR-Research NX-Studio is the better-sounding pick. A DIY kit bookshelf speaker with a ribbon tweeter for wide open, detailed sound, superb imaging, and tight, fast sealed bass. The catch: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.
Buy the GR-Research NX-Studio. It is rated higher for sound quality, and the $331 saving on the ELAC Vela BS 403.2 is not enough to make up the difference.
About the ratings: the ELAC Vela BS 403.2’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.2 to 4.6, so this verdict could change once it is measured.
