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 MoFi SourcePoint 8 ranks #17, rated 4.5/5, at $2,594, $1,036 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the MoFi SourcePoint 8 does well: A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. The catch: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
Why pick the GR-Research NX-Studio: 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 saving $1,036 with the MoFi SourcePoint 8 does not make up for the sound-quality gap.
