Short answer: the GR-Research NX-Studio on measured sound quality, the GR-Research NX-Bravo on price. The GR-Research NX-Studio ranks #4 of 214 bookshelf speakers, rated 4.8/5, at $3,630. The GR-Research NX-Bravo ranks #26, rated 4.4/5, at $1,540, $2,090 cheaper.
The GR-Research NX-Studio is the better-sounding choice. Ultra clean burst decay/waterfall plot. Watch for: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.
The case for the GR-Research NX-Bravo: Vertical dispersion is unusually wide for a two-way bookshelf: tonal matching holds from about 50° above the tweeter axis down to 20° below it, well beyond the roughly ±10-20° typical of most two-ways. The catch: Pointed straight on-axis there’s a deliberate ~5dB high-frequency bump meant to compensate for narrowing dispersion off-axis; it needs about 15° of toe-out (aimed to cross behind the listener) to sound balanced, which won’t suit every room layout.
Buy the GR-Research NX-Studio when sound quality outweighs the price for you, and the GR-Research NX-Bravo when the price outweighs sound quality instead.

The Two Speakers In Full
GR-Research NX-Studio: $3630 per pair GR Research eBay
Same family: the GR-Research NX-Bravo (smaller bookshelf, ranked lower, rated 4.4/5) and the GR-Research NX-Treme (floorstanding, rated 4.8/5).
Pros: Ultra clean burst decay/waterfall plot. Amazingly open sounding due to the semi open baffle Neo3 ribbon tweeter, will image better than any other bookshelf speaker. Neo3 ribbon tweeter is one of the best ribbons around for detail. Bass will be very tight and fast due to the sealed enclosure, but may possibly need a sub.
Cons: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.

GR-Research NX-Bravo: $1540 per pair kit with finished cabinets (assembly required) GR Research eBay
Same family: the GR-Research NX-Studio (larger bookshelf, ranked higher, rated 4.8/5) and the GR-Research NX-Treme (floorstanding, rated 4.8/5).
Pros: Vertical dispersion is unusually wide for a two-way bookshelf: tonal matching holds from about 50° above the tweeter axis down to 20° below it, well beyond the roughly ±10-20° typical of most two-ways. Horizontal dispersion is also wide at about ±70° through the midrange, widening further when toed out, so sidewall acoustic treatment isn’t really necessary. Burst decay is extremely clean with essentially no ringing: the reviewer compared it favorably to a $13,000/pair speaker that showed significant ringing at 120Hz and 500Hz. A deliberate dip around 7kHz reduces sibilance while the 1-4kHz upper-midrange stays neutral, so the sound doesn’t come across as laid-back or recessed. Easy to drive electrically, with a 5-ohm minimum impedance and 2.5-ohm minimum EPDR. Available from $700 as a kit up to about $2,500 fully finished, with the option of the designer’s flush-mount tube/banana-plug terminals for a cleaner look. Measured bass extension of 77Hz (-3dB), with a measured sensitivity of 84.8dB.
Cons: Pointed straight on-axis there’s a deliberate ~5dB high-frequency bump meant to compensate for narrowing dispersion off-axis; it needs about 15° of toe-out (aimed to cross behind the listener) to sound balanced, which won’t suit every room layout. Higher-than-normal high-frequency distortion becomes audible in sine-sweep testing at higher output, and multitone distortion crosses the reviewer’s 3% threshold around 96dB, making roughly 88dB the safer output ceiling. SPL-limited by the manufacturer’s own admission: not intended for loud, full-range playback and best paired with a subwoofer, as with most two-way bookshelf designs. F3 of 77Hz and F10 of 45Hz mean bass only reaches about 50-60Hz in-room. A minor enclosure or port resonance shows up in the frequency response (though not in burst decay), likely a non-issue but visible in measurements. Adding a subwoofer reduces midrange distortion but doesn’t address the elevated high-frequency distortion.
