Short answer: the GR-Research NX-Studio for the higher ranking, the ELAC Debut 2.0 B6.2 for the lower price. The GR-Research NX-Studio ranks #1 of 47 bookshelf speakers at $3630. The ELAC Debut 2.0 B6.2 ranks #32 at $479, $3151 cheaper.
On the ELAC Debut 2.0 B6.2 side: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity. The tradeoff: A good size resonant peak around 700hz, directivity error around 3.3khz.
The case for the GR-Research NX-Studio: Ultra clean burst decay/waterfall plot. The tradeoff: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.
Buy the ELAC Debut 2.0 B6.2 if the price matters more than the ranking. Buy the GR-Research NX-Studio if the ranking matters more than the price.

ELAC Debut 2.0 B6.2: $479.00 Crutchfield Amazon
Pros: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity. Its larger-than-typical woofer lets it play very loud with minimal distortion, and minimum impedance stays a comfortable 5 ohms.
Cons: A good size resonant peak around 700hz, directivity error around 3.3khz. Predicted in-room response shows a lack of energy between 1-2kHz and a bit too much above that, which the reviewer thought would sound bright. Distortion at 96dB SPL/1m shows two harmonic peaks the reviewer says “should not be there,” one from woofer breakup around 400Hz and another around 7-8kHz from the tweeter. Cumulative spectral decay (waterfall) shows the same 700Hz resonance lingering. The reviewer needed EQ (taming the 700Hz peak, filling in the 1-2kHz dip, and trimming the highs) to get it sounding its best.

GR-Research NX-Studio: $3630 Gr-research
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.
