Short answer: the Revel M126Be. It ranks #28 of 84 bookshelf speakers by sound quality at $4400; the Yamaha NS-800A ranks #42 and costs $4800, so there is not much of a tradeoff to weigh.
What the Revel M126Be offers: Two-way design pairing a 6.5” midwoofer with a 1” beryllium dome tweeter, the smaller sibling to the reviewer’s favorite Revel F226Be. Watch for: At $4,400/pair, the reviewer doesn’t consider it a strong value - an improvement over Revel’s less expensive M106 and Performa3 models, but not proportional to the price jump.
What the Yamaha NS-800A offers: Exceptionally well-built cabinet with no internal resonance issues at all - confirmed clean in both burst decay and impedance measurements. Watch for: A wide, roughly 2kHz-10kHz scoop in the upper-midrange/lower-treble gives it a laidback, soft, low-attack character - notably worse than the reviewer’s Audio First Fidelia reference in an A/B comparison.
Buy the Revel M126Be. It ranks higher for sound quality than the Yamaha NS-800A and costs less, so there is no real case for the other one.

The Two Speakers In Full
Revel M126Be: $4400 Crutchfield
Pros: Two-way design pairing a 6.5” midwoofer with a 1” beryllium dome tweeter, the smaller sibling to the reviewer’s favorite Revel F226Be. Wide, immersive stereo imaging - hard-panned sounds in test tracks localized 2-3 feet outside the physical speaker positions without losing pinpoint precision. Horizontal radiation of about 60-70°, landing right in the reviewer’s preferred range for an enveloping yet still well-focused soundstage. Extended bass-shelf tuning (similar in concept to the KEF R3 Meta) combines with in-room gain for a more linear low end rather than a boomy hump. Diffraction dips visible on-axis around 3kHz and 7kHz largely disappear in the estimated in-room response, since they fill in as you move off-axis. Distortion stays within 3% down to about 100Hz at both 86dB and 96dB output - strong performance for a 6.5” bookshelf woofer. Can be driven by a standard AVR thanks to a manageable 4.9-ohm minimum impedance.
Cons: At $4,400/pair, the reviewer doesn’t consider it a strong value - an improvement over Revel’s less expensive M106 and Performa3 models, but not proportional to the price jump. Bass tops out around 50Hz in-room; a subwoofer is still needed for real low-end extension. Vertical placement is fairly critical - there’s a notable hole in the response around the 1.7kHz crossover if you sit above the tweeter axis. Toeing the speaker out to a full 30° introduces a roughly 1dB discontinuity in the midrange along with high-frequency rolloff; the reviewer recommends staying close to on-axis or within about 10°. An unexplained jump in distortion appears right at the 1.7kHz crossover point under compression testing, which may be linked to an occasional “glaring” quality the reviewer noticed in the 2-3kHz region at very high volumes (92-93dB from 2 meters). A mild 2-3kHz forwardness occasionally stood out on some tracks, correctable with about 1dB of EQ, though the reviewer considers it minor.

Yamaha NS-800A: $4800 The Music Room
Pros: Exceptionally well-built cabinet with no internal resonance issues at all - confirmed clean in both burst decay and impedance measurements. Good, wide directivity (~75 degrees horizontal) that stays consistent enough to EQ successfully. Distortion is low, staying under 3% at 96dB, and dynamic range holds up well until right near its 102dB limit. A shallower, higher-frequency bass rolloff profile (F3 68Hz, F10 35Hz) means it can be placed closer to the wall (about a foot) without turning boomy, actually gaining bass presence rather than losing it.
Cons: A wide, roughly 2kHz-10kHz scoop in the upper-midrange/lower-treble gives it a laidback, soft, low-attack character - notably worse than the reviewer’s Audio First Fidelia reference in an A/B comparison. On top of that, treble breaks up badly above 10kHz, swinging up as much as 8dB - a significant, named flaw. Sounds inconsistently voiced as a result (bright on some material like cymbals and shakers, dull/laidback on vocals and instrument attack) until corrected with real parametric EQ (the reviewer needed a +2dB boost around 4.5kHz at Q0.5 plus taming the treble spike to bring it to life) combined with near-wall placement and 30-degree toe-out. Without that combination, it’s a tough sale for a $4,800 bookshelf speaker.
