Short answer: the Sony SS-CS5 M2. It ranks #25 of 56 bookshelf speakers by sound quality at $278; the JBL Stage 2 250B ranks #30 and costs $349.95, so there is not much of a tradeoff to weigh.
What the Sony SS-CS5 M2 offers: Added internal bracing (corners, sides, front baffle) plus an updated crossover meaningfully reduce the resonance issues that plagued the original SS-CS5, giving a smoother, more neutral character overall. Watch for: Mild sibilance in the 3-5kHz range stands out on S and T sounds in vocals.
On the JBL Stage 2 250B side: Consistent, EQ-able dips in the frequency response mean the tonal issues are at least correctable if you’re willing to use equalization. Set against that: The reviewer was “even less enthusiastic” about this one than its disappointing floorstanding sibling.
Buy the Sony SS-CS5 M2. It ranks higher for sound quality than the JBL Stage 2 250B and costs less, so there is no real case for the other one.

Sony SS-CS5 M2: $278.00 Amazon
Pros: Added internal bracing (corners, sides, front baffle) plus an updated crossover meaningfully reduce the resonance issues that plagued the original SS-CS5, giving a smoother, more neutral character overall. A modest mid-range dip (about 1-2dB) is present but tolerable, and the reviewer would rather have this dip than a peak in that region. Slightly deeper bass than the previous version, measuring about 2dB more output around 60Hz. Distortion drops noticeably when crossed to a subwoofer around 80-120Hz, meaningfully improving midrange clarity and detail versus running full-range. Easy to drive on a standard AVR - no need for a dedicated high-power amplifier. More modern, understated waveguide look compared to the previous version’s glossy trim.
Cons: Mild sibilance in the 3-5kHz range stands out on S and T sounds in vocals. Some forwardness in the midrange noticeable on certain vocal recordings. Soundstage and sense of envelopment are comparatively flat and two-dimensional, especially next to reference-quality speakers with strong 3D imaging. Marketed as a “three-way” design mainly due to an added super-tweeter that the reviewer considers largely superfluous - it engages only at very high frequencies and adds complexity without a clearly audible benefit, when that cost might have been better spent on the main crossover. Output-limited: realistic ceiling is around the mid-90s dB SPL at a few meters, with comfortable listening closer to 75-85dB at 3-4 meters before distortion and compression become audible. Bass noticeably compresses/shelves below about 120Hz as volume increases, softening kick-drum impact at higher output. Smaller drivers and a lighter motor structure than rivals like the Polk XT20, which the reviewer generally prefers for its better directivity and higher SPL capability. Still needs a subwoofer for any real bass extension.

JBL Stage 2 250B: $349.95 Amazon
Pros: Consistent, EQ-able dips in the frequency response mean the tonal issues are at least correctable if you’re willing to use equalization. Horizontal dispersion is reasonably wide and controlled (~50-60 degrees). The tweeter itself holds up fine under compression testing - it’s the midwoofer that gives out first.
Cons: The reviewer was “even less enthusiastic” about this one than its disappointing floorstanding sibling. A confusing, hard-to-place tonal signature - a lower-midrange dip creates a recessed, lacking-attack character that’s then partly offset by a rebound around 2-4kHz, so it reads as recessed and forward at different times depending on the material. Treble falls off sharply above 6-7kHz, same issue as the larger 280F. Multitone distortion at 96dB is genuinely poor - well over 3%, reportedly around 10% at some frequencies. Limited bass extension (F3 64Hz, F10 50Hz) means a subwoofer is basically required if used as main speakers. Compression sets in early on the bass/midwoofer at higher output. The reviewer explicitly recommends the similarly-priced Polk Reserve R200/R100 instead for anyone who wants a more linear, EQ-free sound.
