Short answer: the JBL Studio 530 for better sound quality, the Sony SS-CS5 M2 for the lower price. The JBL Studio 530 ranks #23 of 56 bookshelf speakers at $399. The Sony SS-CS5 M2 ranks #25 at $278, $121 cheaper.
What the JBL Studio 530 gets right: CEA2034 spinorama shows a fairly flat on-axis response. The catch: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz.
On the Sony SS-CS5 M2 side: 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. Set against that: Mild sibilance in the 3-5kHz range stands out on S and T sounds in vocals.
Buy the JBL Studio 530 if sound quality matters more than the price. Buy the Sony SS-CS5 M2 if the price matters more than sound quality.

JBL Studio 530: $399 Discontinued
Pros: CEA2034 spinorama shows a fairly flat on-axis response. Predicted in-room response is very smooth aside from the high-frequency roll-off.
Cons: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz. Response rolls off in the high frequencies and the tuning is a bit bass-shy overall. Cumulative spectral decay (waterfall) shows the same 1kHz-region resonances lingering in time. Discontinued.

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.
