Short answer: the Wharfedale Diamond 220 for better sound quality, the Sony SS-CS5 M2 for the lower price. The Wharfedale Diamond 220 ranks #19 of 56 bookshelf speakers at $350. The Sony SS-CS5 M2 ranks #25 at $278, $72 cheaper.
The case for the Wharfedale Diamond 220: Amir found the on-axis response smooth once the grille is removed, calling grille removal “a huge improvement” since the stock grille caused unusually strong comb filtering around 5kHz. The tradeoff: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use.
What the Sony SS-CS5 M2 gets right: 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. The catch: Mild sibilance in the 3-5kHz range stands out on S and T sounds in vocals.
Buy the Wharfedale Diamond 220 if sound quality matters more than the price. Buy the Sony SS-CS5 M2 if the price matters more than sound quality.

Wharfedale Diamond 220: $350 Amazon
Pros: Amir found the on-axis response smooth once the grille is removed, calling grille removal “a huge improvement” since the stock grille caused unusually strong comb filtering around 5kHz. Good horizontal dispersion from the waveguide-loaded tweeter and controlled distortion. After some EQ (a room mode filter and treble shelf), the reviewer called it “a truly hifi speaker” where “every audiophile track…sounded very good,” and said he was “happy to recommend” it for the budget class.
Cons: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use. Some port rattling was noted at high volumes, traced to vibration rather than the woofer itself. Best performance requires removing the grille and applying the reviewer’s EQ filters.

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.
