Short answer: the Dynaudio Emit 30. It ranks #50 of 73 floorstanding speakers by sound quality, rated 3.9/5, at $1,274.25. The Sony SS-CS3 ranks #68, rated 2.8/5, at $450, $824.25 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Dynaudio Emit 30 does well: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. Watch for: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven (sometimes soft, sometimes forward) depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result.
What the Sony SS-CS3 does well: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. The tradeoff: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments.
Worth knowing: the Sony SS-CS3 has been discontinued and is hard to find new at this point.
Buy the Dynaudio Emit 30. It is rated higher for sound quality, and the $824.25 you would save on the Sony SS-CS3 does not close the gap.

The Two Speakers In Full
Dynaudio Emit 30: $1,274.25 per pair Amazon eBay
Pros: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. The two woofers hand off at staggered crossover points (around 1kHz and 3.5kHz) rather than sharing one, which avoids the acoustic lobing a shared crossover point would cause between the tweeter and the lower woofer, and adds a few dB of sensitivity in the process. Genuinely deep bass for a speaker around this price: measured F3 near 44Hz and extends audibly down to about 40Hz in-room without much difficulty. Harmonic distortion measures clean and low at both 86dB and 96dB SPL/1m. Good CTA-2034 sound power and uniform directivity mean the speaker takes EQ correction well if a listener wants to dial in its one tonal weak point. Dynamic range and compression performance are strong overall, with only a minor, high-Q compression artifact tied to a cone-edge resonance that’s unlikely to be audible. Wide, consistent horizontal dispersion around ±70° with just a small ~10° narrowing between 1-3kHz, and a reasonably forgiving ±20° vertical window centered on the tweeter axis. Measured bass extension of 44Hz (-3dB).
Cons: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven (sometimes soft, sometimes forward) depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result. A cone-edge surround resonance shows up around 1-1.3kHz in burst-decay measurements (a trait the reviewer has also seen on other Dynaudio models) and lines up with elevated multitone distortion across roughly 600Hz-1.5kHz. An enclosure resonance appears around 350Hz in the impedance curve. Placed too close to a rear wall, the dual ports make the bass noticeably boomy: pulling the speaker out is needed to keep the low end from overloading the room. Fully resolving the top-end inconsistency needs a modest EQ correction (roughly +2dB with a Q of about 1, centered 3-6kHz), so out-of-the-box tonal accuracy in that band isn’t quite class-leading despite otherwise strong measured performance.

Sony SS-CS3: $450.00 per pair Discontinued eBay
Pros: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. Harmonic distortion remains reasonably low at moderate listening levels (86dB SPL) when high-pass filtered above 80-100Hz with a dedicated subwoofer. Front-ported design allows relatively close placement to front boundaries without excessive port occlusion. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 88.6dB.
Cons: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments. Irregular frequency response peaks and dips make automated receiver room correction difficult to equalize effectively. Poor low-frequency extension (F3 of 72Hz, F10 of 39Hz) for a floorstander, combined with rapid distortion escalation below 80Hz at higher SPLs (96dB+). Supertweeter driver adds crossover complexity without providing audible high-frequency benefit within the human hearing spectrum. Discontinued.
