Short answer: the ELAC Debut 3.0 DF63. It ranks #73 of 188 floorstanding speakers by sound quality (rated 4.2/5) at $1,298 and is still sold new; the Sony SS-CS3 ranks #177 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SS-CS3’s replacement, the Sony SS-CS3 M2, is rated 3.0/5.
The ELAC Debut 3.0 DF63 is the more accurate choice. Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. Its measured preference score, a predictor of how neutral it sounds, is 5.83 against 4.11 for the Sony SS-CS3. The tradeoff: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals.
The case for the Sony SS-CS3: 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.
Buy the ELAC Debut 3.0 DF63. It is rated higher for sound quality, and the Sony SS-CS3 is discontinued, so it is only available used.

ELAC Debut 3.0 DF63: $1,298 per pair Amazon eBay
Same family: the ELAC Debut 3.0 DB53 (smaller bookshelf, estimated 3.9/5), the ELAC Debut 3.0 DB63 (larger bookshelf, rated 4.2/5), the ELAC Debut 3.0 DF53 (smaller floorstanding, ranked lower, estimated 4.2/5), the ELAC Debut 3.0 DC53 (smaller center, estimated 3.4/5) and the ELAC Debut 3.0 DC63 (larger center, estimated 3.5/5).
Pros: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. The dedicated midrange driver keeps distortion low even at higher output, avoiding the intermodulation grain typical of two-way bookshelf designs. The waveguide keeps high-frequency directivity well controlled, and overall horizontal directivity is good up to about 2kHz. Harmonic distortion looks good at both 86dB and 96dB, and multitone distortion stays below the reviewer’s 3% threshold. A shallow bass rolloff (F3 71Hz, F10 29Hz) lets it extend fairly low without a hard cutoff. Preferred by the reviewer over the similarly-priced Polk Reserve R500 (too much high-frequency narrowing, less neutral) and considered ahead of the Polk Audio Reserve R700 as well. Measured bass extension of 71Hz (-3dB), with a measured sensitivity of 86.6dB.
Cons: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals. A mild peak around 10kHz makes shakers and similar high-frequency percussion jump too far forward in the mix; needed about 2dB of EQ to tame in testing. A dip in the 1-3kHz range gives the speaker a warm, slightly veiled character: the reviewer suspects the tweeter crossover point (around 2-3kHz) is set a bit high and could be lowered to fill this in. Directivity shows a noticeable handoff mismatch around 2.5kHz where the midrange driver hands off to the tweeter, though it’s minor at the -6dB point. Vertical directivity is narrower than horizontal, so listeners need to stay close to the tweeter axis. Low EPDR (about 1.5 ohms minimum) means a Class AB amplifier should be well-ventilated. Best positioned pointed directly at the listener and closer to the front wall: toeing it out into the room causes too much high-frequency rolloff.

Sony SS-CS3: $450 per pair Discontinued eBay
Newer model: the Sony SS-CS3 M2, ranked higher, estimated 3/5.
Same family: the Sony SS-CS5 (bookshelf, rated 3.5/5).
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.
