Short answer: the Sony SS-CS3 for better sound quality, the Infinity Reference 253 for the lower price. The Sony SS-CS3 ranks #47 of 56 floorstanding speakers at $450. The Infinity Reference 253 ranks #48 at $400, $50 cheaper.
What the Sony SS-CS3 gets right: 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 catch: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments.
What the Infinity Reference 253 offers: Horizontal beamwidth of about ±60 degrees is fairly smooth and well controlled. Watch for: CEA2034 spinorama and predicted in-room response both show elevated treble above 4kHz (“too hot”), a dip around 2kHz, and bass shelved down relative to the midrange.
Buy the Sony SS-CS3 if sound quality matters more than the price. Buy the Infinity Reference 253 if the price matters more than sound quality.
If sound quality matters at all to you, skip both of these and look higher up the 56 floorstanding speakers instead.

Sony SS-CS3: $450.00 Discontinued
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.
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.

Infinity Reference 253: $400 used, Discontinued
Pros: Horizontal beamwidth of about ±60 degrees is fairly smooth and well controlled. Really amazing value for the performance.
Cons: CEA2034 spinorama and predicted in-room response both show elevated treble above 4kHz (“too hot”), a dip around 2kHz, and bass shelved down relative to the midrange. Vertical directivity requires staying at or below the tweeter axis for accurate tonal balance. Distortion at 96dB SPL/1m is broadly elevated above the reviewer’s audibility threshold across much of the midrange. Minimum impedance dips to 4.2 ohms. Discontinued.
