Short answer: the Sony SS-CS3. It ranks #47 of 56 floorstanding speakers by sound quality at $450; the Magnepan LRS+ ranks #50 and costs $1300, so there is not much of a tradeoff to weigh.
On the Sony SS-CS3 side: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. Set against that: 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 Magnepan LRS+ offers: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). Watch for: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output - a robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it.
Buy the Sony SS-CS3. It ranks higher for sound quality than the Magnepan LRS+ and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip both of these and look higher up the 56 floorstanding speakers instead.

The Two Speakers In Full
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.

Magnepan LRS+: $1300 Magnepan
Pros: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). Delivers a uniquely dramatic and enveloping soundstage with genuinely three-dimensional depth effects that work across all music genres, not just classical or orchestral material as commonly assumed. Extremely tight, locked-in center-phantom imaging when set up correctly. Open-baffle design avoids the “boxy” enclosure coloration of conventional cabinet speakers. Multitone distortion is remarkably consistent from low to high frequency, a characteristic the reviewer hasn’t observed in conventional cone-and-dome speakers. Compression at high output stays modest (about 0.5-1dB) through the midrange and treble, giving roughly 20-26dB of usable dynamic range in that region. At its price, a strong contender for a dedicated secondary listening room, even if not a main-system replacement.
Cons: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output - a robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it. Bass rolls off very quickly (F3 74Hz, F10 67Hz, described as falling off “like a rock”), making a subwoofer an absolute requirement for any low-end content. A roughly 3dB dip in the mid-bass (100-300Hz) region thins out vocal body and fullness compared to a conventional bookshelf speaker. A resonance/bump around 400Hz adds a mild boxy quality, though it responds well to about 2dB of EQ correction. Extraordinarily fussy about exact positioning - both seating height (must align with the acoustic reference point between the panel’s lower tie-down points) and horizontal aiming are unusually critical; moving just a couple of inches can cause treble content above roughly 500-600Hz to nearly vanish. Distinct off-axis cancellation zones exist directly to the sides of the panel, where very little sound is audible at all. Fails badly under extreme dynamic-transient testing in the bass, and the reviewer blew fuses pushing the speaker during testing - not built for high-volume or highly dynamic playback. A genuinely different category from conventional hi-fi speakers, requiring more setup patience and experimentation than a typical monopole design.
