Short answer: both are discontinued, and they are rated the same for sound quality (#23 and #17 of 163 floorstanding speakers). Either one is only an option used, so choose on condition and price. If you want one new, the KEF Reference 5 Meta replaces the KEF Reference 5 and is rated 4.8/5 at $49,999.96.
What the KEF Reference 5 does well: A tall three-way tower with KEF’s Uni-Q array, a 1” aluminium tweeter inside a 5” aluminium midrange, between four 6.5” aluminium woofers, plus interchangeable port tubes to tune the bass to the room. The catch: KEF’s data is not reliable below 200Hz, so it has no preference score; the rating is estimated from it and the Reference 5 Meta that replaced it.
The case for the KEF Reference 203: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. The catch: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums): condition, driver matching, and component aging vary by unit, so audition before buying if at all possible.
Buy the KEF Reference 5 or the KEF Reference 203, whichever you find used in better condition; both are discontinued. For a new speaker, buy the KEF Reference 5 Meta, which replaces the KEF Reference 5.
About the ratings: the KEF Reference 5’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.3 to 4.9, so this verdict could change once it is measured.

The Two Speakers In Full
KEF Reference 5: $19,000 per pair Discontinued Estimated eBay
Newer model: the KEF Reference 5 Meta, ranked higher, estimated 4.8/5.
Matching center: the KEF Reference 4c (rated 4.1/5).
Pros: A tall three-way tower with KEF’s Uni-Q array, a 1” aluminium tweeter inside a 5” aluminium midrange, between four 6.5” aluminium woofers, plus interchangeable port tubes to tune the bass to the room. KEF’s own measurements show a very smooth listening window and sound power. Sensitivity is 90dB.
Cons: KEF’s data is not reliable below 200Hz, so it has no preference score; the rating is estimated from it and the Reference 5 Meta that replaced it. It weighs 60kg each. Discontinued.

KEF Reference 203: $5,000 per pair Discontinued eBay
Newer model: the KEF Reference 3 Meta, ranked lower, rated 4.6/5.
Pros: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. Distortion is excellent: under 1% harmonic above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good”: a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.
Cons: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums): condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening.
