Short answer: the MoFi SourcePoint 888. It ranks #8 of 228 floorstanding speakers by sound quality (rated 4.7/5) at $5,495 and is still sold new; the KEF Reference 203 ranks #17 (rated 4.6/5) and is discontinued, so it is only an option used. The KEF Reference 203’s replacement, the KEF Reference 3 Meta, is rated 4.6/5 at $15,999.98.
The MoFi SourcePoint 888 is the deeper-bass option. Excellent floorstanding speakers for the money, with near full range bass and effortless dynamics. Its bass reaches about 34Hz before falling 3dB, against 51Hz for the KEF Reference 203. Watch for: A significant investment, best ordered from a dealer with a good return policy.
Why pick the KEF Reference 203: A classic four way floorstander with neutral, accurate sound and low distortion, now discontinued but worth buying used. The tradeoff: 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 MoFi SourcePoint 888. It is rated higher for sound quality and still sold new, while the KEF Reference 203 is discontinued.
