Short answer: the Neumi BS5. It ranks #38 of 179 bookshelf speakers by sound quality (rated 3.8/5) at $139.99 and is still sold new; the Jamo S 803 ranks #176 (rated 1.4/5) and is discontinued, so it is only an option used.
The Neumi BS5 is the better-sounding option. Budget bookshelf speakers with accurate, punchy sound that work with any ordinary receiver, an exceptional value. Watch for: Erin measured F3 at 64Hz, so kick-drum punch should not be mistaken for deep-bass extension.
What the Jamo S 803 does well: A cheap, compact discontinued bookshelf speaker with a front port and punchy bass, suited to desktops or surround duty. Watch for: A textbook V-shaped response rather than accurate reproduction.
Buy the Neumi BS5. It is rated higher for sound quality, and the Jamo S 803 is discontinued, so it is only available used.
