Short answer: the JBL L52 Classic, though neither ranks well in its class. It ranks #131 of 179 bookshelf speakers by sound quality (rated 2.6/5) at $999 and is still sold new; the Jamo C 93 II ranks #174 (rated 1.5/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 179 bookshelf speakers, and the Philharmonic Ceramic Mini, ranked #2 at $900, is a better place to start if sound quality matters.
The JBL L52 Classic is the more accurate pick. A retro bookshelf speaker with a walnut veneer cabinet, colorful foam grille and punchy upper bass. Its measured preference score, a predictor of how neutral it sounds, is 4.54 against 3.35 for the Jamo C 93 II. Watch for: Measured compression and distortion behavior from about 1-5 kHz was inconsistent (“wonky”) across output levels, and didn’t clean up even at lower volume; adding a subwoofer high-pass didn’t fix the high-frequency distortion either.
The case for the Jamo C 93 II: A compact discontinued bookshelf speaker with a 6 inch woofer and an attractive cabinet for the price. The catch: Extremely non-linear tonal balance: Erin measured treble averaging roughly 5dB above the midrange, with local swings from near the midrange level to +6dB by about 12kHz.

Measured Differences
- Bass depth: the JBL L52 Classic reaches 45 Hz (10 dB down) against 53.2 Hz for the Jamo C 93 II, about half an octave deeper. You hear more of the lowest bass notes and kick drums.
- Tonal accuracy above the bass: with a subwoofer taking the low end, the JBL L52 Classic scores 7.0 against 6.0 for the Jamo C 93 II on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
