Short answer: the Polk R200. It ranks #178 of 222 bookshelf speakers by sound quality, rated 3.2/5, at $799. The HSU Research CCB-8 ranks #213, rated 2.3/5, at $699, $100 cheaper, which does not close the gap in sound quality.
The Polk R200 is the more accurate option. A Polk bookshelf speaker with a 6.5 inch woofer and a ring radiator tweeter, sized for a medium room. Its measured preference score, a predictor of how neutral it sounds, is 5.09 against 1.62 for the HSU Research CCB-8. The catch: A resonance and associated distortion increase around 800Hz-1kHz creates a “tinny,” occasionally glaring quality on certain instruments and vocals, confirmed both by ear and in the frequency-response and distortion measurements.
The HSU Research CCB-8 is the deeper-bass pick. An easy to drive bookshelf speaker with an 8 inch coaxial driver, good midbass punch and wide dispersion. Its bass reaches about 65Hz before falling 3dB, against 74Hz for the Polk R200. Watch for: Badly unbalanced top end that the reviewer called ‘just a terrible speaker’ outright: a roughly 7dB peak-dip swing in the upper mid/treble causes real listening fatigue regardless of listening angle (tried on-axis, 15 degrees off, and 30 degrees off, all bad).
Buy the Polk R200. It is rated higher for sound quality, and the $100 you would save on the HSU Research CCB-8 does not close the gap.
