Short answer: the PS Audio Aspen FR10. It ranks #87 of 228 floorstanding speakers by sound quality, rated 4.2/5, at $12,000. The DALI Rubikore 6 ranks #195, rated 3.3/5, at $8,000, $4,000 cheaper, not enough of a saving to outweigh the sound-quality gap.
The PS Audio Aspen FR10 is the better-sounding choice. Large floorstanding speakers with planar midrange and tweeter, extremely wide dispersion and bass that works close to the rear wall. The catch: At roughly $12000/pair, expectations are high, and the reviewer found some measured shortfalls relative to that price.
The DALI Rubikore 6 is the more accurate pick. Large floorstanding speakers with an unusual four driver layout, low distortion, solid bass and wide dispersion for an enveloping soundstage. Its measured preference score, a predictor of how neutral it sounds, is 5.27 against 4.08 for the PS Audio Aspen FR10. Watch for: On-axis, the treble sits 3-5dB above the midrange (especially around 4kHz), giving a sibilant, hot top end that the manufacturer itself recommends compensating for with 30° of toe-out (firing the speakers straight into the room rather than at the listener).
Buy the PS Audio Aspen FR10. It is rated higher for sound quality, and saving $4,000 with the DALI Rubikore 6 does not make up for the sound-quality gap.

Measured Differences
- Tonal accuracy above the bass: with a subwoofer taking the low end, the DALI Rubikore 6 scores 7.0 against 5.4 for the PS Audio Aspen FR10 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
- Efficiency: the DALI Rubikore 6 is rated at 86.4 dB sensitivity against 84.4 dB for the PS Audio Aspen FR10, so it plays as loud with roughly two thirds of the amplifier power.
