Short answer: the Q Acoustics 5050. It ranks #71 of 226 floorstanding speakers by sound quality, rated 4.3/5, at $2,499; the PSB Imagine T54 ranks #98, rated 4.2/5, and costs $2,599, so there is not much of a tradeoff to weigh.
The case for the Q Acoustics 5050: Flagship floorstanding tower in the 5000 Series with dual 6.0-inch C3 Continuous Curved Cone woofers, internal HPE tubes, and P2P bracing. The catch: Rating estimated based on 5000 series sibling testing.
What the PSB Imagine T54 does well: Premium 3-way floorstander in the Imagine series featuring dual 5.25-inch woven carbon-fiber woofers, a dedicated 4-inch carbon-fiber midrange, and a 1-inch titanium dome tweeter with neodymium magnet. The catch: Rating estimated based on Imagine series sibling testing.
Buy the Q Acoustics 5050. It is rated higher for sound quality than the PSB Imagine T54 and costs less, which makes it the one to get unless you need something the other one does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Q Acoustics 5050 4.1 to 4.5; PSB Imagine T54 4.0 to 4.4). Treat this verdict as provisional.
