Short answer: the Philharmonic BMR Monitor. It ranks #134 of 222 bookshelf speakers by sound quality (rated 3.6/5) at $2,200 and is still sold new; the Pylon Jasper Monitor 18 ranks #186 (rated 3.0/5) and is discontinued, so it is only an option used.
The Philharmonic BMR Monitor is the more accurate choice. Three-way bookshelf speakers with premium drivers, a well-built cabinet and extremely wide dispersion for a broad soundstage. Its measured preference score, a predictor of how neutral it sounds, is 6.02 against 4.72 for the Pylon Jasper Monitor 18. The catch: A 1-2dB bump around 2-3kHz creates a “glare” on vocals, guitars, and strings that the reviewer noticed consistently across many tracks.
The case for the Pylon Jasper Monitor 18: A premium Polish monitor with ScanSpeak drivers, lively midbass punch, wide dispersion and an attractive finish. The tradeoff: Sounds notably bright, thumpy, and fatiguing pointed directly on-axis; needs about 30° of toe-out to bring the high-frequency lift into better balance.
Buy the Philharmonic BMR Monitor. It is rated higher for sound quality and still sold new, while the Pylon Jasper Monitor 18 is discontinued.
