Short answer: the KEF Reference 1 Meta. It ranks #3 of 222 bookshelf speakers by sound quality (rated 4.8/5) at $9,999.98 and is still sold new; the Philharmonic BMR (v1) ranks #40 (rated 4.3/5) and is discontinued, so it is only an option used. The Philharmonic BMR (v1)’s replacement, the Philharmonic BMR Monitor, is rated 3.6/5 at $2,200.
The KEF Reference 1 Meta is the more accurate, deeper-bass pick. Extremely accurate bookshelf speakers, with a superb three dimensional soundstage, no harshness, and tightly matched pairs. Its measured preference score, a predictor of how neutral it sounds, is 6.48 against 4.86 for the Philharmonic BMR (v1). Its bass reaches about 52Hz before falling 3dB, against 62Hz for the Philharmonic BMR (v1). Watch for: At roughly $10000/pair, nearly four times the cost of the similarly-sized KEF R3.
Why pick the Philharmonic BMR (v1): A large three way bookshelf speaker with a ribbon tweeter, flat response, broad coverage, and an unusually expansive midrange. The catch: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification.
Buy the KEF Reference 1 Meta. It is rated higher for sound quality; the Philharmonic BMR (v1) is no longer sold new.
