Short answer: the Ascend Acoustics Sierra-2EX V2. It ranks #43 of 203 bookshelf speakers by sound quality, rated 4.3/5, at $1,748; the Perlisten A3m ranks #52, rated 4.2/5, and costs $3,000, which makes this an easy call rather than a real tradeoff.
The Ascend Acoustics Sierra-2EX V2 is the more accurate, deeper-bass option. A RAAL true ribbon tweeter is paired with a custom SEAS Excel Curv woofer, with the crossover optimized against Klippel NFS measurement data. Its measured preference score, a predictor of how neutral it sounds, is 5.88 against 4.30 for the Perlisten A3m. Its bass reaches about 58.6Hz before falling 3dB, against 85.8Hz for the Perlisten A3m. Watch for: On-axis response is relatively uneven, with an average deviation of about 0.45dB, so a listener sitting dead center may notice more unevenness than with smoother AsciLab or Ascend towers.
The case for the Perlisten A3m: Manufacturer data shows a narrow 1.8dB reference band, 0.305dB on-axis average absolute deviation, 0.457 listening-window smoothness, and a rated 111.4dB peak at 1m. The tradeoff: The low-quality vendor Spinorama data measures only 85.8Hz at -3dB, 74.1Hz at -6dB, and 55.7Hz at -12dB, conflicting with Perlisten’s much deeper in-room extension claim.
Buy the Ascend Acoustics Sierra-2EX V2. It is rated higher for sound quality than the Perlisten A3m and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Ascend Acoustics Sierra-2EX V2: $1,748 per pair Ascend Acoustics eBay
Older model: the Ascend Acoustics Sierra 2 (ranked lower, rated 3.7/5).
Same family: the Ascend Sierra 1 v2 (smaller bookshelf, rated 4.7/5), the Ascend Acoustics Sierra-LX (larger bookshelf, ranked higher, rated 4.3/5), the Ascend Acoustics Sierra Titan Tower (floorstanding, rated 4.4/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5).
Pros: A RAAL true ribbon tweeter is paired with a custom SEAS Excel Curv woofer, with the crossover optimized against Klippel NFS measurement data. Listening window smoothness measures 0.45, a moderate but usable figure for a compact standmount. Pairs are hand matched within +/-1.5dB and shipped with their own individual frequency response printout, backed by a 7 year parts and labor warranty from direct USA assembly in Orange County, California. Measured bass extension of 58.6Hz (-3dB).
Cons: On-axis response is relatively uneven, with an average deviation of about 0.45dB, so a listener sitting dead center may notice more unevenness than with smoother AsciLab or Ascend towers. Bass extension is modest for the price class at a measured 51.3Hz at -6dB. Ascend sells direct only, with no dealer network or third party retailers for an in person audition.

Perlisten A3m: $3,000 per pair Perlisten eBay
Pros: Manufacturer data shows a narrow 1.8dB reference band, 0.305dB on-axis average absolute deviation, 0.457 listening-window smoothness, and a rated 111.4dB peak at 1m. Its preference score rises from 4.30 to 7.34 with a subwoofer. A sealed cabinet, two 8-inch carbon-fiber woofers, and a controlled tweeter waveguide make this a high-output monitor. Measured bass extension of 85.8Hz (-3dB).
Cons: The low-quality vendor Spinorama data measures only 85.8Hz at -3dB, 74.1Hz at -6dB, and 55.7Hz at -12dB, conflicting with Perlisten’s much deeper in-room extension claim. A 3.70 sound-power directivity-index standard deviation and 0.295 predicted-in-room smoothness are merely average. It is large, heavy, 4-ohm nominal, and expensive at $3000/pair.
