Short answer: the Ascend Acoustics Sierra-LX. It ranks #37 of 216 bookshelf speakers by sound quality, rated 4.3/5, at $1,598; the Perlisten A3m ranks #52, rated 4.2/5, and costs $3,000, so there is little reason to consider the other one.
The Ascend Acoustics Sierra-LX is the more accurate, deeper-bass pick. Very neutral, flat frequency response: within about plus or minus 1.5dB ignoring one narrow dip. Its measured preference score, a predictor of how neutral it sounds, is 6.63 against 4.30 for the Perlisten A3m. Its bass reaches about 47Hz before falling 3dB, against 85.8Hz for the Perlisten A3m. The tradeoff: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels.
Why pick 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 catch: 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-LX. It is rated higher for sound quality than the Perlisten A3m and costs less, so only choose the other one for a particular feature it does better.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.

The Two Speakers In Full
Ascend Acoustics Sierra-LX: $1598 per pair Ascend Acoustics $1598 eBay
Same family: the Ascend Acoustics Sierra 1 v2 (smaller bookshelf, rated 4.7/5), the Ascend Acoustics Sierra-2EX V2 (smaller bookshelf, ranked lower, 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). See every Ascend Sierra generation.
Pros: Very neutral, flat frequency response: within about plus or minus 1.5dB ignoring one narrow dip. Bass extension down to about 40Hz in-room despite the compact size. Wide, well-balanced soundstage (~60 degrees). Solid build quality with a laminated bamboo cabinet. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 81dB.
Cons: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels. Noticeable midrange distortion becomes audible above about 82-83dB SPL. A narrow dip around 3.5kHz on-axis in larger rooms without sidewall reflections: toeing the speakers out 10-20 degrees fills it in, but adds some brightness to the treble. Sensitive to listening height: sitting even slightly above or below tweeter level noticeably shifts the tonal balance.

Perlisten A3m: $3,000 per pair Perlisten $3,000 eBay
Same family: the Perlisten A3t (smaller floorstanding, estimated 4.2/5), the Perlisten A4t (larger floorstanding, estimated 4.3/5) and the Perlisten A2s (surround, estimated 4/5).
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.
