Short answer: the Perlisten A3m if sound quality matters most, the GR-Research X-LS Encore if price matters most. The Perlisten A3m ranks #43 of 130 bookshelf speakers at $3000. The GR-Research X-LS Encore ranks #83 at $1300, $1700 cheaper.
What the GR-Research X-LS Encore offers: An amazing value, especially if you managed to snag one of these built by AV123 in the early 2000s for $200-300. CEA2034 spinorama shows a generally flat on-axis response, especially in the listening window. Predicted in-room response is generally smooth and on-target. Distortion at 86dB SPL/1m is pretty clean above 200Hz. Watch for: A slight depression in the upper bass and some peaking in the lower bass shows up on-axis, along with directivity error in the crossover region. Vertical directivity requires staying within about 20 degrees of the tweeter axis. At 96dB SPL/1m distortion becomes “rather unhappy,” with bass distortion, a possible woofer issue around 2kHz, and a tweeter problem above 7kHz. As a DIY kit, it requires building the cabinet and crossover yourself.
What the Perlisten A3m offers: 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 3.39 to 6.42 with a subwoofer. A sealed cabinet, two 8-inch carbon-fiber woofers, and a controlled tweeter waveguide make this a high-output monitor. Watch for: 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 $3,000/pair.
