Short answer: the GR-Research NX-Studio. It ranks #4 of 222 bookshelf speakers by sound quality, rated 4.8/5, at $3,630. The Perlisten A3m ranks #51, rated 4.2/5, at $3,000, $630 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Perlisten A3m: A sealed high output monitor with dual 8 inch woofers and a waveguide tweeter, a great match for a subwoofer in a home theater. 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.
The GR-Research NX-Studio is the better-sounding choice. A DIY kit bookshelf speaker with a ribbon tweeter for wide open, detailed sound, superb imaging, and tight, fast sealed bass. The catch: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.
Buy the GR-Research NX-Studio. It is rated higher for sound quality, and the $630 you would save on the Perlisten A3m does not close the gap.
