Sonic Similarity Analysis
Direct lineage through designer Sandy Gross who founded both Infinity and GoldenEar. Both use advanced tweeter technology (EMIT planar vs folded ribbon) for exceptional high-frequency detail and air. Similar emphasis on transparent midrange, wide soundstage, and dynamic bass response from dual-woofer towers.
