Short answer: the Sonus Faber Sonetto III G2. Both are rated 3.2/5 for sound quality (#201 and #202 of 226 floorstanding speakers), and the Sonus Faber Sonetto III G2 costs $5,000 against $6,000 for the Atlantic Technology 8600iLR, and with sound quality even, the cheaper one is the better buy.
What the Atlantic Technology 8600iLR does well: The 2024 replacement for the Atlantic Technology 8600eLR at the same price, with stronger woofer motors for more output and deeper bass, the tweeter and mids moved to ear height and tighter-tolerance crossover parts. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the Sonus Faber Sonetto III G2: The slimmest Sonetto G2 tower, a 2.5-way with the range’s 1.1” DAD Arrow Point tweeter, a 6.5” midwoofer and a 6.5” woofer that adds output only in the bass, which is rated to 38Hz. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sonus Faber Sonetto II G2, which showed an uneven listening window (a 4.25 Spinorama preference score).
Buy the Sonus Faber Sonetto III G2. Both are rated the same for sound quality, and it costs $1,000 less than the Atlantic Technology 8600iLR.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Atlantic Technology 8600iLR 2.8 to 3.6; Sonus Faber Sonetto III G2 2.8 to 3.6). Treat this verdict as provisional.

Atlantic Technology 8600iLR: $6,000 per pair Estimated Atlantic Technology eBay
Older model: the Atlantic Technology 8600eLR (ranked lower, rated 3.1/5). See every Atlantic Technology 8600 generation.
Same family: the Atlantic Technology 8600iC (center, estimated 3.4/5).
Pros: The 2024 replacement for the Atlantic Technology 8600eLR at the same price, with stronger woofer motors for more output and deeper bass, the tweeter and mids moved to ear height and tighter-tolerance crossover parts. Two 8” woofers and two 8” passive radiators are rated from 30Hz (±3dB) at 93dB sensitivity.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Secrets of Home Theater measured the Atlantic Technology 8600eLR with an upper midrange brightness that the update may not fully fix, and at 40 kg per speaker it is heavy.

Sonus Faber Sonetto III G2: $5,000.00 per pair Estimated Audio Advice eBay
Same family: the Sonus Faber Sonetto I G2 (smaller bookshelf, estimated 3/5), the Sonus Faber Sonetto II G2 (larger bookshelf, rated 3.1/5), the Sonus Faber Sonetto V G2 (larger floorstanding, ranked higher, estimated 3.3/5) and the Sonus Faber Sonetto Center G2 (center, estimated 3/5). See every Sonus Faber Sonetto generation.
Pros: The slimmest Sonetto G2 tower, a 2.5-way with the range’s 1.1” DAD Arrow Point tweeter, a 6.5” midwoofer and a 6.5” woofer that adds output only in the bass, which is rated to 38Hz. Sensitivity is 88dB, and the concrete base improves stability.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sonus Faber Sonetto II G2, which showed an uneven listening window (a 4.25 Spinorama preference score). The 4 ohm load needs an amplifier comfortable with low impedances.
