Band: opinion spread · Dot: weighted average
Sources split into two clusters. The two lab tests lead the first. Amir at ASR heard 'rather bright' treble that was too much for him until he cut a 550 Hz resonance and shelved the top end down. AUDIO's Andrzej Kisiel measured and heard boosted bass and treble around a lowered midrange, which he calls a 'commercial' response that will impress many listeners. Three owners sit with them: one on Polk's forum found the pair 'too metallic' on classical music through a 40 W valve amp, an ASR owner says you 'can't listen to music to relax', and a Japanese owner coming from B&W calls the sound sharp and short on warmth. The second cluster hears no such tilt. OldTrades calls it the more balanced, refined successor to the Signature S60, though he still trims the treble a notch. AV Watch hears a modern sound that keeps some warmth, a Japanese dealer calls the range well balanced and natural, and kakaku owners on Denon receivers describe it as mild or slightly warm and never tiring.
Measured
ASR's Klippel data (grille off): a resonant peak around 550 Hz and generally elevated treble. spinorama.org puts the deviation at 3.1 dB over 300 Hz–5 kHz and the preference score at 3.69 (5.57 with a subwoofer; 5.75 and 7.33 with EQ). AUDIO's lab shows the midrange lowered across roughly four octaves, from 250 Hz to 4 kHz, with the response inside ±3 dB from 35 Hz to 20 kHz when measured 7° below the main axis.
vs. listeners — Both labs measure a treble lift, yet more than half the weight hears no brightness. Setup explains part of it. AUDIO found the treble falls into line with the speakers pointed straight ahead or toed in only about 15°. OldTrades and a kakaku owner both found the grille softens it. Amir also notes the 550 Hz peak may offset some of the brightness. The Japanese press reviews were arranged with Polk's distributor.
“i do think that this is the better choice it's just more balanced refined version”

“Detailed and rather bright treble response.”
