Band: opinion spread · Dot: weighted average
Sources split. About half hear a balanced, natural and lively tone: Hi-Fi Voice calls it sober and unaggressive, HifiClube more balanced than the S2, and Sound Advice even a little polite. The other half hear a balance tilted upwards — What Hi-Fi and TechRadar call it forward and assertive but enjoy it, Hi-Fi Class says the tilt is plain to hear, and Les Numériques says the maker inflates the top of the spectrum. The split tracks the treble (below), the amplifier and how the speakers are placed.
Measured
No anechoic or Klippel measurement exists. Les Numériques' lab graphs show a fairly even response through most of the range with the treble pushed up above about 8 kHz. Hi-Fi Voice (Clio Pocket at 1 m in a semi-reverberant room, valid above about 200 Hz) finds the response solidly flat to about 5 kHz, with energy rising clearly above that.
vs. listeners — Both measurements show the treble lift, so the 'tilted up' camp has physical backing. The 'balanced' camp is not wrong about its own setups: Hi-Fi Voice, which measured the lift, still heard its cymbals as calmer than the 606 S3's and 603 S3's, and recommends not pointing the drivers straight at the listener.
“civilní, neagresivní prezentace”
Daniel Březina, Hi-Fi Voice (Czech: 'a sober, unaggressive presentation'; McIntosh C2700/MC3500 MkII)
“Sa base technique est très honnête, mais le constructeur prend un étrange plaisir à gonfler le haut du spectre.”
Les Numériques (French: 'its technical basis is very honest, but the maker takes a strange pleasure in inflating the top of the spectrum'; Naim Uniti Atom)
