Excellent Objective Indicators
The R&D target of RED acquires totally new from TRUTHEAR, based on the original excellent objective index of ZERO, the nonlinear distortion of RED is further optimized at higher sound pressure level (>94dB), and its frequency response target curve has bass amplitude response characteristics similar to the public preference curve, while the target curve of CRINACLE IEF_ Neutral is adopted in the frequency band above 1000Hz.
This characteristics provides a punchiest bass without affecting the sound of higher frequency bands; Compared with ZERO, RED is relatively less in dynamic,but still conforms to the characteristics of HRTF, which makes RED very suitable for long listening without fatiguing.
Sonically, The treble of RED is bright without iriating, dispatching a warm, natural and pleasing performance.
