The M6SDAC has incredibly low distortion, 0.0004% at 20kHz...breathtaking. Stereo separation is better than 120dB. Noise ratio is better than 119dB down....the music is presented on a black velvet background. Linearity is better than 110dB. It excels in every technical area.
The fixed/variable, single ended/balanced output stage employs state-of-the-art components and circuitry which deliver superlative technical and sonic performance and exceptional load driving characteristics and will drive any combination of cable/length/electronics flawlessly.
The headphone amp has the same design philosophy and implementation.
The M6SDAC's immediate sonic impression is of effortless grace and transparency...there is a sensation of communication from the artists that is hypnotic and compelling. It is so musically integrated: the whole sound is sweet and clear; the treble is completely grain free and extended. The bottom end sounds endless with tactile bass dynamics and light speed fast attack/decay. The imaging, as you would expect from better than 120dB separation, is excellent: side to side, image placement, a palpable sense of the recording venue that places the performers in real-time holographic space.
