Popping a sample of the X-DACV3 on my test bench, I measured a maximum output of 2.2V, this to specification and only 0.8dB higher than the CD standard's 2V RMS. Its output impedance was a low 48 ohms, and, unlike Musical Fidelity's X-24K, which I reviewed in February 1999, the X-DAC didn't invert signal polarity.
