With a separate power supply electrically isolating delicate analogue signals in the preamplifier, this cosmetically-matched dual-chassis reference line-stage preamplifier offers significant gains in detail retrieval over the XP-10 without loss of musical soul. How does this translate into the sonic fidelity you really care about? Instruments and voice are presented in a more refined soundstage, and with better spectral balance. Fine nuances and details, which frequently go un-noticed, now become beautifully apparent -- even in loud and highly complex musical passages.
