Excerp from review:
The improvement was as obvious as it was shockingly effective. The increase in dynamic range and resolution, the reduction in grain, the improved dimensionality, focus and presence, the distinction between the body of performers/instruments and the enclosed acoustic space, the absence of the mechanical or process related artefacts that separate the reproduced performance from the sense and musical impact of the original event – all were present, all were obvious, but all were also integrated into a magnificently persuasive and natural whole. The v3.0 made the v2.0 sound small, compressed and muted, both in terms of colour and dynamics, which is fairly remarkable given that the v2.0 generally does just that to other record players.
