Musical Fidelity Nu-Vista 3D CD Players

Product Description

First we made a critical analysis of why normal compact disc players sound different to SACD machines. The main difference, which you can hear, measure and easily identify, is in the HF performance. Noise ratio and dynamic range make a small difference. It's commonly believed that the extended frequency response of SACD, up to about 100kHz, is the big reason why SACDs sounds different to ordinary CDs. But over the age of 25, most people can't even hear up to 18kHz, and the older you get, the worse this gets. People in their sixties or older can hear the difference between SACD and CD, so what they're hearing can't be down to the extended HF response.

Our research has shown that the audible differences between CD and SACD are caused by in-band non-linear distortions, group delay, phase-shifts and intermodulation anomalies.

So we have engineered the Nu-Vista 3D to ensure that it has dramatically better HF performance than ordinary CD players in distortion, phase shifts, group delay, inter-modulation, non-linearities and noise ratios. The result is that in-band (20Hz to 25kHz), the Nu-Vista 3D actually measures better than SACD.

To achieve this, the Nu-Vista 3D up-samples 24-bits at 96kHz. This takes all digital error artifacts out of band so they're not a factor up to about 35kHz. As a result, we were able to simplify and re-design the digital and analog filters to be far above the audio band, so that their phase shift and group delay is out of band. This allows for a reduction in overall feedback and simpler circuitry.
