Yes there are now some prestigious users of Leedh. However whether or not dCS adopt it will only be revealed when the new generation range is launched . So this topic now really belongs to the speculative Vivaldi successor rumours thread:
For my part it attracts me as the preamble to the Leedh patent indicates that they are aware of the audible aberrations that upsampling can bring and which is hardly discussed otherwise. As many here are aware these disturb me to such a degree that I cannot listen to upsampled programme or at least to the result of using either dCS’ transport or Upsampler conversion and I therefore have the clone mode permanently set to lock. Yes, I realise that I am an outlier on this.
