SB+ : Improved S/PDIF digital output

Above: SB3 S/PDIF noise plot using a 44.1KHz/16-bit J-test signal
Note the raised noise floor around the test tone, about 6dB worse at 11.025KHz +/-500Hz

Above: SB+ S/PDIF noise plot using a 44.1KHz/16-bit J-test signal
Note the consistent noise floor, 3-10dB lower than the SB3 across the whole plot
Whilst you can clearly see the difference, you'll have to listen for yourself to hear the improvement in your system!
