The clock and opamp upgrade has provided another definite improvement in the clarity of the sound. I’m not good at explaining but it just sounds more natural and less fatiguing, more ‘live’. Bass and high frequencies are very noticeably improved.

Once again I am really pleased with the quality and value for money. The only thing I would prefer is for the plug/socket connections for power and clock output to be left out so the installer can solder wires directly to the board.
