On a whim I combined A23 ICs with Artisansilvercables pure silver cables via fixed y- adaptors between a Zodiac Platinum DAC and a Wavac EC300b amp. The result was a significant increase in spatial resolution with slightly increased treble. The A23 cables have great resolution with slight treble reticence. The pure silver cables have beautiful colour, especially on strings but with a slight sibilants and strident treble. The combo seems a happy marriage of the virtues while loosing the foibles. I fully endorse the method and will next try it on the Zodiac‘s 10m BNC clock cable
