There are several methods employed by DAC designers to process the incoming digital data stream and extract the audio and clocking frequency. Some designs rely on an internal clock built into one of the digital chipsets, whilst others rely on an (expensive) external clock. Debates have raged for ages as to which method is the best.  The Caiman MKII Firmware SEG-42 attempts to take that decision process away from the DAC designer or after-market clock designer, and hand you control of the incoming data process instead. The Caiman MKII is now transformed by the SEG-42 Firmware into an even more potent DAC. With its unique ability to select different data processing options, the Beresford DACs are the only DACs with this highly advanced feature. With just the press of a single button you can get an instant idea of the effects that a different data processing method makes to the audio signal.

Fitting instructions: 1. Undo the four screws at the side of the case. There are two each side. 2. Remove the top cover of the DAC. 3. Look for the chip in the socket on the PCB right behind the LEDs. 4. Use a thin flat bladed screw driver to carefully lift the chip up half way on one end then half way the other end. Then repeat the procedure. 5. Remove the new chip from the plastic holder by using a flat blade screwdriver to push the chip out of the plastic holder. 6. Remove the aluminium foil from the chip, making sure not a single piece remains stuck to the chip. 7. Make sure that you fit the chip the right way round. The writing on the two chips should be the same way round when you do the swap over. The writing goes from left to right. 8. Remove old chip and replace with new one. 9. Put the original chip in the plastic holder that the new chip came in. Then put that away safely in case you need to revert back to it. My suggestion is to sellotape it to the side of the inside of the top case. But if you do that, dispose of the aluminium foil so that it doesn't accidentally short out anything inside the DAC. 10. In case you are not sure of something, get back to me for help before continuing!
