What I am looking to do is to add to the range. The BM can produce even better results with a few mods. )That reminds me to start a new thread on some mods as requested by a many people.) It can also already process in asynch mode based on the test FW that I have been trying out. More about that another time. I refer to it as the firmware, but in reality it is the whole operating system run by a MCU. At the moment I am running it at 20MHz, but I am looking to see if it is possible to upgrade it to a higher speed with a more powerful central core.

As for the additions to the range: it has more parts and would have to be wider than the BM in order fit in all the extra bits. I am considering using the new info to make two DACs. One would be just optical and coax inputs, whilst the other would have a USB socket as well. The plan is to keep the retail price (excluding VAT etc.) below £250, without compromising the performance.
