Tower Boss,
I am sure the ML and Nak are both breathtaking. My mention of the ML was not meant to slight your setup. I just thought it had to be mentioned because it is the most visually overwhelming/over the top CDP I have seen. Like your Nak it has three boxes, but the PS is huge and there are 3 cables just to connect it to the transport. Add the PS AC cord, the one for the DAC, the DAC connection to the transport and the fact that the DAC alone looks like a miniature (OK, not so minuature) futuristic building, the transport with its massive power lid and you end up with something that has to be seen to be appreciated.
Your Dragon may well be more advanced and more like the upgraded ML's that came along after my time. All I know is the 30/31 sounded amazing and Beemer is mighty lucky to have the later versions of those beauties. After I left the business I did not make an effort to keep up with the latest and greatest, a wise plan when you no longer have access to that stuff at dealer cost or better and a never ending supply of customers willing to buy your castoffs at no loss. Though I am not saying it is as good, the only machine I have here that has had the same WOW effect on me is the Stax Quattro II I just acquired. Interestingly, it uses a Sanyo transport like the Dragon, not sure which one though.
The TDS1541A was a good chip. My Mission PCMII uses them, but the Stax kills it with its PCM56P's however. Looks like Stax used the PCM1702 in a later DAC. That might be worth a listen!
