FWIW, many years ago, I had a high-end Pioneer PD-95 transport with the stable platter drive. It was built like a tank with an internal faraday cage. It was beautiful to look at. But, the sound was very dry and analytical. I sold it for a cheaper, better sounding, custom-modified transport with better processing and clock. No stable-platter. It just died a couple of weeks ago. So, Ive been looking for a replacement.
I was researching the Audio Alchemy DDS Pro, also. I ran across
this thread. It seems that the board might have a power/capacitor issue. Fortunately, the laser assembly, PEA1179 is still available from Pioneer. Unexpectedly, on a local Craigslist, I found an AA package including the DDS III, DTI and DST. Took a chance and bought the package. The three units are linked together ahead of my old DAC. My music sounds better than ever. LOL. I read somewhere that the AA DDS III has a Sony CD drive. So, if you find an Audio Alchemy transport, you might want to check out the DTI as a clock. I did hook up the DDS III directly to my DAC and it does sound pretty good. The DTI bumps it up a little more.
