Mola Mola is an extremely small company and Bruno Putzeys is the heart and soul of the company. Mola Mola's DAC, while having a very small footprint, is extremely complex. I am not surprised that it is late. On the other hand, the delay may be caused by an external factor, like it happened on the Kaluga amp, where the construction of the casing by external suppliers turned out to be challenging.
Regardless, Putzeys is a major luminary of the industry, and his work/product is worth following... Patience ever remains golden.
