At least Little Dot offers a refund for the purchased Q's. I say, return it and then re-buy it once they have sorted the DAC-portion out. sword_yang already clearly stated that the Q was developed as an Amp first, then rushed the DAC section due to pressure from some loyal fans. They could either improve the DAC part or remove it completely to focus more on the already-excellent amp.
I don't think this really affects the reputation of LD here. Mochan might be a bit vocal on the Q's problems, but at least his voice was heard and Little Dot offered both a refund and a guarantee of improvement from this product. Hope to see the newly-revised Q to hit retail very soon.
