You can buy his stuff directly from eBay where is rating is 100% positive after 666 feedbacks. I don't think you can go wrong. I've never heard of anyone having a problem with them, which is not to say it is unheard of. He has a new DAC called the Havana that he's pushing to Audiophiles at a significantly higher price. It uses a different DAC chipset (Burr Brown PCM56P (16 bits) DAC chip). Has anyone tried this DAC?
