Actually, Lampizator, who exposed the use of the cheap DAC in the 66, described the build quality and internal layout as "fantastic" and the sound was well worth the price. "would be a 10/10 to people who don't know any better". A left-handed compliment to be sure, but still high praise coming from a person who is claiming the company is perpetrating a fraud. Additionally, later in the article, he talks about an upgraded 88 with a new DAC.
Read for yourself. Not that his opinion means anything to you, but when you hear these horror stories, you should see for yourself where they're coming from.
