I have purchased hi res music in the past from a well known (and therefore I assume reputable) online store. It turned out not to even be the recording it was claimed to be (I noticed specifically because I was comparing the hi-res download to a CD copy I had and it was clearly an entirely different performance). When this was pointed out, they refunded, but no explanation was given as to what the other recording was, or why it was incorrect - it wasn’t just a case of mis-identifying the album on the website; they actually didn’t know what the recording was, even after investigating. My impression is that they had not attempted to be dishonest themselves but rather they, too, had been unaware that the recording they were selling was not what it claimed to be.
