Not at all the same, but a few years ago, before I had a SACDP and before I knew anything at all about SACD, I saw what I felt was an expensive MFSL hybrid for sale on ebay. I really wanted an "audiophile" copy of that CD but I didn’t know for sure whether hybrid meant compatible with red book CDPs, so I messaged the seller and asked him and I got no response. I did some research and found that it would play on my CDP, so I then trued to buy if from that ebay seller, but he had me blocked.
I bought it from another ebay seller, but I always wondered what I did that pissed that guy off.
