I picked my second system integrated amp and speakers using YouTube. If I wasn't happy, I could have returned them, but I was happy and kept them. of course, the recording has to be very good, and my computer speaker setup is good (neutral sounding ). A bad recording is useless. It helped me get an idea of the basic qualities of the equipment. I had to listen to many demo's to find the good ones to use that sounded similar. It wasn't easy, it took a lot of time. When I set the system up, it sounded like those similar sounding demos I used. Call me crazy or lucky, but that's what happened.
