Sometimes yes, sometimes no. I have a large collection of 10 inch reels, all professionally recorded from LP's, some almost twenty years ago. Some were at 15 ips, 7.5 ips and 3.75 ips. Some are two track stereo, other 4 track stereo. Some of these tapes were produced by various broadcast music services like Drake, Media General. Others were produced by the government, e. g. AFRTS. I have many of the source LP's and I have compared the quality of the tapes with the LP's. Again, some of the tapes are great, others trash. In general, most do not have any artifacts. I've recorded many of my LP's with a high end sound card in my computer using Steinberg software. Again, some times the tapes shine other times not. A lot has been written about the Drake production methods and the tight quality control that was used. Most of what we heard on FM radio were Drake tapes. So, if the LP's were well recorded and you use a top line rig, they always win.
