The example I was thinking of is the way I put my reel to use; record vinyl to reel for convenience, this is constant with few variables, no matter how good the vinyl rig is, the reel playback will sound better.
I use 2 track recorded at 7 1/2 ips. The vinyl is recorded tape out on pre, to tape in on reel. As I explained, the reason the vinyl sounds better on playback, is because the sound is bigger because of the larger tape heads of a 2 track, not only does that mean more detail, but it also adds depth to the sound stage.
I know that's not the same situation as you might expect from the original statement, but I record my vinyl to reel for convenience, and that's what I get. When you compare different turntable setups to different reels, that's not valid because no constants have been stated.
