Hi David-
A.T. is pretty much right-on. Many folks use anlog gear going in, but many don't. A lot of us use it in post during mixing. So, your question is fair about not clogging the source.
The thing with analog gear is that it really sounds smoother. It's subjective, and there are a billion threads about the debate between analog and digital. Without digital and software based recording, most of us would never have been able to become recordists. In addition, the ability to edit and tweak things in the digital domain is unsurpassed. But the analog gear does something that is almost not describable. The words that people generally use are warmer and smoother.
I have personally been accumulating analog gear for a few years now, and there is honestly an audible difference. However, depending on your taste, you might night like it better. That's the key. Many on here have discussed the fact that people raised this side of say 1990 will mostly have been raised on digital recordings. Thus their frame of reference may be the digital sound. But it depends largely on what music they listen to. As you noted, many a producer and recording engineer use analog gear for acts that have the money to be recorded by such folks. Thus, it's possible that the recordings that even a newer generation likes was recorded using analog gear.
So to me, most of the analog gear sounds better to my ears, but not everyone will agree. Music is subjective. We don't all like the same material, and we won't all like the same qualities that both analog and/or digital have to offer. If you have the opportunity, listen to some recordings that you would know were recorded differently. I don't know your tastes, but there is likely a song that was recorded pre 1990 that you might like. It may also have been re-recorded as a cover by someone later on. If you can find something like this, you can judge yourself.
Remember, in the end neither is "better." Your ears will tell you which one sounds better to you.
