Old cars are nice to look at, fun to drive occasionally, but if you are going to compete at the track, you are going to go new, and that new "daily driver" is more comfortable, handles better, faster, and is better on gas or at least 3 out of 4
The difference with audio equipment is that it is personal preference and having a personal preference for "old" equipment does not necessarily confer a loss or detriment to any of the other aspects of the experience like an old car. Definitely digital is far more user friendly than vinyl, and I would have a really hard time giving up remote volume control, but other than that, an old amp or new amp, old turntable/new, etc. takes the same effort.
On DACs, there is a following that is essentially going back 30 years in tech, and they are happy about it. Others like Erik lean towards a different preference.
Oh collection? About 5 or 6 years ago, I came to the conclusion I had too much stuff in my life that was just "there" but not really making me happy and taking up space and time. I scaled back to what I use and got rid of the rest. I can't say I miss it at all. I had a collector mentality in the past. I don't any more.
