I have a few key pieces to my system that are from different eras. A Thorens 124 turntable designed in the late 50's, a Scott tuner designed in the early 60's, a Revox reel-to-reel tape player from the 70's. It all fits in nicely with contemporary gear that I also enjoy. I found that the turntable and tuner sound better than the more modern designs I was using, so I went to them for an improvement in my musical experience, not nostalgia.
I also have a 60's Scott 299a integrated amp that I think sounds beautiful, but nowhere near as complete a musical experience as my contemporary Zesto electronics. So I would not say that old is always better than new, or vice-versa.
I'm glad it is all still out there for me to try and decide for myself.
