I would enjoy a 70s separates system with analog meters and such. Kenwood even made a matching oscilloscope that you could rack with your integrated amp, tuner and “de-noiser”.
I also fully realize that it’s purely for aesthetics, most of those old amps don’t sound as good, and even if I got a McIntosh or something, my ears aren’t going to pick up much nuance after years of high volume shows. I can justify spending a few hundred, but not a thousand plus. And anything like that is going to need service, and this is a terrible time to buy anything “vintage”, price-wise. So, probably not going to happen.
I do go to estate sales and secondhand stores every week or so just to keep an eye out.
Someone on craigslist near me has a set of Rectilinear Lowboys, which would be a matching speaker option for such a system, but too big for my little 11x12 living room.
