I think I've decided to go with a new system, not vintage.
Define "New" and "Vintage"
There are many AV receivers from the last 20 years available second hand for under $50 with a remote. The benefits are:
1) they can be used for stereo or surround sound should you want to pursue that, later
2) most have decent DACs
3) they usually have a subwoofer output should you want to go that route
4) Many have DSP for room correction (Audyssey, DIRAC, etc )
5) they have FM tuners
6) most have Bluetooth, so you can wireless stream music or radio from your smartphone
7) they can connect to your TV to enhance the sound
8) they have headphone outputs
9) you can later upgrade as your budget allows and as you become more knowledgeable
I would recommend putting most (80-90%) of your money into speakers because ultimately that is what you will be listening to and make the biggest difference to YOUR ears. Get out and listen to as many speakers as practical. Remember that anonymous people who post on the internet have very very different preferences in sound and hearing abilities. There is no one speaker that pleases everyone and there is no "perfect" speaker.
You can check locally on Craigslist or garage sales. Ask for a demonstration. Bring or request music that you are very familiar with. Depending upon where you live there may be a reputable company in your region. For example in Utah there is Tektondesign.com and ZUaudio.com In SoCal HsuResearch.com Some offer 60 day risk free trial in your home.
Finally, avoid vinyl and CD unless you already have a large collection. Streaming is the way to go.
