I always try to get a best sound that I can afford from vintage, DIY and new components.
I think the vintage audio equipment is underrated because most of modern audiophiles newer have deal with it. In opposite most of "vintage" lover audiophiles started from a new stuff and moved to vintage, because vintage components sound more musical and better value for money.

My philosophy is: 
1. Good dynamic and real instrument tone are most important.
2. Good mid-range - first. 
3. No HiFi-ish highlighted high frequencies and bass. The real acoustic instruments don't sound like this!
4. High sensitivity speakers  
5. SET Tube amplifiers.
6. Idler and direct drive turntables.
