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.

Hey Alex,
What a great looking system you have made!  I also remember your discussions on Jeff Day's site.
Did you change your crossover to N1500 after using the WJ?  Why did you make the change?
I am using modified WJ on my Altec Valencias.
