Looking to build a system for under $5k

Should also mention that I listen to a lot of pop, jazz, and fusion.

So many ways to go.

Maybe take a look at member systems here, find one that you like as a reference and ask questions from there to help zero in on something you might like best.

I hate to be the one to say this but if you are looking for a general consensus, you are not likely to find one here. Do a search of of amps, speakers, sources and cables on these forums and you will find literally hundreds of different recommendations for each component.

My advice would be to go out and listen to some Vandersteens (among others if possible) if they float your boat then you may want to start a thread about them and perhaps the many Vandy owners on here can chime in and suggest a suitable amp. I believe there is a gentleman who frequents these forums quite often from Audio Connection in New Jersey and is widely known as the go to guy when it comes to all things Vandersteen.

Best of luck on your new system and welcome aboard there is a lot of useful information on these forums and many members on here with years of experience to draw from.

See these reviews about Schiit Audio components.  In particular note the reviewers comments at the end of the Ygg review.  
(i.e., Ygg>>Rag>>KEF LS50).  

Maybe think Oppo universal player in place of the Ygg to save some bucks.  Used will definitely save you bucks if you can find something that won't need immediate maintenance/repair.

Do try and get out to hear as much gear as you can - "educate your ear", as it were.  

Also, look at some of the budget systems here under Explore (Explore>Virtual Systems>Tags>Budget Minded).

Good luck in your hunt.  Lots of good combinations out there.
