Suggestions for first hifi system

Kimber Kable Tonic interconnects. good quality and affordable (approx $65 for .5 meter).

Kimber Kable 4vs speaker cable. (approx $110 for 10ft pair).

check out on audio advisor website.

Sounds like a nice start for a first system.
The Kestrels are great at rendering a life like soundstage, I know as I currently have two pair of them. Use solid core cables to get an extra three dimensional quality. Don't need to be expensive, low end Audioquest cables work well with my Kestrels.
Can't speak to your other components as I haven't heard them.

Bluejeans cables and ICs. I like these guys because they show you exactly what you are getting.
