Beginner looking for guidance into tube sound.

Hello all, I am looking for some input on the best way to add tubes to my current mess. I currently have what I am sure everyone here would consider barely a step up from my parents zenith HI-FI circa 1977. please keep in mind I am lucky if I can afford to look in the window of an actual audio store. 
I currently have a Peachtree nova 300 and a Marantz CD player and a pair of monitor audio silver 500 speakers. A friend gave me a blue sound node 2i also. I have always wanted a tube powered amp. I see these Chinese amps like the Muzishare X7 and Willsenton R8 that have lots of great reviews. Or maybe a tube DAC. Then I see the Black Ice for ss-x. Each having less tubes respectively. Not sure how much that matters but I would think the more tubes the more tube sound one could expect. I would like to be in the $1000. range but would go to $1500 if I had to. My goal is to find the best most cost effective way to enter the tube world.
