I can appreciate Dubfire’s setup because i’m building a similar one myself, but im nowhere near as good with it as he is, even though his music isn’t really my style
Nothing new about using loops. Most techno on vinyl was just loops and the djs normally used 4 technics to perform.
3 TTs and a 909 = rock the dancefloor 
it’s whatever floats your boat.
There’s definitely in techno at least two types of djing now. One that just plays track to track old school, which is great if done right, then there’s the others that are basically remixing tracks on the fly.
Personally I think both have there own merits and just add to the pool of diversity in the techno scene
even the big boys check their email too much.
