haha, vinyl has a smaller frequency range than CD. Bad stereo imaging and the list goes on, it is in no way "better" on a 5k rig in comparison.
My live PA is generated digitally, and the audio quality is always so much fuller and clearer in comparison to the DJ`s I have just followed.

RAW dj skill is in the mixing and eqing.
The actual beatmatching isn`t a skill, it`s a mechanical process that gets in the way of making a good mix.
Personally if I could have a tune instantly qued up and beatmatched with some magic piece of kit, I would buy it straight away, because I know and accept it would give me more time to do the important and skillful and artistic part of DJing, ie, the eqing, sorting the mix point, tricks etc.

Anyone and their gran can beatmatch, and a good DJ it does not make.
