Help! Baffled by Electro house lead

[Armitage]

Greetings everyone. Im a total forum noob, so im sorry if ive posted this in the wrong place or anything like that.

I'm having a lot of trouble recreating a certain synth lead sound i heard recently, I cant quite make out what types of waves/synths/instruments are being used.
I need someone with a more finely tuned production ear to point me in the right direction as i dont even know where to start really.

Here is a link to the tune. Skip to 2 mins 55 secs to hear the lead in full swing.

As im sure you can hear, It sounds like there are 2 or 3 seperate instances of whatever synth is being used at different octaves etc.
I've had some luck with the TAL Elek7ro VST in Ableton by layering 3 instances and using saw/sine waves but what i have sounds a bit like the Deadmau5 "Ghosts n Stuff" organ type sound and lacks the punch or whatever this lead sound has.

Cheers
