The LF-A does sound epic, but to me its muffled by its price tag. Either way a really cool car.
But I just love the Zonda and CGT, especially when you hear that perfect CGT downshift.
But there are some other cars that sound incredible as well and dont get a whole lot of credit for it.
Maserati Gran Turismo S
Maserati Quattroporte Sport GTS
*ROFL at the lame SRT4
Aston Martin DBS
