What's the best sounding aircraft you ever heard?

This came to mind when I heard a RAF VC-10K overflying my house at some 1000
feet AGL at full steam. What a sound! The VC-10 both looks and sounds
powerful. Also, the piston Yak-52 I heard a few days ago...unbelievable,
such a powerful and awe inspiring sound. The only thing I regret is never
hearing a DC-6 at full throttle; watching a documentary on ConAir
firefighting services today (on Discovery Science) I heard one pilot remark
that those 76 cylinders at full power sound 'like a Hell's Angels funeral'.
