Sounds like a great deal!
I have two 5007 and a 1007; many who've tried both the 3007 and 5007 felt the toroidal transformer of the 5007 was worth the difference. Would this be the same for the x008 series?
My 5007 sounds amazing (the second one isn't even opened yet, awaiting the theatre room to be completed). However, I don't know if I'd hear the difference between a 3008 and the 5007
