My impression can be desribed by one word..... Wow!!
Compared to the sr007a, the sr009 definately sound clearer and more spacious. Female vocal performance is sublime on these cans.The only redeeming quality that sr007 has is its comparatively more laidback and warm sound. However they are not too different in sound characteristic to justify owning both of them. SR009 is good enough to replace SR007 totally as your main cans imo.
As reference i list my equipments
