I don't know if it was a direct comparison but someone emailed me lately saying my EVS amp was "better than a friends sig 30". If you call or email me I can give you his email address and you can communicate directly with him. He was quite impressed with the amp (even compared to his two $10,000 monoed Jadis Defy 7s) that a customer brought over to his house.
