"I was recommended to "Ace Mastering" from a friend who was mixing my CD.

I live in Los Angeles and at first was concerned that working with a mastering engineer on the other side of the world would be a difficult process. My fears were quickly eased. David Senn was fast and efficient expert in his skill. I thought my tracks sounded great before, but after David's mastering, they really shined.  He was very easy to work with and if I wanted to hear a little more of "this or that", he would always happily make the changes and I was satisfied immediately.   I can tell this man knows his craft and has pride in his work. I will use him in the future and recommend him to other people as well."
