It takes time to get a good master even with some of the best plugins and monitors. AAMS will give you a great starting point, and is well worth the money for those on a budget or musicians do not have the time for mastering. In my opinion AAMS is very good A+.A few people on the net have made the comment on the length of time it takes to run the auto feature. Well AAMS is nothing compared to the amount of time it would have taken to do a mastered version of a song at the same quality AAMS software produces! Unless your some kind of mastering wizard you can't compare. What impressed me the most was how the auto feature applies compression. Either way if you like it or believe it or not AAMS is a great software!
