I have been a long time waves customer for 10+ years, and have most of their coveted plugins(I.e Ssl 4000 e channel, Api 550, Faichild, 1176, J37 tape, etc) which are pretty good, so didn't see what was all the fuss about universal plugins, until I heared a side by side comparison of the hardware with uad. Wow, was my first impression. They sounded almost if not identical in a a/b. They had me sold after that. All of the plugins in my bundle sound excellent. I hear a significant difference in my mixes like night and day. Now I see why universal audio is so loved. I'm very pleased with my purchase. I'm not really a review guy but this is a really good upgrade for your home studio guys, trust me. One of the best investments I've made in a while, thanks American musical.
