I've had the Antares Systems Tube in my set up for about five years or so and while I do like the sounds I can get from this plug-in, I've found that it is one that needs to be used sparingly. For starters, I don't believe it is possible to get a true tube sound from anything other than an actual piece of tube gear, and while this software does a decent job of emulating this warm sound, it is an impossible sound to get without the real thing. So don't think that you can simply warm up all of your tracks with this one plug-in as I don't think that this is meant for or capable of doing this. I do however, use the Antares Systems Tube plug-in for getting slightly fuller and warmer signals here and there when I feel it might work best. It has an overall pretty good sound to it, but you really need to figure out how to use it best before you go and use it on everything. If you are looking for a tube sound, you will not find it here! This is a nice emulator, but is not substitution for real tube gear.
