I have been told that the Blendtec Stealth is the top blender on the market noise wise. I am curious if that is true, though. Is the Blendtec Stealth really quieter than the Vitamix Quiet One? Also, How much quieter is the Blendtec Stealth than the Blendtec Q-SERIES? Are there other blenders out there better than these? I am also interested in lifetime of jars, motors, and warranties. ease of operation is not a big concern, and neither is price as they are all right around the same price mark (maybe not the Q-SERIES, it is considerably cheaper, but still up there). I really want to know how they all compare in NOISE level. Sound is my biggest concern.

1. Is there a big difference in the sound of the stealth and the sound of the quiet one? Is the difference even noticeable while blended an ice coffee?

2. Is there a big difference in the sound of the stealth and the sound of the Q-SERIES? Is the difference even noticeable while blended an ice coffee?

3. Are there other blenders out there better and quieter than these blenders that I mentioned?

Anyone with knowledge about these blenders or other top of the line blenders, please feel free to leave your comments. I want as much knowledge as I can get about them.

Thanks, Austin
