it looks like the Viking is made by DeLonghi (Kenwood). Is it made in the UK? It looks like a heck of a mixer. Not really sure why people are so concerned with the noise. You are cooking, not reading or meditating. I have worked in hotel and resturant kitchens, now there is some serious noise. I love my Kenwood, wouldn't trade my KA Pro6 for anything but a Pro 600, and wish I had a 12qt Hobart. I will have to give the Viking a closer look-see.
Where you are is where you belong, it is where you are going that you can change
