Costco and KA bowl size
If I'm not mistaken, Costco no longer offers either the five quart or six quart KA mixers. Instead, they have a 5.5 quart model, which I suppose my be unique to Costco, I don't know. It looks like a five quart to me, go figure.
As I recall, the Epicurean has metal gearing but the gear housing is plastic. Might be why it is quiet. The 5 qt HD Pro claims to have "all metal construction", however, I have not peeked inside to see if the gear housing is plastic or metal. As I said before, the ring gear on a planetary gear set shoulders most of the load, which is why KA may have been able to get away with plastic gear case housings. But I suppose if one is intent on mixing a batch of tennis shoes in a home mixer, anything can and will fail.
Oh, and the 5 qt model also has the burnished attachments and the spiral dough hook. The Epicurean has the older powder coated attachments as well as the C hook design. Not a big deal to me.
Of course, if one wants the absolutely "perfect" kitchen, one might want to procure one of these beasts. At 1100 watts, and 20 qt capacity, it probably could keep a small restaurant kitchen mixing it up indefinitely. And, it's "only" $1500!!!
PS-For me the perfect kitchen is the one that keeps one's family and friends well fed and happy. And a simple hand mixer can do that.
