When we moved into the house in Brossard, we fully intended to put in a "dream kitchen" with high-end appliances with dual ovens and a gas (or induction) cooktop. Since the range crapped out we thought again about doing this, so I started pricing high end equipment from Dacor, DCS (my preference), Wolf, Thermador and Viking. The better-half's cousin has a huge Viking in her house in Connecticut and having used it, I can attest to its quality.
But the pricing...ouch! the best deal on a DCS 30" dual fuel was $4500, with Dacor and Viking even more expensive. Even "mid-high-end" Bosch was hovering around $2,200 as with the mainstream brands like KItchenAid Architect or GE Profile.
So aside from looking like it belongs in a commercial kitchen, what justifies double and triple the price for a high-end appliance? Certainly not the warranty.... All of the high-end brands offer a meager 1 year standard (except Wolf, which is 2 years). And 3rd party service contracts offered by the dealer are typically more expensive the higher the selling price the final cost of a high-end appliance is pretty steep indeed. And they don't seem to be any more reliable than the mainstream brands. So more points to the LG range with its standard 2 year warranty.
When I bought my high-end audio equipment at least I could justify spending $2200 for my Bryston B-60 amplifier because it came with a 20 year warranty.
