I have done a fair bit (somewhere between lots and nuts) of looking at 30" ranges of late. I've settled on the BlueStar, which doesn�t quite fit your model � standard layout has 2x22k burners, 1x15k burner, and 1 x simmer burner. You can re-arrange these for a very small up-charge; and I reckon they�ll build you a range with a different mix of burners as well. But my understanding is that the 22k burners, even on low, are not great for really low output simmering. Hence, if you really want all four burners to "go to 11," as it were (22k btu), this might not be your first choice. If it's a deal-breaker, then it is. I ruled out Viking early. First, I'm upgrading from a GE Profile that's a dozen years old or so. Moving to 4 sealed burners with a max output of 15k is not what I want � I can get more power from the new GE ranges. Second, I have concerns about reliability. I know a couple of folks personally (not just virtually) who have had problems with Viking, and CR reports a relatively high failure rate for the brand (I know that CR gets a lot of flack on this board for a variety of reasons, and I regard them as a mixed bag � OTOH, I don't think for an instant that they cook their numbers and when they report double the failure rate based on a decent sized survey sample, or "n," that's a concern for me). Wolf offers the same output, better reliability numbers from CR, and better consumer satisfaction numbers from JD Power. Thermador was a fall-back choice for me and my preference among the sealed burner options � I liked the size, shape, and elevation of the star burners, which go to about 18k btu (plenty for most applications). Plus I've cooked on one and have some friends nearby who've had good luck with theirs � tiny little samples, arbitrarily chosen, but the personal reports and hands-on exposure count for me. The CC range mentioned above may most closely fit your criteria. It's likely well worth a serious look if you can check one out in person. My own decision to focus on BlueStar has nothing to do with any particular defects with the Capital. An up-close examination of the ergonomics matters to me. I really like the way BlueStar uses the limited space of the 30" top, for one thing � a very key thing, for me personally � and the operation of the new racks in the oven seems very solid and smooth. For another, I tend to prefer models that have been out in the market � and subject to minor fixes and tweaks � for a few years. For another, I've got a colleague who has been using the 36" version of the range for 4 years or so, as well as a friend of a good friend, who grew up in the restaurant business and has several years' experience with the 30" BS (and a willingness to converse and provide very, very detailed reports). Tiny, arbitrary samples, but when systematic evidence is terrible or entirely absent, I give a fair bit of weight to face-to-face conversation with folks I know. Of course these are all reasons for me that might not apply to your search at all. And as I said at the top, the BS range in standard configuration just does not meet your criterion of having all four burners go from super low to super high. It's not an issue for me, but I understand the drive to optimize flexibility on a relatively small top, with only 4 burners (personally, I�m going to augment the range with a small, portable induction burner that can be pulled out as needed to, e.g., keep stock on simmer off to the side, or keep a back-up pot of water near boiling, but out of the way when I need that, and put away when I don�t). But this is going to be your range, and there�s no point in going to the trouble, and spending the money, if you are not going to get what you want.

Scratchin' my head over why both previous posters added an "e" to these companies' names. You'll be better able to search this forum and the internet in general for information about these companies if you spell them correctly, Thermador and Dacor. You should note that the Bluestar ranges have open burners, not sealed like the Dacor and Thermador. Many people on this forum are fervent proponents of open burners. Which goes against general popular view that sealed burners are preferred. You should do research to decide whether you would like open burners; there've been a couple of threads on this forum about the pros and cons. Thermador seems to be panned a lot on this forum. At the simmer level the Thermador burners click which is annoying. Dacors get very mixed reviews. Some love them, some have had a lot of problems. What kind of exhaust will you have for these high-powered ranges? Make sure your ductwork is enough for a high-btu range.

I'd look at other brands - Wolf, DCS, Capital, Bluestar although the last 2 have only all-gas ranges.

Thermador is extremeley reliable. I had a Thermador 36" electric coil cooktop for 18 years, 4 burners and griddle in the middle, not one problem, still works, but we did a big house reno including the kitchen, so went with new appliances. I now have the Thermador built in oven, very good unit, largest capacity out there too. It is pure convection, pure convention or combo of the two. The only small negative I have is the spacings of bars on the oven racks themselves are a bit wide, only time I notice it is if I do a large batch of banana loaves and instead of doing 2 large loaves, I make 6 mini loaves. Then you have to space the mini loaf pans exactly right so they dont keel a bit. I went with a Viking 6 burner induction cooktop. I had a Dacor built in oven previously, same type of model, either pure convection, pure convention or a combo, worked great, but had a few issues at the end, ie: sensor went (they dont have thermometers) and was fairly expensive to replace. Also, Dacor does not seem to keep parts in supply for as long. If I kept it much longer and would need parts, some would not be available. My friend has a Thermador star burner gas cooktop, she likes it a lot and has no problem with simmering. I would buy Thermador again in the blink of an eye, they are extremely reliable from my experience.
