I would need a lot more info as to your budget and what you are looking for in "high end" I ahve done many High end kitchens with Ikea cabinets and one in Miami Beach for friends that are wise with how they spend money. I have used Poggenpohl they are awesome but really I cannot advise the price for most clients . I think a lot of these are to impress someone else not because they are so much better .For me the cabinet choice is made after I figure out all my appliances since IMO they are the workhorses in a kitchen and the cabinets need to be good quality but I also do not spend money to impress anyone else. This pic shows my kitchen in Calagery I priced out Poggenpol for this exact same layout and high gloss cabinets it was 65K I did this whole kitchen including appliances for less than 30K that kitchen is still awesome 20 yrs later .
