Which one is the best INTEGRATED!!

Well, for more fun I'll mention Ypsilon and Absolare. I won't mention Kondo.

Dartzeel CTH-8550 as cited above. Have seen one or two used ones for sale in the 10-12k range. Built to outlive us all. 

I don't see how people can make recommendations based upon the info presented.  You don't know what Focal loudspeaker he has and the list of integrated span 30w to 300w.  Nor are any sonic preferences stated.  We also don't know where he is so we don't know what kind of manufacturer/distributor support is available.  Do any of the above posters really think they helped this person?

Based on the lack of information provided by the OP I think he probably has more information than he had originally however you bring up some very good points. I guess the same could be said for all the guys that ask open ended questions with out all the facts we need.

Definitely add these:
