I own a Pass Labs X250 and it runs HOT and adds to the electrical bill every month but sounds fantastic. I also own a BHK 250 which also sounds wonderful. The next thing you should consider is what happens if you have a problem after the sale or your warranty has just expired. These two companies are still owned the founders of the original company. And in my experience are offering a service second to noe.
