Since you are looking at Japanese integrated, do not leave out Esoteric. The 30w/ch pure class A F-03A or the 120w/ch class AB F-05 are both work of art. Cheaper than their Accuphase siblings and approx same pricing as Luxman in the US and Canada.
You can also look at the Grandioso series if funds are not an issue.
