Before I purchased a Luxman 507uX MKII I also looked into the comparable Hegel model. Look at the pictures of the interior wiring of the Hegel 390 at
https://www.hegel.com/products/integrated/h390 (right above the technical specs) versus what you see after you you click on the picture of the interior wiring of the Luxman 507uX MKII (right above their Specs section) at
http://www.luxman.com/product/detail.php?id=4. Draw your own conclusions.
That Hegel hides where their integrated is made is telling as well. The Hegel 390 gets great reviews, but again you’re gambling on Chinese products durability. I thought about Japanese Accuphase integrateds too, but there were local availability and pricing issues if I recall. Sounds like some other good choices have been mentioned above. Again good luck with whatever you choose.
