I've seen a number of people say that when Luxman was acquired by Alpine, the brand rather quickly slipped in quality and design. But then, weren't the well respected R-11x series receivers made after the acquisition? Alpine apparently held onto the brand up until the early 2000's, so it was a good long 15 years of ownership. I'm just wondering if there was a certain period where Alpine had not yet contaminated the brand too much. I understand the acquisition took place in 1984, so certainly anything released in the mid 1980's had probably been on the drawing board before then. What models or years of Luxman/Alpine gear should be avoided?
