Almost 50 years at Rotel has culminated in the 15 Series relatively new and was highly anticipated from 2009. The RSX-1550 arrived at my home in mid-2010. Admittedly, I'm a little behind on my review of the Rotel receiver and although this is an apology to the good people at Rotel for their patience, it speaks volumes about the product I've had it in my system for many, many months.
