I have owned a system that consisted of a pioneer p99rs...esotar 2 components and was blessed with a brax amp. All supposed to be top of the line. the very top....none of it mattered without a correct install and tune. It actually taught me that the latter 2 were the most important so I sold all of that equipment and am now shopping for off the shelf parts. The morels are on my radar and would love to hear feedback.
