I received the LRS+ a few months ago for my bedroom/home theater system (for use with a sub) and assumed I would have to get a new amp. I was pleasantly surprised to find that my old Adcom 545II drives them so well that I don’t even know what I would be looking for in another amp.
I believe the Adcom is rated around 100 watts into 8 and 150 watts into 4 but it was sold as a high current amp.
