I am driving a pair of AR1's (built in 500W Sunfire powered subs) with appropriate rear and center speakers. How suitable is the SA-XR50 or 70? Does it compare well with the Marantz SR5400 OSE, Harmon Kardon AVR230, etc.? Would like to hear your opinions and experiences.
They're ok, but I suggest you listen to them first, they can be kinda bright. The XR45 was no match for 5400OSE, but around the same quality as Sony DB790 (=DA1000ES).
