Summary: I purchased the Azur 651R to go with my Polk RTI A7s. Out of the box, this is a very solid unit, build quality looks very clean. Connection and setup was fairly straight forward and it was fairly easy to switch between HDMI passthrough and upscaling.
Pros: Solid construction, good looking receiver. Decent sound/video.
Cons: Not quite enough power to really open up my speakers.
Summary: Had a bad start. went through scratch and dent . First two receiver`s was junk sent back. 3rd one was a charm. New. I have had it for two month`s,and pushed it several times. I`m replacing some old carver and sunfire stuff for space, less cable`s and good fiber optic sound.
Pros: Nice power. Every thing work`s like it`s supposed to!
Cons: Time spent dealing with the not so much repaired scratch and dent.
Summary: This was an honest purchase for me. What I mean is that I thought real hard about exactly what i needed and wanted my next receiver to do. I needed a receiver that performed great at what was important to me with no useless "bells and whistles".
Pros: Robust all metal, heavy construction ( almost 40lbs!). Powerful high current amp, a clever cooling system, and features that seems to be tailored just for me. This is a no nonsense, all business machine.
Summary: Longtime owner of Yamaha 7.1 120w per channel. Not really sure anymore of what it did well. The Cambridge OWNS the living room. It literally keeps all 7.2 speakers tight,crisp and present as needed. Never gets muddy and just stays smooth, even the rear surrounds are alive.
Pros: Very very strong amp that doesn't lose it's precision as you increase wattage. Handles digital beautifully.
Cons: Slight con that the Audessy mic kept setting sub crossover at 40hz, easy to adjust up to 60 or 80hz - still refining.
Summary: I'm on my second unit therefore t he 4 star rating vs 5. The first unit lost audio output not 5 mins into use. Crutchfield Tech Support and I worked for a hour and determined finally a defective unit that was returned.
Pros: Top of the line sound reproduction! The Japanese can't touch it!
