Hello Dellboy,
I just happened to have purchased a Cambridge Audio Azur 851A on ebay (refurbished)
Besides a CD63SE, I am not too familiar with Marantz, but I can tell you that I am very happy with the Azur 851A
I like the look and it is solidly built.
120W into 8ohms and 200W into 4.
But it's not just about power.
It sounds just fine to me.
Don't ask me to explain it, as I'm not into superfluous descriptions (Detailed, exciting, insightful etc lol)
.
Comparing it to my Onkyo TX RZ800 (AV receiver). It sounds just as good, though lacking in power compared to the Onkyo (Tannoy Revolution XT 8F bi-amped from the Onkyo)
I have it on a 30 day return. so if I am not satisfied. Back it will go (8 days so far)
The manual looked a bit worn, but otherwise the amp was in perfect condition.
Worth a look.
