James,
No one can really tell you how a specific piece of gear will sound to you in your system, or how dependable it will be. All you can do is get a diverse set of opinions.
Audiogon has a bluebook which will tell you, for a fee, what equipment has sold for on Audiogon.
You can search the forums and reviews for opinions on gear. I'm sure the AMR 77 has been discussed and those discussions may be useful in deciding if you want to give it a try. Listening to it in your system is really the only way to be sure whether it's right for you or not though.
