Regardless of your friend's intent it's likely not a good deal if it is over 5-7 years old, has a captured power cord or spring clip speaker wire connectors, uses a fan for cooling, or has a flimsy chassis and very lightweight.
Entertainer Stereo Amp?
I have a friend who's trying to sell me a amp that's branded as "Entertainer" model NA-2000. He wants a good amount of money for it but I have not been able to find even the smallest amount of information on the company or the model.It doesn't look like Audiogon even has any info on it. Anyone ever heard of this company? Is it any good?
