I may purchase an NAD 2400 stereo amplifier for $400.00 Canadian with NO TAX to use for external amplification with a Marantz SR 6200 receiver. What sort of sound quality does this puppy have? Its 100 watts x2 into 8 ohms. Its pretty old and used, but its specs were pretty good for its day and even now. Any experience with this amplifier? Is it worth it? Should I pay another $300.00 for an NAD C270? It'll cost me almost twice as much.
