I have been driving a pair of similar size Axioms with an NAD 40w amp, and have no complaints. The amp wil provide very good volume levels, and solid bass. I leave my tone controls in the neutral, or off position, and can readily admit solid bass. This would be emphasised if you were to put the bass controls into the situation.
You mention current of the amp. Be aware that this is the maximum output of current for the amp. By stating it, they are describing a solid amplifier design, that is CAPABLE of delivering this. It will not deliver it at all times, into all loads, at all frequencies.
Your room is similar in size to mine as well, and room tuning may be required. You will need to adjust the speaker placement and listen. I am sure Ian has some general thoughts and distances, but you may need to start with them and tweak.
With decent purchases on the horizon, I hope the turntable is of equal, or better quality! The source is often the most neglected, and most important piece of a properly designed system.
