Go for the amp whose sound you like the best and still has sufficient power. Herman is right about erring on the high side. Al has given you good advice also. Just remember that because 2 amps have the same power rating does not mean that they will sound the same. Try as many amps as you can, you will be surprised at the differences.
How is the power range determined?
Let's say that you have a floor standing speaker with the freq. resp. 30-20KHz, 8 ohm impedance, and 90dB sensitivity.
How would you (or the manufacturer) determine the power range of the speaker?
Is there a way to determine the optimum amp power for the speaker?
If the speaker manufacturer states the power range as 50~300 Watts, if price and size don't matter and everything else equals, would you rather go for as much power as possible, or would you still try different amps with different wattage to determine which amp would be best for the speakers in your room?
