Recommended amplification

Power and listening level are tricky. A 3dB increase in listening level is often referred to as a just noticeable difference...but it requires 2x the power. A 10dB difference in listening level is subjectively twice as loud...ye requires 10x the power. And then we come to peak to RMS levels. With non-compressed material a peak to RMS level of 10-15 dB is often found - which requires transient power 10-30x the average level. So the peak requirements at higher listening levels can quickly escalate.

I don’t think you need 200 watts for the 3a Signatures in that size room.  But I think those speakers like more power than 10 watts. I have them and they sound better to me with more power - particularly with high current amps.  The bass is more controlled and everything gets a little more detailed.  They’re great speakers and you van get more out of them with a better amp.

Thanks for all your input.  I appreciate it.

Question to those who say more power equals better sound:  Could the differences you heard going from a low wattage to a high wattage amp just be atributed to the different manufacturers voicing their gear differently (assuming the increased power wasn't from the same company)?  Has anyone gone from a 25 watt Pass to a 150 watt Pass from the same era?  Or any other company that produces a broad range of the same power amps with the only difference being their wattage?
