It's all about sensitivity and headroom. If your speakers make 90db with one watt. Then they will use one watt no mater if you have a 50 watt or 500 watts amp connected to them . The only difference is you paid a lot for those extra 499 watts that your not using. You need headroom for the loud spikes especially in classical music but 15db should be more than enough. So to get that headroom you need your amp will need to deliver 16watts. Quality watts are expensive. Doubling an amps power often means a doubling any of its problems plus a quadrupling of the price. If you don't need them then it's better to go with a lower powered amp with higher quality watts.
What does moving from a 150 watt amp to a 400 watt amp get you?
Hi all, I’m coming back to tap the knowledge of the forum again. I have a pair of revel ultima studio 2s that I very much enjoy. I’m currently running them with an Ayre V-5xe. I’ve seen others say that these speakers need to be driven by 400 Watts to get them to sound their best. I sort of understand the relationship between wattage and sound volume, but if I am not looking for “louder” what do I get with a more powerful amp? I don’t hear clipping. More current? But what does that do? Sorry for my ignorance!
