More Power is always good?


Hi all,

I'm a little lost in my search for the amp. Does more power (like more than 100W) means good?

I have been around listening to various amps, maybe a little too much that confused me.

Say for a room of 16ft by 20ft. What is the optimum power requirement?

For example, once I heard the Sugden A21Se (Class A 30W) driving the Spendor S6E, everything was nice except that I found that the basss definition and extension is lacking which is a concern to me, the showroom was smaller than my room. That's why I'm looking for amp with more power (like 100W), am I wrong? Will Class A amp like Sugden MasterClass or Accuphase E530 or Lavardin or others similar amp with power rating of 30W-50W be sufficient?

by the way I am using the old SF Grand Piano Home. I'm looking for a good amp that will outlast the GP Home, i.e. I don't have to change amp when i change the GP Home.

Any comments?

Thank you.

Bass quality can easily be compromised due to lack of power. This is where a low powered amp will show clipping first. It's best to have an amp that has enough power that it nearly never or never clips. I've seen a number of times where what you describe was no more than a lack of power. At normal listening levels you only use a couple watts or so but when a strong bass line comes in that's when your amp can go into clipping and it's easily audible. The power draw during these periods can need 100 times the power of your average listening needs from your amp. I use a 300wpc amp in my 12x17 room with 90db sensitive speakers and feels it's adequate. With A 100wpc amp I'd be clipping for sure.

When you double the output power you only gain 3db which is a bit more than noticeable. So you'd probably want to go to at least 100wpc if you're struggling with 30.

Almost all the time a good SS amp will have better bass than a tube amp. The damping factor of tube amps is typically very low in comparison and it's quite audible.
Eljif makes the right point. It's the dynamics that need alot of power and once you listen through having adequate power you'll never go back.
