More power for moderate listening levels?


Hi,

I can't seem to find good information regarding the effect of relatively high powered amps on low to moderate listening levels. I have a low powered class A amp that sounds wonderful at moderate volumes but not surprisingly shows signs of strain when cranked up. I am contemplating an upgrade that would bring much more power to solve this problem. However, since I don't play music really loud that often I'm wondering if the upgrade is really all that necessary. It would be worth it if the reserve power of the new amplifier improved sound quality at all levels.     

Thanks for your help,

Brian

Tekton makes some great speakers, very high efficiency, great sound, and their favorite amp is Pass. It would seem a match made in heaven.  

That sounds like a recommendation to change speakers to your fav.
To contradict Mr. Miller, you don’t buy speakers to match your amp. If you like your speakers (and I don’t have any familiarity with them), buy an amp that matches the speakers.

My mains are 85 dB sensitivity. I use tube mono blocks. When I started they had the popular EL34s, very sweet sounding but not enough power for the speakers at 50 watts in triode mode. I swapped the EL34s out and replaced them with KT150s doubling the power. In triode mode I now have 100 watts and can play almost anything at a reasonably loud volume. When I switch to ultra-linear it doubles the power again and you can hear an increase in volume as they switch in real-time. They’re 3 dB louder. Now at normal listening levels I have plenty of power in reserve for peaks and dynamics and if I want to go to 95 dB I still have enough power for peaks and dynamics. So yes, it is reserve power. Tubes burn the power that is needed based on how hard they are driven by the input signal. I'm absolutely sure someone will correct me if I am wrong, but I believe SS amps burn at full power all the time.


You have to pay attention to the damping factor and the impedance curve of your speakers. Once I had decided on my speakers, I carefully checked all the amp specs to see that I would match to the speakers properly. Then the listening began.


If you go about it bassackwards as Chucky says you’re in for trouble.
As opposed to choosing what is bad, I guess. Like tuberculosis.

Yeah, you named it. Now you will have it for the foreseeable future.

OP, many posters want you to buy what they have in speakers and amps. Sure that would be great.
It would be worth it if the reserve power of the new amplifier improved sound quality at all levels.
Yes, that is it. But if you are happy with your speakers as you seem to be, add more power. Same brand amp, different brand amp, what ever. Don't change your speakers, get more power. You'll be happy.
