Is there such a thing as too much power?


   I downgraded power from 300 watts per ch to 70 and I like the sound better! I always thought more power is a good thing, but could that be wrong?

Please enlighten me...

The 6B4G is a 2A3 with a different base.

A minor point, but for the record it's probably worth noting that the 6B4G is a 6A3 with a different base.  Both of those tubes, in turn, are electrically similar to the 2A3 except for their filament voltages and currents, which are very different (6.3 volts/1 amp in the case of the 6B4G and 6A3; 2.5 volts/2.5 amps in the case of the 2A3).

Simple fact is that if you can get a more powerful amp to sound as good as a lower powered amp through the entire spectrum more power is better. Problem is that many higher powered amps dont sound as good as their lowered powered alternatives. This seems especially true of S.S. amplifiers. Part of this must be an issue of circuit complexity.

What irritates me more than speaker efficiency is the issue of low impedance speakers. To me there is no reason for the existence of low impedance speakers!

"High current amps are what is needed, not necessarily high wattage amps, unless you’re pushing high efficiency horn loaded speakers, or something like them, although they usually go hand in hand."


I agree, while recently researching class D amps I asked PS Audio about the output current of their M700's Here is the reply....

"The M700's run 350 w at 8Ω and 700 w at 4 Ω. Of course there are times it will peak above this but this is a general continuous wattage. I hope that helps. Please let me know if you have any other questions."


I explained that I knew the power rating, I wanted to know the current and received this response.....

"I did not have this Spec so I went to the Designer of the amp and this is his reply.

“it’s not a good idea to look at the power In terms of amps. It really needs to be considered in watts to understand the m700s capabilities.”



I found that interesting since I had read the output current of other brands of amplifiers. Not sure what to make of the lack of response.
