25W highest possible or RMS
Is the 25W measure of voltage the highest possible for the amp+ or the actual RMS voltage?

HiFiBerry team This is the maximum output power over a long period of time. Neither the concepts of peak power nor RMS power really fit here.

pl Yes but it is necessary to know if it is
1 x 25 W or 2 x 25 W
and 25 W on 8 or 4 ohms
and 25 W RMS or ... just a exotic value ?
thanks for your answer -
pubdc Yes would be great to learn the power specs to understand which speakers can be driven. -

Hi Stefan,
the power rating of the speakers is practically useless. It only tells you, what maximum power the speaker can accept without being destroyed. However you will notice this just by listening.
Basically you can use ANY 4-8 Ohm rated speaker with the Amp+. This won’t damage the Amp.
You should select the speakers not by power rating, but listen to different speakers and choose the pair that sounds best for you.
The power output is about 45W peak power into 4 Ohm at 18V. At lower voltages and higher loudspeaker impedances it is less.
At 18V, we recommend a power supply of at least 3A (or about 60W).
Best regards
Daniel
