Best linear Audio amplifier for physics projects

[jfdo]

Hi all,

There are many versions of amplifiers, Class A, Class AB, ...Class D, Class G and so on. I wonder whether anyone of you have experience or can recommend a good linear stereo amplifier IC or circuit (with out of about 10-15W) to amply signals/waveforms from Analog Discovery output?

Thank you.

You might have a look at the low end of the frequency range, especially if your application is sensitive to group delay variations.

DC-coupled, even more difficult.
