Which amplifier is good

[Kamranbits]

tpa 3116 vs STK 4231

Both are 100w
My usage is for aiwa bookshelf speakers

I believe the original Sanyo STK 4231 is discontinued and is not recommended for 4 ohm loads like your Kenwood/Awai speakers.

That leaves you with the Class D choice which is 4 ohm capable: 2 × 50 W into a 4 Ω BTL load at 21 V (TPA3116D2).

Thanks for info,By the way they claim many things the manufacturer that it has DSP it will correct the sound as per distence ect ect is it true
And what really does DSP do
Is it works like Dolby which can customise sound as per needs

If you are asking if the TPA3116 has DSP built in, then the answer is no.

Digital Signal Processing (DSP) can allow you to adjust the EQ, i.e., amplify or lower the level of certain frequencies.

The amp shown in the image above includes volume, bass and treble controls, but not DSP.

DSP can also be used for room correction, i.e., to make sure that the sound is optimised for the size and shape of your room.

It is written on a amplifier built in DSP it uses tpa3116 chip there is no control for such EQ then how can I adjust certain frequencys ?

With the meagre amount of information you have given me, I have absolutely no idea!

From the link, it looks like the DSP is automatically applied and there is no user control. Alternatively, the DSP labelling could be marketing hype!

I've never used one of these devices, but presumably the amplifier package will come with instructions should you choose to buy it.
