Default Tda 2003 sound quality.Show me your opinion!

Well,i have a tda2003 amp and im very happy with it,probably the best chip amp ever,i like the sound.
Its a class b amp but there is no distorion at all.What i dont like is the clipping sounds very bad.
Its much better than tda8560 or lm1875T,which are my other amps.
Now please tell me,what experiences have with tda 2003.
Here is my amp,i dosent look very good since i dont spen much time designing the looks,it is also powered by an 12v 250ma old cell phne charger which is ok for 2 ohms but only at low-ish volumes

It is my favourite chip amp. Great sound is due to current feedback topology which is rare in chip amps. It is designed for car radio and for battery supply. If you use it with 8 ohm speakers it will deliver only about 5W and will clip badly if you push it hard. If you like it's sound as much as I do, I suggest you to try TDA2005 which is the same amp but in bridge mode. You won't need output cap for it. It offers twice as much power as TDA2003. But in any case you should use some kind of regulated supply and avoid supplies of over 12V.

I have it too, i think its one of the best single supply car amplifiers.

I ran mine in mono with 8R speakers, sounded wonderful.
Po
= 0.05 to4.5W RL
= 4Ω

Love it

I still think 1875 sounds better.

Thanks guys,my lm1875t was my first amp and it sounded like **** because i messed up the grounding,and no one wanted to help me,so i got angry and threw them out,but now,im broke and i cant afford them,sholuld have kept them,also the same for tda2050,the worked 10 secs,an power surge came in and blew the up,since i have 25v transformer and they have a maximum of 25v supply
