Default LM3886 vs TDA7294

Has anyone compared these two chip amps?

Just from looking at the data sheets the clear winner is LM3886 ( lower THD, better slew rate -almost double- , simpler schematics ), but I've never build an amp with TDA7294 so I can't say anything about the sound.

If you like so call tube sound, then TDA7293/4

I liked the sound of tda7294 I build, however i didn't build a 3886.

I've build though it's cousin, LM1875 and I was impressed. I thought it was better than the tda. I've listened both on the same sistem so I could compare them quite acurate.

That would make most tube specifications too bad.... unlistenable !
You don't really mean that .......do you ?

I didn't meant to say anything bad about tube amps or any other topology ( they all have pros and cons - I'm actually planning to build a tube amp myself one day ); all I said is that LM3886 has better electrical characteristics ( and it's simpler to build an amp with )

best regards

Sounds like BJT vs MOSFET again.

I think my TDA's should now be set up as the LM vs TDA question has come up again. All components being the same type ( psu , caps and resistor etc ).

I didn't get it done so far due to various other issues. I have the 7293 and 7294 . But I guess it's better to try the 7293 first.
Cheers.

The chips from ST are quite often used in low end car stereos and in computer speakers. The LM3886 beats the crap out of them.
