Default Sound quality: LM4780 vs LM3886

Hi all,
I did search for an answer on this, but all i got was millions of unrelated threads.

Simple question.... which one sounds better?
LM4780 or the LM3886?

Thanks.

Hi,

How about building both then use each for R & L channels?
I think listening to this kind of set up would be revelatory!

I have built the tda7294 & tda1514 and I want to try 3886.

Take a look on this site: http://www.elmatrd.ro/amplificatoare.html

If you want to experiment with chip amplifiers, the romanian company seem to have some good offers. For example the 2x40W kit is just 9$.

1 million Romanian money = 30$

And what about the 1 x 100 W kit with 2N3442 for just 9$. Incredibly cheap! Did anyone try this stuff?

This reminds me of some stuff I saw in Indonesia, usually the pcb quality / soldering is poor, and no-name or even fake components are used.

That's not simple...

I have built plenty of chip amps but I can't say which one is better than which. For every single chip there are many possible implementations and setups.

But I dare to say that LM1875 is sheet. Golden eared fellows should be able to disqualify this cheap from the other chips mentioned above

In my implementation of LM4780 and LM3886, I enjoyed the LM4780 a lot more.

Well it seems it doesnt really matter now.

I cant find a good source for LM4780's in Australia, so it looks like the LM3886 will be it.

Eeek, 16 * LM3886T's is going to hurt the wallet

You could check if there are some left

That 100W amp is just 4.80! OK it looks really cheap, but the design looks pretty good (certainly could have made it less parts). Would be great for a sub amp. Wonder how much shipping to England is...

The LM3886 and LM4780 use the same silicon die, LMP3886AT. There are two of them in the LM4780. They should therefore sound almost identical.

I've done a fair bit of technical research into the LM4780, see my web page at http://home.pacific.net.au/~gnb/audio/lm4780.html

Cheers, Glenn.
