Cool Is LM3875 better tham LM3876

Hi,

I intend to make a GainClone amp but LM3875 is not available. I have bought LM3876 instead. I read somewhere that LM 3876 sounds inferior to LM3875. Is this true?

Thanks in advance,
Goldy

what if the 3875 is nothing but 3876 permanently unmuted?

Your first post said no, your second yes.

It's only a resistor which is probably burnt away in LM3876.

I said: no, they aren't identical (not totally)
and yes, the only difference is certainly the mute circuit

but it may be more that a signel resistor

Gentlemen:

Please stop this crap and answer the original question.

Which one sounds better?

I'm guessing that they both sound about the same.

If one should sound better, it would be the 3875 (less components in the signal path)

I can agree with that statement.

I have both chips. I'll build two amplifiers. One with the LM3875 and one with the LM3876.
I'll listen for myself and then measure the performance and report back.
