Difference in sound, LM3886, LM3875

despotic931 · 20th June 2008, 03:43 PM

I'm just mainly curious if one chip sounds better than the other. I know that the 3886 will have a bit more power, and I know that the 3875 has better s/n. However I have never heard an amp built with either of these chips. Could those of you that have share your opinions please?

I have built both. To my ears the 3886 is the more analytical chip and perhaps a bit coarser than the 3875. 3875 is slightly mellower.

Not a huge difference but i also prefer the 3875. Less mechanical, more magic.

how about bass sounds at 3886 n 3875?

thx

I would probably say that the 3886 Bass is a little drier and less full than the 3875.

3875 gets my vote too...

Alright, well that settles it then! Is it true the 3875 is being discontinued?

My vote for LM3875.

Yes, but only the LM3875T, the non-isolated version. The TF version still has "Full production" status. But remember that there still is the LM3876 which is a LM3875 with the mute option/pin (and thus slightly different internals).

I'll be honest, I will be building from a kit as my skill level isn't quite there to build from scratch yet (ok, maybe it's my confidence level that needs improving). Anyways, I haven't seen a kit with a 3876, are there any other differences between the 3875 and the 3876? Also isn't the "TF" the better version of the chip anyways?
