... have you own experience in some good replacement for LME49880 with the same or better sound result?
The chart above incorrectly lists the LME49710 as discontinued. It was 'brought back' with this product change notice as of 4/28/2016: https://media.digikey.com/pdf/PCNs/Texas Instruments/PCN20151204003A.pdf
The parts in this PCN were qualified on the 6" and the 8" lines, so they didn't have to become EOL when the 6" line went away.

Well, heck - thanks for the pointer! TI's website says the LME49710 has a 'LIFEBUY' status now, which is sorta sad IMHO. I've been designing this very nice amplifier into a device, and I'm not sure that the OPA1611, their suggested "invented at TI replacement" is not a step back.
Thanks for staying on top of things, and cheers!

I just wanted to order more LME49860 for my project (Bridged Buffered Opamp Amp - a journey), but now I saw that the price at Digikey had become $37 for each! It is still listed as active on TI's page, but obviously they don't really want to sell it anymore.
In searching for alternatives I found the LMP8672: LMP8672 Dual 40V Low Noise Precision Amplifiers | TI.com
I'm wondering if this is the same amplifier, just marketed differently? The specs look very similar, what do you think?

I have good experiences with using OPA211 in my low-noise applications. Whether it is a good fit for your exact application is a bit had to say. But I encourage you to try it out.
It was a beautiful amplifier, but there is really nothing equivalent anymore. The AD797 has similar noise characteristics, and also has extremely low distortion, but it is slightly finicky to stabilize.
The LME49720 / LM4562 has extremely low distortion, and is also pretty easy to stabilize, but it has a good bit more input voltage noise. However, I imagine that you could build a somewhat low gain, fast, but low noise front end amplifier and put the 4562 in the feedback loop and get something more suited to a MC cartridge. For MM, the noise of the LM4562 should be just fine.
The LT1028 and LT1115 also have noise characteristics that are similar to the 49990, so they should be examined as well. Best of luck!
Unfortunately, the LME49710 is EOL as of 12-31-2017. You have to buy the dual version now.
