Printed sharpness is suspect as well. Usually, Ti stuff is sharply printed that I've worked with anyway.
Same for BB chips (and salsa).

The 5532 looks legit, proper date coding and pin 1 marking applied, unlike the OPA 1656 you showed earlier.The included NE5532P sounds great to me at 39.95 price tag. Still waiting on the Digikey components to arrive.
2024 September MalaysiaWell here we go now. These are the pics of the Op Amps from Digikey. OP1656. Sorry, A little tougher to see because I did not want to take them out of the protective plastic until I decided I had the nerve to try and solder them in. The ones on the left are the ones from Digikey. On the right the ones from Ali. Wonder who is lying...
I have a Chan's Audio AD 1865R R2R w/JM5532 opamps to sometime swap into my system for comparison. I'll be curious...@Sunnbobb after looking at the pictures of the OPA 1656 that "adeleparts2010" has for sale on ebay they appear to be an exact match for the OPA 1656 that I bought from Ali E. They look nothing at all like the ones from Digikey. I think they sound just fine though. Who knows.... Image one ebay. Image two Ali E. Image three Digikey.
I wonder about the "Bar" marking on the left of the chip as opposed to the "Dot" adjacent to Pin 1. All the Ti and BB chip I have (Mouser and Digikey) have the dot.@Sunnbobb after looking at the pictures of the OPA 1656 that "adeleparts2010" has for sale on ebay they appear to be an exact match for the OPA 1656 that I bought from Ali E.

The dot is official, not the bar. TI has a spec for where the pin 1 marking needs to occur and that bar does not conform.I wonder about the "Bar" marking on the left of the chip as opposed to the "Dot" adjacent to Pin 1. All the Ti and BB chip I have (Mouser and Digikey) have the dot.
And the ones we use are silver plated, I never knew that.Jesus! Look at the tech drawing of that thing!
