Which is the stock opamp ?Thanks n yes i do have the A07 with the stock op amps. Already on the hunt for LM4562 but I'm not finding it anywhere online except Mouser.in & their shipping that costs thrice the amps themselves.

Super...just checked and it's in stock. Order placed. Thanks mate.
The my only advice to you is swap only if the opamp is currently mounted on an adaptor. Please do not attempt desoldering and soldering.

Yes sir, they are mounted on adapters,have also read that many have swapped them easily. No soldering /desoldering.
Find a way to check if the part is genuine, if there is one.

Now how would I do that brother ? Isn't buying it from a front like TANOTIS good enough to ensure its genuine.Couldnt find any literature wrt making out the fakes.
I use RS Components to source my opamps so I dont know about Tanotis.
Let us know how it sounds.

Sure thing, will do. Just checked the webstore you mentioned. They have 4 diff types of LM4562 chips & only one that can be ordered individually. How would you choose the right one then? ( Did you pick the 5 unit package PDIP ones) coz the others show up as surface mounted. Just curious as its confusing.

Adding to this confusion is the fact that the LM4562 that i ordered from TANOTIS is nowhere to be found on rscomponents website. Are there many different ones and how do we conclude which works best for the Aiyima ? ( Is trial and error the only way or there's a defined path to selecting these op amps).
You also seem to be doing a lot of electronic work as this website caters to bulk orders mostly.
Yes i work with pdips. Sometimes one buys the small lots if not available individually.
Its basically trial and error. Secondly a lot of stuff on RS is available in small lots or pairs or individually.

Should thankyou for suggesting the website as they seem to stock many such things that are locally unavailable.
