He's just saying that it will basically sound the same as any other decent DAC... People that hear differences typically aren't using any listening controls so hear what they expect to... For the most part...Ok, sometimes when you dont have to add something with value is better not to say anything
The OPA are not replaceable in any case. They are soldered.
lolJust because they are soldered you can't replace? This is so wrong.
I will correct that one: "You can replace if you have the skills." (my case).
But for now, I'll just change the LME one.
Edit: I'm already looking into OPA2209 or OPA2189 to change the OPA1612. They are poor in comparison.
Edit2: Pulled the leg for the OPA2209.
It's not like you can properly identify changes if any, by swapping in and out and listening again. Your auditory memory isn't that good ... no one's is.Oh boy! Today I found my old opamp Metal Can !!
Changing right away.
Edit: Listering... NOW I got sound stage! Metal Can DO wonders.
PS: Fun fact, the PCB weight just 52 grams.
Like I said. They are close enough to have no measurable difference in audio band. Difference is way lower than your hearing threshold. Of course I know 49720 is the one that's corresponding to 4562.LM4562 is 100% the same rebranded/renamed to LME49720 (NOT 49710).
