I agree, also to understand if it is a placebo effect or real

not only placebo..but better or not etc..
No
Hello! For me, after replacing the opa (1611), the pro plus does the following: if I turn it on with the amplifier turned on, after the boot time (45 sec), the speaker pops quite loudly. The problem is that I don't know if he did this before or not...can someone tell me if he does something similar? Anyway, it sounds nice, the sound is definitely better with the 1611 opa.
Please, can someone tell me whether in its factory state, when you start the Pro Plus with the amplifier turned on, is there a pop in the sound after the boot process (about 45 seconds) or not? It annoys me, because I didn't listen to it before the Opa exchange 
anyway, the sound is really great. I was still thinking about whether one of the capacitors should be replaced or some other simple tuning.

If you didn't listen to it before changing the Op Amp how do you know it sounds better now?Please, can someone tell me whether in its factory state, when you start the Pro Plus with the amplifier turned on, is there a pop in the sound after the boot process (about 45 seconds) or not?

Of course I listened. it is clear that it was worth the exchange. (I listen on an ACR ISOSTATIC RP-400 MK2 speaker). I'm only interested in the boot pop, I didn't notice that... I definitely recommend the replacement to everyone, the sound is clearer, more defined, airier, the bass is even more controlled. Now it sounds like it is perfectly on par with my 1000 Euros AKM dacom.
