Op-amp Rolling Using Sparkos on Fosi V3 Mono

[Gregss]

oh yeah IC's are more reliable than discrete circuits in case of voltage rise and even thunder stroke , right?

Right and discrete components are immune to lighting and voltage spikes - NOT.
A decent power supply with spike protection takes care of that.

if you rise voltage slowly, which one you think will fry earlier, chip amp or discrete amp?
oh yeah "ic's with protection are inmune to thunder"

The discrete amp.

Now the IC industry for convince me that IC's are better than discrete circuits in audio, send me an "Analog"Devices (IC corporation lol) PDF hehehe
What would say chip manufacturer?
That they have less reliability than discrete audio circuits?
Try it better

Trust this? https://www.ti.com/lit/ds/symlink/opa2828.pdf
Oh yeah!
And price? This is one of the expensive ones.
Approx. $10

Roll baby, roll. More than you’ll ever need.

Attention deficiet problems? I replied to your post that said a discrete OA can handle higher voltage than IC by showing you an IC OA that can run with +/- 110V rails.
You keep blathering the same nonsense.

Sory guys, Ill stop feeding the troll.

Hello all,

This is my first post. I have been reading for years but finally joined today because of this thread.

I have spent a decent amount of time reading about this subject all over the internet and just finished this thread. There seems to be a lot of data in this thread to support that it's a total waste of time to change out op-amps. I am glad I found this thread before I went crazy doing it because dam near the entire internet would make you believe you must have these and literally pay as much for those op-amps as I paid for my amplifiers. Thank god I don't have to do that.

I do have one question though that I don't remember being answered here, so apologies if it was. I read that you can get a very nice improvement from "removing all unused op-amps from your amplifiers". Specifically, I am talking about the Fosi Audio ZA3 of which I have 2 of them.

Is this information accurate that it will improve the sound quality by removing the subwoofer op-amps and any others I am not using? I am currently using XLR inputs only so I wouldn't need anything RCA related. Has this subject been discussed or tested and a data finding published?

Thanks!

No, it's not accurate. At all.

Thank you for the quick response. I guess now I can go through a nice 100 hour "burn in" to get it to sound its best. (Ducks tomatoes).

Yes, you can turn around and around, twisting your tail metaphorically, or just enjoy the equipment. I find Fosi and Aiyima products to be pretty darn good right out of the box. Enjoy the gear!

100 hours is fine if you don't want musical sound and prefer a thin, veiled, soulless performance. But if you really want the music to make you grin from ear to ear, tap your feet uncontrollably, and drop a steamer in your boxers, you'll need at least three times that depending on the ambient temperature and the quality of your power conditioning (I'm assuming your cables are liquid-cooled of course).

As a defender of R2R DACs, even I must admit that OPA rolling is one of the biggest scams in the audiophile space. Those are not even actively altering the sound. They either work correctly, or they simply dont and add distortion. Like with digital cables.
You are already using a very good AMP with the Fosi V3 Mono for a ridiculous price. I always said and say again. AMPs are the least important factor for sound quality, as long as they can deliver up to 25 Watts of stable power without distortion or harmonic funkiness. Which these Fosi do and then some. Im willing to wager, that most people dont even use 10% of their AMPs true output capabilities. You simply cant, especially with neighbours and your family around. Why add OPAs that almost cost twice as much in a 2 + 2 config? Its absolute lunacy. You are defeating the entire appeal of the device.
