Op Amp Rolling

[NTTY]

12 years ago I tested some op-amps I had lying around in a C'Moy (including rail splitter)

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Very interesting! Thank you for sharing

I'm very glad to have discovered that page with all that software on it.
I can already see how much fun I'm gonna have with that harmonics VST lol.

That Audient (it's the older model from 4-5 years back) has 1-line level input.
Here is a picture of said input:

Can't wait to nerd out with DeltaWave and Multitone.
Thanks @pkane for making such software available for us poor audio techs.

However, we did not get any measurements with and without the op amp.

Hey @Bartez2000 still planned for 2025. I've been overseas due to a family bereavement, 2024 was a crazy year.

You didn't really think @quocheiser already had measurements, did you? That was an EQ to compensate for "veils lifted".

@quocheiser:
IF there were a significant difference that would be a strong hint for bad things (like oscillations) going on.

Btw, the sardonic tone on this forum surely puts off lots of people who are here to educate themselves and also enjoy the hobby.
I must have let this "veils lifted" comment slide as I tend to turn the other cheek, but now you're just putting words in my mouth which is really uncool.

An addendum to this thread that I posted rather on the Fosi Community forum that sums up why I won't be bothering to measure differences in op-amps in my system https://community.fosiaudio.com/threads/op-amp-roll-zd3-or-za3.5450/post-6133

Thanks to everyone kind or helpful when responding to my original post in this thread. I've saved a lot of time and energy due to your knowledge.

Ah yes, the Sparkos SS3602 ended up being my preferred op amp in my VTV Purify Stereo amp with VTV I/O buffer board after trying several different op amps. BTW, those I tried included the Burson V6 Vivid which I found a tad warm and slightly lacking in detail.

Did you try the Sparkos 2590?, just curious

No, only the SS3602. But I note the VTV I/O I used will accommodate the "professional" form op amps.
