Does Op-amp Rolling Work? [Video]

[solderdude]

Yes, rolling the op-amp can change the sound (sometimes for the better!) if it's compatible and works without oscillating.

It can only do so when it is an op-amp that is not suited for the job or is oscillating.
One can perceive a change in sound when changing (suitable) op-amps but this is not caused by the op-amp themselves but is caused by the whimsical nature of 'human perception'.

No

Anybody had any experience with the SX35B and SX22B op amp? I wonder how they stack up against the SX52B, what the improvements would be?

Please only reply if you have experience I am not here to argue the pros and cons of op amp rolling, thankyou.

 

[solderdude]

As this is highly subjective asking for experiences is pointless. Those that pay this kind of money are guaranteed to hear (always positive) changes.

You would have to try all 3 of them yourself to know what 'effects' they have on your device, in your setup, to your brain.
Happy swapping !

Why don't you ask this at another forum, instead of here at ASR? I think you know you're not going to get the feedback on the above you desire.

Members come here to avoid these types of posts.

Yeah, some big jumps in prices with these 3 too. I just wonder if that’s reflected in the over all end result. Unless I actually get a job doing this I think I while avoid this warren any further and give curiosity a slap across the cheek and a seat in the corner of the room.

Or.... you can simply enjoy the gear/sound you have now and stop worrying about op-amps.

These op-amps have good specs so are likely to not degrade the signal fidelity at all assuming they are used in suitable circuits.
Not recommended for devices that run on voltage rails below +/- 12V (nor above +/- 18V) and don't do rail-to-rail.
So not universally applicable to any circuit.

 

[Schlippwhip68]

To be honest, I enjoy how my system sounds now and don’t want to change a thing.

Op amp selection settled
Valve selection settled.
Pre amp settled
Power amp settled
Speakers settled
Cables settled
Dac settled
Streaming source settled.

Good.

This flat earth forum is hilarious. Maybe it's people with hearing loss. There is no question opamps can change the signature of the sound. The question is what type of measurements are being missed. Slew rates?

Any evidence for this claim?

No.

Educate us how slew rate of op-amps will/can matter in circuits with very little gain and virtually no load to speak of ?

There is no question opamps can change the signature of the sound.

There is no question the act of changing op-amps can change the perception of sound.

Don't feed the troll(s).

Indeed it sounds like a troll but as we are all having hearing loss we can only read on meters if he is trolling or not.
And sure enough...

Ah yes, the sceptics and those who insist on data and evidence are now the flat earthers. Nice projection you got going on there.

Ragebaiting and trolling won't work for long here, just as a warning.

Ah yes, that dude whose fans believe anything he says, but accuse ASR of being a cult.

Nice self introduction to the forum. Perhaps you should cool your jets a little, have a look around, read some of the sticky threads and so on.


In other words - read the room, then consider how you want to present yourself.

No? Dig out whatever is in your ears and get a hearing test

*yawn*

this video is from a couple years back but i think it's kind of relevant to the conversation.
