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.

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.

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.
