Here is why you should choose us!

Avoid fakes and dupes!

The Internet is full of counterfeit op-amps, many of the NE5532, OPA2604 and MUSES02 are re-branded lower quality OP-AMPS and you never know what you buy!
But you can't escape their terrible sound performance: Your ears will notice immediately. Hundreds of hours of comparative listening tests and dozens of different devices made us choose the dual operational amplifier with the best characteristics in all conditions.

AudioPrometheus FLAME

- Solid, extended, whilst well-controlled bass range.
- Cryatal-clear mid-range with plenty of detail and spatiality.
- High-range extended well beyond audible, yet silky and never fatiguing or metallic.
- High-class macro and micro dynamics.

1:1 replacement of dual operational amplifiers in the preamplifying sections, typically NE5532.
The NE5532 chip was released 45 years ago, surely still a good performer, but surpassed under most aspects.
The latter benefits are also audible when the "Flame" chip is installed in DAC devices or CD players.
In sone cases, in particular when up-grading older CD players, an expert intervention maybe needed in order to install proper sockets, as the stock op-amps are soldered onto the PCB.
CD Players from the 90's live a new golden age, with unprecedented sound prerogatives, formerly concealed by operational amplifiers not up to par.
