Is this a real TDA1541A?

This raises an intresting question: Is the single/double crowns THAT much better? I mean good enough to justify around or well over USD100?

Its almost like buying a myth

When I built a TDA1541A DAC, I put two chips in parallel. Paralleling several chip is an old tried and tested technique for reducing inconsistencies by averaging out the measurements across the chips and flattening (making more consistent) the response. Having a double crown eliminates the need to do this, as the double crown has no notable inconsistencies. It is for those that want the top 1% of measured chips and to to eek out every last bit of consistency across the spectrum from this chip and related designs.

I'm trying to design a dac with 4xTDA1541A, fed by normal/inverted signal.
The intention is a 2+2 (balanced + parallell) TDA1541A dac.

Strange, are they fakes?

By now one should suspect any S2. I would not buy these.

Two things that make me suspicious:
- lasering instead of white printing;
- datecode 0449 (didn't Philips stop making these ~1996?).
