In your opinion, which would be the best op-amp for metal/rock music Jenneth? |

yeah, i am curious as well
Alydon;5244129 said:I don't know much about linear power supplies, but I think one would produce a more "natural" output waveform at least in theory, correct?
what do you mean by "natural" output waveform in case of a direct current?
Alydon;5244129 said:However, switching PWS's of sufficiently high quality have good enough shielding and cap filtering to drop EMI/RFI down to <10-20mV at the molex, which is pretty impressive. And isn't hum an issue with linear PWS's?
Agree, its not that bad in comparision to ATX specification (120mV for 12V and 50mV for 5V) however its still far from perfect. According to silentpcreview.com (Seasonic S12II-380 Power Supply | silentpcreview.com) Seasonic S12II-380's ripple for 12v rail @ 90W = 16mV and increases to 26 mV at full load, for 5V its 13 and increases to 15).
Taking into consideration power requirement of the card (20W) [thanks ROBSCIX] I believe that powering the card from independent, dedicated, well designed SMPS should allow about 2mV ripple, which seems to be significant improvement.
