Ok, maybe I was generalizing a bit.... Sometimes it's marketing, and sometimes there's something else going on. Some designers just push the 0.001% distortion for marketing reasons, but others get there for the right reasons. If you get there by designing amps with huge open loop gains, so that you can apply a ton of feedback, you're designing for marketing reasons. If you work hard at designing a circuit that has very low open loop distortion, and apply a small amount of feedback for stability, then you're designing for sonic reasons. And I agree that the second amp design will sound better. My point is that the numbers alone give you an incomplete picture, and are often misleading. -- DCtoDaylight Audiophile wish list: Zero Distortion, Infinite Signal to Noise Ratio, and a Bandwidth from DC to Daylight ------------------------------------------------------------------------ DCtoDaylight's Profile: http://forums.slimdevices.com/member.php?userid=7284 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
