Linear Power supplies for DACs...?
Is there real SQ benefits or is it placebo snake oil?
i have a Chord Qutest and it has a wall wart. Lots of people say there’s real benefit to adding an external LPS.
Plenty of choices ranging from $50 - $500.
Sure, a home audition is ideal.
but, what do you guys think?
Not just for the Qutest, but in general for DACs.

LINEAR POWER SUPPLIES CAUSE HUM Anyway I wasn't referring to only LPS or power supply in general but any noise in the signal that can get to the speakers. Power supply or transformer hum is harder to get rid of short of replacing the offending item or getting rid of the component. |
djones51 No, not really. Hum in a system could have several causes: - DC offset In the three residences, I’ve lived in the past 20 years, hum has been completely eliminated each time depending on the cause. None of the cures included replacing any equipment at all. I’ve never had a LPS that caused a hum whatsoever. Each LPS significantly improved the SQ. They generated clean power. |
I've lived in 8 residences in the last 20 years and never had or heard any hum. I've never noticed it with wall warts or linear in amps. This thread is about DACs and if a linear would improve or is it placebo so whether you use linear, switched that came with the DAC it doesn't really matter since we don't listen to those wires anyway their waveforms are filtered by the DAC. |
