Please read up on this article, https://www.stereophile.com/features/335/index.html ARC Ref 6 SE is a fully-balanced, Class-A design with zero feedback 😊 |
Many if not all components have power supply sections with a large massive transformer usually off to one side. Especially true of preamps because designers like to keep these noisy parts away from the sensitive circuits handling the signal. Not so critical with stock factory feet but many audiophiles add springs or cones. With these its critically important to balance preamp so it doesn’t tip over. |
