11 months agoit’s not the tube amp, it’s the high efficiency speaker. With these speakers noise will be higher just like everything else. There’s nothing inherently noisier about a tube amplifier.
A power supply only has a “sound” if you are hearing hum. A phono preamp needs only a tiny amount of power to function and any power source with reasonable filtering will be fine. If you want to be a purist, set up your phono preamp to be powered by batteries.
