Hey Greg,
When I saw that you had a passive preamp for sale that you built, I thought that was very cool, but what the heck is a "passive preamp?" Turning to the ChatGPT "robot," I found the following description:
"A passive preamp, also known as passive volume control or passive attenuator, is a device used in audio systems to control the audio signal's volume without actively amplifying or modifying the signal. Unlike active preamps, which include active electronic components like transistors or operational amplifiers, passive preamps use passive components such as resistors, potentiometers, and transformers.
The primary function of a passive preamp is to provide impedance matching and volume control between audio source components (such as CD players, turntables, or media players) and power amplifiers. It allows the user to adjust the volume level of the audio signal before it reaches the power amplifier.
Passive preamps are often favored by audio enthusiasts who value simplicity and a purist approach to audio reproduction. They can provide a transparent and uncolored signal path, preserving the integrity of the original audio signal."
This is new to me, have others had experience with a passive pre?
Congrats on the build Greg, and good luck with the sale!
