Review on Nobsound Precision Passive Controller Preamplifier by Michael Norwood

My Klipsch ProMedia 2.1 THX computer speakers are over five years old and while I liked them, the volume control has always been jittery, especially lately. And now when I adjust the volume, the sound is muted on either one speaker or the other. I've found spots that work, but I can't play my audio all the time. Moving on, I'm "discovering" the tube tone I can't live without now, and while I had hoped my preamp would be my new volume control, I can't get the most out of it without cranking the volume up. This volume control was perfect, no scratches, no cracks and smooth volume control. That's great!
