Does a passive preamp with transformers so that its impedence can be matched with an amplifier have the potential to provide better sonics than a line preamp? I have a Simaudio Celeste preamp and a Harman Kardon Citation 7.1 amplifier. Lynne
Thanks. That's what I thought. The 7.1 has an input impedence of 22k and the Celeste has an output impedence of 120 ohms. I have no idea how synergistic or unsynergistic that is. Lynne
Lynne, the "rule" is 1 to 10 (line stage output impedance to amp input impedance, so you should be okay.
I cannot stand the lack of dynamics on passive volume controls and suspect that is the mismatching of the source output impedance through the passive volume control to the amp input impedance. But it really doesn't matter as five attempts was enough, I am sticking with quality active line stages.
I disagree with all the passive preamp folks. Saying things like, "It will be quieter," is not always true. My Fire preamp is black background as any passive, arguably more.
