In Reply to: the output impedance of a CAT ultimate preamp and the input impedance of the Pass X350.5 amp posted by jfrago_52@yahoo.com on December 29, 2004 at 23:48:36:
In general, a PRE should have the lowest output impedance practical for the circuit.An AMP should have the highest input impedance, ditto. This svoids the AMP loading the PRE signal.
Impedance matching is only relevant for POWER transfer (not voltage) in tube amplifiers, or for tramsmission lines at high frequency to avoid signal reflections.
