    Good afternoon, I was wondering if my AU 719 will handle 4 or 6 ohm speakers? It has been recapped and still has the original output transistors. I am considering Monitor Audio Silver RS 6 or RS 8 speakers. Any advice and suggestions are very much appreciated. Thank You

    It wont have any issues with 4 ohms speakers. I have tried using Elac 4 ohms speaker before.

    It's a difficult question to answer with absolute certainly. Nominal impedance is exactly that... 'nominal'. A speaker's impedance can dip lower than the nominal impedance, and depending upon how far it dips (and how it relates to phase angle) plays a key role. Speaker efficiency also comes into play - a less efficient speaker will result in your amp being driven harder to achieve a given volume level, so if you combine low efficiency with tricky impedance dips and phase angles, this could well present a problem.

    Unless you have measured or published speaker measurement data, it's hard to say for sure. Have either of those speakers been measured/reviewed by Stereophile? If so, it will include such measurements.
