Mostly likely the 8 ohm would be best. With most tube amps the actual impedance is rather unstable, one reason most people like solid state units. As for safe, hard to tell without knowing the make and model of speakers being used.
amplifier impedance
Hello,
I recently bought some speakers that are rated at 8 ohms but drop down to 6.5 ohms. I have a tube amp that has separate 4 and 8 ohm taps. Most of the advice I've gotten is try both taps and see which one sounds better. Would one be more optimal than the other, or more "safe" for the amp or speakers?
