Nominal Impedence and Amp Taps

thanks for the help so far, my amps are Sonic Frontiers Power 3's and the speakers are Duntech Black Knights (Dunleavy). The amps came to me in 8 ohm mode, but until today I didnt want to mess with them, today they went into 4 ohm mode. Ive tube swapped 3 days ago, so I cant tell what the differences Im hearing are from.

Hi Justlisten Duntech may be able to give some advise when you mention the name of your amps. I have a Anthem amp1 that has 4,8, and 16ohm settings. My spkrs are Meadowlark Kestrals that are 8ohm. When I tried the 4ohm tap the spkrs didn't sound right at all. I also called Meadowlark and they told me the 8ohm tap would be the best. Also since you put new tubes in your probably won't have a clue untill the tubes settle down. Best of luck

My amp has 2,4, and 8 ohm taps and my speakers are N802's which are rated at 8 ohms but I've heard that they can dip down to around 3 ohms in the bass. The amp manufacturer, VAC, suggests trying the different taps to hear which works best. I tried all the combinations including running the bass at the lower ohm taps and the treble at 8 ohms whilst using the bi-wire configuration. I obtained the best sound from the 8 ohm tap and single wired to the speaker.
