4 or 8 ohm with Harbeth

Chashas1,
My amp is a Rogue Audio Tempest bought from a dealer that does not carry Harbeth. My thought in posting this question is to get input from those directly familiar with Harbeth and tube amps with 4 and 8 ohm taps. BTW all my current system- amp, cd player, speakers, turntable, phono preamp, and subwoofer has been purchased from dealers.

On some ARC amps, the feedback is taken from the 4ohm tap. I find it sounds the best. When a speaker manufacturer says their speakers' impedance is 8 ohms understand that this is not a constant across the frequency response of the speaker. An 8 ohm speaker can dip to 4 or 5 ohms at it's minimum. This usually occurs after it's resonance peak and is a function of the crossover and how each driver is compensated. It's easy enough to try both taps and see which one you prefer. This should not cause any damage to speaker or amplifier.

Hi Valinar,

Could you post your impressions of the Rogue Tempest?
It seems to me also that you had Dynaudio C1s before the Harbeths, I'd be curious as to why you switched.

St. Louis Stereo in downtown St. Louis, MO carries Harbeth plus Leben and Audio Research tube amps and could answer your question. On other posts people have said to just use the output that sounds better to you!

I have Special 25s myself and at some point want a new amplifier.
