They are rated 4 ohm, though they really don't fall beneath 4 ohms much and supposedly stay around 5 ohms for much of the frequency range.
4 ohm tap sounds more forceful, but not as enjoyable overall and the top end seems to get a little darker overall.

Jason.......As you can see from the impedance and phase measurements from the Stereophile magazine review of the Guarneri Evolution, the speaker never dips below 4 ohms. In fact the speaker only touches 4 ohms at 4500 Hz. The majority of the frequency range sees the impedance well above 8 ohms. This may be why you are preferring the 8 ohm taps on the PrimaLuna Dialogue HD. None the less, after you have a couple hundred hours on the Evo's and the amp you may want to revisit the 4 ohm taps just to see what you think.
