Do any amps have 6 ohm taps for 6 ohm impedance?

I'm a newbie, and I don't understand how impedance works. I've just bought a pair of Hyperion 938 speakers that the Hyperion website lists as having a 6 ohms impedance with 3.8 ohms minimum. I'm traveling right now, but I'm pretty sure my amp has 4 ohms taps and 8 ohms taps, maybe even 16 ohms. I'm planning on buying a new solid state amp to drive these speakers, but am I likely to find an amp with 6 ohms taps? Do they exist? And if I don't find one, can I drive these speakers using the 8 ohms taps?

Thanks any help anyone can offer. I know this is a truly ignorant question.
