Sean,
In addition to what Tthomas had already mentioned, I am using my Stratos on a pair of Martin Logans whose impedance was listed at 4 Ohms nominal to 1 Ohm at 20 khz. I was using a Threshold Stasis S500 Series II amps before, my speakers sounds no where near what I am hearing now. I am very happy with them (Odyssey amps) also.
