STOP! I've owned the 3.6s. I'm only going to tell you this once. Buy an Sim Audio Moon W-5. I've owned and tried MANY amps and the W-5 is THE amp for the Maggies. I could go on and on, but a 100 watt tube amp (like the ARC VT-100 and the Power 2, both of which I've owned), will not provide the current to produce the bass you will want.
If cash is not an option, use the tube amp on the mids/highs and use a high current SS amp on the bass in a bi-amping configuration. That would be the best bar none.
