Rogue Tempest or Jolida JD1000A Integrateds?

You need to take a close look at your power requirments.
Confirm the dB sensitivity on you Cloffhangers.They are in the Low 80dB's I belive. You need lots of juice to get these going.I would suggest with either amp a 90+dB is required to get optimum results.

Natalie, The Cliffhanger's I have are 88db.

The Rogue Magnum Tempest has double the power supply capacitance of the reular version along with larger and better output transformers. It ought to drive the Cliffhangers very well providing you room isn't huge.
