What 2.8 Ohm load speaker specifically?
If the load varies widely by frequency around a 2.8 ohm average spec, then I'm thinking any tube amp, even the Atmasphere, may not be ideal.
I'm thinking one of the other Class A SS recommendations, assuming they double output from 8 into 4 and 2 ohms, or the Rowland or Bel Canto Class Ds that do same would be better.
