Are you saying 2.5 on the amp volume control or 2.5 o'clock. Big difference. Especially for us not familiar with amp volume control. Basically, if you're not driving your amp into clipping, you're OK.
If bothered, you can always use fixed attenuator like the that available from Rothwell or Harrison Labs, or more flexible stepped attenuators available from EVS or Endler Audio.
Also, contact Unico to see what they recommend.
