gain control issue


I have a unico hybrid amp. [80watts] driving celius 202 speakers in small room 11'w13'd by 9'h. I can only turn the volume up to 2.5 on the dial then it is a bit loud. Am I loosing anything by having a lack of control re volume, if so is there a solution?

The sources are Unico cd player and rega 25 tt. The lack of gain control is the same for each source. The gain control dial goes up to a max of 10 stops. I am checking out some attenuators. Thanks for the input.
Ahh, I get it, sorry. I thought you didn't have enough gain, was thinking 2:30 o'clock on the dial. As suggested, I'd call Unico or Kevin Deal at upscale and see if they had a solution.
Thanx, Russ
