Yes, SV-2A3 has volume control(only one set of input), but the quality of the control is unacceptable to me. I changed with dual mono ladder attenuator, and work very well. Adsal is right. Uno is very sensitive. Cary's amp is quiter than the SV-2A3. SV-2A3 uses AC heater, Cary 300BSEI uses DC, but I like SV-2A3 better.
