There are two inputs. One 1/8" jack on the front for ipod, etc, and two RCAs on the back for DAC, CD/DVD etc. Sound is very clear and detailed. Sound is not 'tubey' or slow. Very nice for desktop, nearfield use. Footprint is a little larger than a CD case so takes up very little room on your desktop...Unassembled tube dampers included as well as a 6ft chord to hook up to battery.
