Yes you can. Ideally your CD player will have a quality volume control, high output, and low out put impedance. Your interconnect should be short and have low capacitance. The McCormack amps are particularly good choice due to their rather high (for solid state) input impedance and IMHO it's punchy extended sonic signature. Choose a McCormack that is on the sensitive side. The cons include a varying impedance depending upon volume setting and the chance of diminished dynamics.
