McIntosh MX132, MX121, MX122 aren't that good for two-channel listening to music. You will have to step up to its top of line HT preamp processor such as the MX160, MX151, MX150 to achieve great quality stereo listening to music to match with your MC602 amp. Since you aren't doing HT if I were you I would get a good quality stereo preamp. McIntosh makes good stereo preamp.
