I recently purchased an NAD C350 integrated amp, a pair of M22's, and an EP125 sub for use in my small apartment. I listen to all types of music (on CDs and DMX) and I have my TV sound running through this system as well (digital cable box). The NAD C350 has no sub out connection (2 channel only). My question is, since I can connect the sub either 1) with an RCA connect to the amp pre out or 2) with speaker wire to the sub and then to the speakers, would one method yield better sounding results than the other and are there any other advantages to using one method over the other? I'm mainly concerned with music listening. Thanks in advance for you advice.
