Pls. contact me if I have ordered the wrong item.  I noticed a "stereo" version of this same unit in the listing but could not find any information in the "pull down",  It was blank.  I have an Allen 301, MOS 1.  I think I have ordered the correct item.  If, I have made an mistake or the stereo unit is a better choice, please contact me.  Thanks and regards,  JIM
