somsit: thanks for the additional info. again, there is no dp-70 or 70v, at least in the usa. if the one-box player is a dp-75v, then it has virtually the same oversampling circuity found in the dc-91. the dc-75v, thus, is superior sonicically to the dc-91. the dp-65 or 65v, on the other hand, is not the sonic equivelant of the dc-91, and certainly not the dp-75v. i hope this is understandable. good hunting. -kelly
