The specs listed are for the Phono Record Box E, which in addition to being a phonostage also serves for analog to digital (A/D) conversion of LPs. The Phono Box is a phonostage only and thus less expensive $60, and yes, if its gain is also 40db it will boost the signal over your Behringer by 5dB. This would not bring the volume up to that of your CD player however might be enough to satisfy your needs. The voltage supplied by the Phono Box would be about 1.7X that of the Behringer. I believe Needle Doctor sells the Phono Box, they are good to talk to. Look them up online.
