A DSS receiver needs a minimum signal level of about -65dBm to operate properly, and a signal to noise ratio of about 8dB. Unlike analog signals, a digital signal that is below the threshold input level of a receiver can sometimes be recovered through amplification. I have seen signals that had dropped to about -75dBm recovered that way, though you may not have the same luck in an MDU since the signal may have gone through more stages of amplification and picked up more 3rd order intermodulation distortion than did the signal that I saw recovered in a technical seminar at WSNet's headquarters back in 1997.
I believe a Sonora D575 amplifies the evens but not the odds. The logistical problem you face is that the D575 does not pass power to the amplifier. so to add an inexpensive, inline amplifier to your drop you will either have to put it between the destacker and the receiver or you will have to use a power inserter and possibly a voltage blocking coupler on the other side.
Can someone from your MDU operating company do a signal level check in your unit? A properly designed MDU distribution system should develop a wallplate level of about 55dBm. Sonora engineers really severe reverse tilt into their commercial line extender amplifiers, and because of that, it is actually more common for a Sonora system to lose transponders at the low end of the spectrum (1, 3, 5) as the signal becomes weak than it is to lose them at the upper end (30, 32).
