I can second that. With no antenna connected I can hear some spurs on the lower bands, mainly 160 meters and a little on the other low bands, but with the antenna connected, band noise covers them up completely.
The only complaint I have heard about the MFJ-4125 is that, while it is electrically quiet, acoustical noise is another matter. The internal fan is rather noisy. I designed a proportional fan controller to slow the fan down under normal operation and speed it back up again if the supply gets hot (say for continuous-duty RTTY operation). The article was in February 2010 QST.
