I agree. The MFJ is hard to beat. I haven't tried that SCAF filter but since 
it's only a "low pass" filter you will still hear the thumps and rumble of 
the LF noise.

For a great all-purpose audio filter, the MFJ-784B tunable DSP filter is 
hard to beat. This one can be tuned for very narrow (down to 30 Hz) 
bandwidths, which can be centered around your favorite CW offset (pitch) 
frequency.  It has ten memories.  I have five each CW filter bandwidths 
saved for 550 and 600 Hz offsets, respectively. I use it with my Omni 
VI/Opt. 1.  It can also be used for SSB and data signals, and it has a 
variable noise reduction feature as well.  Since the filters are FIR (finite 
impulse response) there is no phase distortion.

The drawback is that it costs more than the SCAF filter.  It's worth 
considering.
