I agree. I use a predecessor of this product, it was sold as a kit once.  
I don't know if the algorithm has been improved in the meantime, but my 
box works really good. The depth of noise reduction is adjustable with a 
pot and it does not reduce the loudness of the signal but only the noise. 
At the highest NR setting voices start to sound "spacey". I normally use a 
medium setting for best S/N effect. 
The noise reduction is only noticeable wih weak noisy signals. There is 
nearly no effect on S9+20 signals without noise.
My box has one disadvantage, I don't know if this has been changed with 
the new product, there is only one channel, so the sub receiver has no NR.
You might need two of them. ($$)
