I do have the Bhi NEIM 1031, which I dont think they do anymore and it is certainly a worthwhile addition to the 6500 and 7610 that I have.  Guessing the new parametric DSP would also be.  Did see them demo'd at Dayton this year

I have the EQ20B-DSP connected to my legacy 7851. I should connect it to the 6400 and give a report. It works really well on the 7851 with both devices set simultaneously to provide only a small amount of NR. I have shocking suburban QRM here, which is not helped by using an OCF!

David, please post your report.
I contacted BHI a month ago and asked if they would provide a schematic or at least point of connection to Line OUT.
As far as I know (i could be wrong), most people use powered Speakers on their computers and having EQ20B-DSP with only powered output make it challening setup.
Currently I use headphones and Powered Speakers. BHI response was to use Headphone output for speakers or headphone. For the price they charge I do not need another box where i constantly switch output. I do not need their Powered output and in case they can provide point where I can get Line Out from, I defently would order right away. Month ago I was told they will check with Engineer, but he is on vacation... still waiting for reply.

Sergey,
Mine should arrive today. Plan to first try Bose Companion speakers(powered). If there is a issue I will try my Yaesu 9000. I will post initial results on how the speaker connections went. I am sure there will be a learning curve on using the box.

Jim,

Just make sure to use headphones output for powered speakers input.
Maybe you can do recording?.

The unit arrived and I hooked it up.
Sergey YOU ARE CORRECT YOU CANNOT USE POWERED SPEAKERS!!!
I first tried using my Bose companion speakers. No joy. Had a faint hum was all that was going through.

I then rewired and hooked the unit to my Yaesu 9000. It works perfectly. 
First thoughts: The DSP works very well.

I had the NR OFF on the 6700 

Below is a photo showing the unit infant of the Maestro for size comparrison.
David Livingston let us know when you get your unit and what you find.

I do not notice a DSP lag
Sergey I will have to play with the equalizer a bit more to give you an honest option. The DSP works great though.

Thank you Jim, i agree with Sergey statement below, can you make 2 audio files: with Flex NR only and with BHI dsp for comparing purpose

Thanks Jim.
So, do you prefer BHI dsp for noise reduction vs. Flex NR?

I got reply from BHI. They now understand the importance of Line Out. They are going to build a prototype and test it, but it will not happen before October
