I have bought the three MiniDSP modules - MiniDSP, MiniDIGI and MiniAMP, and I'm right now testing the MiniDSP with 2 way crossover. It's replacing my Behringer DCX2496.
The noise is considerable lower than the Behringer, and dynamics are better. A rather thick curtain have dissapeared. Next move is to try the MiniDIGI and then MiniAMP in 4 channel mode, and then 2 channel mode with my NXP based class D amps.
An externally hosted image should be here but it was not working when we last tested it.

Hi Kjeldsen
What PSU are you using there?
Inevitable question: what does this current setup cost?

The PSU is from Mean Well 24 volt 3,2 amp single supply. You can use any supply with 12-24 volt larger than 65 watts. MiniDSP reccomends 24 volts 65 watts (2,7 amp).
You find the prices at MiniDSP.com, but each module cost no more that 99$. There are discounts for bundled packages like mine. The PSU is 35 us$ excl VAT and freight. I bought it in Denmark.

In Denmark the Behringer DCX2496 is 435$ incl VAT compared to the 350$ incl VAT I have given for 3 MiniDSP modules and a SMPS. Add another 50$ for a case, cables and connectors. All in all not much cheaper, but you get a 4 channel bridgeable amp and full spdif in/out. In other words more work to get it up and running, but a bit cheaper, better sounding and more flexibel.
MiniDSP also have really good customer support.

At the moment, the X-over features are very basic compared to the Behringer. The Behringer wins on x-over features, but lack in sound quality and noise as well as size if that matters.
Uhh... I thought the latest software made it more flexible (fixed roll-off rates vs additional PEQ per channel, for instance).
The software more flexible now, but there are no shelving on the PEQ's and only a few x-over topologies with fixed slopes. The Beheinger is very flexible on these issues.
Have just tried the MiniDIGI module with a lot of distortion. You realley have to dig into I2S to understand what to do. I think I have two I2S master MCLK, so I have to "slave" one of them, when I get home from work.
The software is very easy, but stacking the boards and get the configuration you need, are quite hard work, and require some reading and understanding I2S routing.

This is interesting.
I'm considering this DSP for my car-audio set up (4-Way active set up)
Let's wait for your comments 🙂

I just had a jumper-setting in the wrong position. With spdif input the boards are almost silent. So you DIY'ers who make high efficiency loudspeaker should take a look on these nice DSP kits. I can hardly wait to get the MiniAMP up and running. I guess any background hiss, will disappear.
The sound quality is very good. One thing to piont out here, is that I don't have a high end system. The days where I had the time for that isn't there anymore, so I can't tell you if the DSP crossover have high end capabilities. But, you have the option for full digital in/out via both I2S and spdif, and that combined with high end DAC's or digitally moduled PWM amps, should be very interesting.

The MinDSP support guy hinted that the constraint lies with the present interfaces, and that they are looking at high end DAC/ADC interfaces.
Thanks for the info Kjeldsen!
Most interested in this Mini DSP Unit. 🙂
Please give as much information as possible about how it functions when you've become used to it. I'm strongly considering purchasing it and pairing it with the Dayton DTA-100 when it becomes available again!
Perhaps you could test it on a friends set of high-end speakers? they would likely be interested in looking at your new toy as well!
And Shaun? Why would the DAC effect the performance of the Mini DSP?😕 Wouldn't the DAC be dependent upon whomever is using it, and whatever soundcard they are running? (or Serato, Tractor, etc) The Mini DSP would simply be accepting this signal and applying various processing (crossovers, phase, time alignment, etc) before amplification. Am I missing something here?

Kjeldsen,
I am interested in your experience with the miniAMP and noise/hiss. I'm looking for low noise processor/amp for compression drivers.

No, you are correct. The MiniDSP itself is not the constraint, and is said to be running full 24 bit. But the ADC is not of the highest spec. See this post from which I quote the following:
I'm glad to see my little project is helpfull. I have just got the last components to my project. I have two young kids taking a lot of my time, so don't expect everything to be up and running in no time ;-). I will do my best to have a test cabinet with all three modules working by the end of next week.
