Hi and thanks for the additional information.
I still have a miniAmbio box I bought a couple years ago, but I found the ADC/DAC converters too coarse for entry into my systems signal path.
I replaced the old miniDSP units I am using for sub and super-tweeter control with the new miniDSP 2x4 HD unit - and I thought that was a big upgrade for sound quality. So I think it would be a fantastic thing if someone can port the RACE stuff to the new miniDSP 2x4 HD, which would offer more processing power, better ADDA, and direct digital input which can eliminate the AD step.
Or better yet, some box which would offer hi-res digital input and output.
I need travel for work the next few weeks, but will try some of the other RACE plugins and programs as soon as I return. My system is in a dedicated small treated room, music only, with a pretty good computer-based front end (listed in my HeadFi profile), so I am pretty confident I can get this to work one way or another..
Thanks again...

You can always port in ambiophonics to your MiniDSP the DSP is available for $10/- from the MiniDSP site.
I will forward your suggestion to the DSP4you management. I too think the Ambiophonics plugin should go into the 2x4 HD unit and told them that almost a year ago. But I guess the demand is not there yet.
I have never noticed any coarseness with the analog miniDSP and they have sold hundreds of them. It operates at 96/24 so I don't see why there should be a problem. But I agree a digital input and output for that matter would be nice. I use only digital amplifiers from TACT and NuForce so I am normally 100% digital up to the speaker leads. But I use miniDSPs for demonstrations, 3D movies, etc. and have had no problems.
Hi and thanks again for the additional comments.
I removed the barrier and set the speakers at 20 (10/10) degrees and tested Amtra again (exported processed files in the default settings and used in my normal setup) and found some artifacts with pop music type productions (classical was better but not as clear as without the processing). However, I immediately noticed some of the possible benefits of the speakers in this configuration, so will keep the speakers set at 20 degrees until I return from the business trip.
I did a quick check at miniDSP for the software and iirc they specifically mention it will not work with the HD version miniDSP... I do not know how difficult to do this port, but with the proliferation of desktop speaker setups currently being used, I would think there is some marketability in a higher range product than the current. I admit that my initial observation of grainy-ness with the standard miniDSP may have been partly or wholly attributable to some cognitive bias on my part (my DAC is a well-fed Audio-GD NOS7).
Anyway - I am currently building a second input to my preamp for casual listening. This will be a SoTM SMS-200 to some yet-undecided DAC but with a new computer. I will build his computer with the idea to be able to run either Samplitude or JRiver with an Ambio VST plugin. I already have all the software, and some of the computer parts, so hopefully in a month or so I will be able to do a proper test.
For anyone interested in this stuff, I have just learned of some software seeming aimed mostly at pro-level use (meaning probably very expensive).. but nonetheless interesting in that this company also found the concept worth developing into a professional level product.

It does. The plugin is available for 2 x 4.
