Agree that this is likely a combination issue related to DSP, amplifier input sensitivity and volume expectations.
Which miniDSP product is this? SHD, DDRC-24, DDRC-88A? I am guessing DDRC-24 as that is probably the most common and most likely to have volume issues due to lower output voltage.
There is a lot of good information in this thread but there is also a lot of "noise".
DDRC-24 has an output voltage of 2V, this will be achieved when output level is at 0 dB. If output level ever goes above 0 dB DDRC-24 will clip. It does not matter how this 0 dB is reached, you can program +50 dB of boost from a combination of input gain, output gain, PEQs and Dirac and if you set the volume control to -50 dB the output will be at 0 dB and not clip. If you look at the miniDSP output levels you can see how close you are to 0 dB and clipping. If your output levels are below 0 dB your distortion problems are not caused by the miniDSP regardless of settings in the miniDSP.
+4 dBu input sensitivity setting on 705Ps corresponds to a voltage level of 1.23V. This means that that the DDRC-24 should be able to drive the 705Ps to full power at this input sensitivity setting. However the actual output voltage from the DDRC-24 will depend on the level of the recording, the processing in the DDRC-24 and the DDRC-24 volume level.
-10 dbV input sensitivity setting on 705Ps corresponds to a voltage level of 0.32V. In this case the DDRC-24 will almost certainly be able to drive the 705Ps to full power (and beyond in to clipping). This setting essentially offers +10 dB gain compared to the +4 dBu setting. Using this setting with the DDRC-24 is OK as long as you are not experiencing hiss (due to higher gain) and you understand that it is possible to clip the 705P amplifier if the miniDSP output level exceeds -16 dB.
I also assume that you have not adjusted any other settings in the 705Ps like input trim, PEQs, etc?
