Can all outputs on the XSP1 be used?
For instance. Could you use the balanced and single ended main outputs As well as the single ended and summed subwoofer out?
Main balanced out - directly to Airmotiv 6s
Main single ended out - headphone amp
Subwoofer single ended out - headphone amp
Subwoofer summed - subwoofer
Now, I understand the XSP is not “intended” to work this way, but would it work? I was told possible load issues, but surely someone here on the forum has attempted this with either good or poor results.
The main balanced and single ended would never be used at the same time.
The subwoofer single ended out and summed would also never be used at the same time.
Basically I need a balanced out for my speakers and 2 sets of single ended for my headphone amps. The subwoofer summed is a simple bonus if it can be used for a sub as well. Hopefully this makes sense. I know it’s a non traditional setup.

The XSP-1 can drive four amps. Two balanced and 2 unbalanced connections. Put both toggle switches to FULL. I'm not sure but I think the Subwoofer summed will not work in FULL. If you switch away from FULL to LOW PASS then the Subwoofer outputs should all work.
Page 12 of the Users/Owners manual
12. Full Range / Low Pass Selector (for Subwoofer Outputs)
To make the Subwoofer Outputs of the XSP-1 full range (and disable bass management for the
Subwoofer Outputs), set this switch to the right (away from the Low Pass adjustment screw).
Setting this switch to the left (towards the adjustment screw) enables bass management for
the Subwoofer Outputs. When bass management is enabled, the Subwoofer Outputs carry only
the low frequency part of the audio spectrum (the crossover point is set using the Low Pass
adjustment (11)).
The Subwoofer Summed Output provides a signal that is a sum of the Left and Right Subwoofer
Outputs, and is appropriate for use with a single subwoofer. Some subwoofers include internal
(and non-defeatable) bass management, and so work best with a full range signal for their input.
When the HT Bypass (Home Theater Bypass) mode is enabled, all three of the Subwoofer Outputs
carry buffered copies of the signal received at the Home Theater Sub Input (the signal is reduced
by 3 dB on the Left and Right Outputs).
Note: To set the XSP-1 for “full bass management”, set both switches towards the center
(towards each other).
Note: The High Pass and Low Pass crossover points are typically set to the same frequency
for smoothest blending of high and low frequency bands, but this may not be optimum in all
systems

In certain combinations, certain outputs may stop if you actually short circuit others, and connecting something that has a really low input impedance to one set of outputs may reduce the signal level on other outputs, but you can absolutely use them all at once with no problem under normal conditions. (I've never tried that particular combination but it should woprk just fine.) However, note that, if you connect two different amplifiers at the same time, you won't have separate Volume control for each, and they may end up playing at very different levels (unless the amps have their own Volume controls).

Thanks for clearing that up.
The balanced main output and summed sub will play simultaneously.
The single ended main output and single ended sub output would play simultaneously.
Those two listening situations will never cross paths. It’s either the headphone amps on and speakers off or vice versa.
And yes, the Vallahallas do have their own volume control. So it sounds like everything will work just fine.

Side note I was told by one of Emo representatives that this would probably not work. Just an FYI

Well, let’s hope it does work, just bought David’s used Gen1
