Thanks for your inputs, Larry. Have you tried plugging your Sigma11 to the DACMini anyway?

The funny thing is that it's less "correct" from the engineering standpoint, but as is often with the arts, "precision" may not be the same as "pleasurable".
That seems like a rather ambiguous description of the difference especially when you consider, at least from how I understand it, that the higher output impedance may have a different effect depending on the phones used. It could have little to no effect with some or it could sound a bit better or possibly worse with others. Now something I couldn't get a handle on was how significant the difference between 1 and 10 ohms would be so, ambiguity aside, the difference may very well be slight.
I could be wrong on this so others more knowledgeable than I please correct me if necessary, at least from what I understand, due to their design the LCD-2's shouldn't be affected much, if at all, by a higher output impedance. My concern lies more with IEM's which typically can have low and widely varying impedance curves that would be more affected by the higher output impedance. After owning but having had to sell JH Audio 13Pro's due to fit problems and issues caused by TMJ, I know my Triple.Fi's aren't the last word in IEM's so I'll eventually be on the hunt for a universal that gets me closer to the performance of the 13Pro's, it's this search and not knowing where it will take me that influenced my desire for the output impedance to have as little influence on the sound as possible. Maybe in this case I was being overly cautious but not having a whole lot of knowledge on the subject I felt it was the safer route for me.

I'd want to verify my 15v S11 has the correct polarity first.

Should be fine if the specifications in the Centrance site is correct.
My DACmini arrived today. Packaging seems very well done and the build quality of the DACmini itself is outstanding. During the waiting period I started to wonder if I'd made the right choice, especially with all the initial positive feedback on the Lyr paired with the LCD-2's, although I've only had a short time to listen so far it seems those fears were unjustified. I started out listening to the LCD-2's and the combo put a smile on my face but I was curious how my Triple.Fi's would fare so I switched over to them and haven't been able to take them out, the DACmini is breathing new life into this old favorite.
So far I've only got one rather minor gripe, it seems the PSU comes with the plug to the DACmini attached but no power cord to go from the PSU to the wall. I assume this is standard because I bought a second PSU to take into work and it didn't come with one either. Not a big deal for me, I have a couple decent power cords and some standard issue ones floating about but thought it worth mentioning for those that might not have a spare one lying about.
Wow... you used your Triple.fi's with it! I can hardly turn the volume up past 8 1/2 on the attenuator with my GR07's, even with my RE-262's. How low do you have the volume without channel inbalance..??
They dont ship power cords with the DACmini due to so many differences with Country power outlets. I got a piece of paper in mine that stated this. No biggy as i had a spare cord put away.
Ahhh yes, that makes sense.
Yeah, there's not a whole lot of usable volume, I was at about the same on the dial, between 8 and 8 1/2 but the channel imbalance is at an extremely low volume so there's enough in between there for it to be usable.
I had borrowed a friends Headroom Desktop Portable amp when I was looking at changing my system around and I found it was fairly reasonable to lug back and forth to work in my backpack so when I realized the DACmini had similar dimensions that became a big part of my decision to buy one. If the DACmini stays the plan is to use it both at home with the LCD-2's and at work with IEM's.

Or you can just sell off your other gear...
I see you own the Gilmore Lite, how does the mini fare against that?
Well, if you help me out and you swear that the polarity of the DACmini and HDP PSU is the same I'll try the Sigma 11 with the DACmini soon. I'm just too tired to look it up right now (pretty sad).
