Okay, got the Leckerton in last night and I'm glad I had the UE custom demos to play with.
...
The Leckerton with ADA 4627 is more neutral and tighter, better for controlling the UE11.
 
I think the Leckerton is definitely a nice little unit. Built really well, looks better in person.
 
UERM/UE4 can seem a bit thin with bright tonality on the Leckerton, with the UE11 muddy on the mini^3.
 
Source can really be heard with Leckerton in these combos.

I've got a UERM demo right now.. and I absolutely LOVE it.  I find it very complimentary to the JH13Pro FP.  Been using the UERM demo with the UHA-6S MKII's (built-in) DAC & amp (AD4627 opamp), and I agree.. this little rig sounds wonderful.  As you stated, it's very transparent and neutral.

CEE.. I might be PM'ing you about getting a UERM.. sooner than later.

 

Anax- I edited my post!  DOH.  Last night I had the iPad set somehow to "Treble Boost" with the EQ and was feeding the Leckerton against my iPhone 4S feeding the mini^3 via LOD.  I checked iPad this morning because it just didn't sound right when I plugged things in today.  The Leckerton with UERM and the 4627 is really flat, clean, and great. Thanks!  To me, not lacking in anything tonally and more refined than the mini^3.  mini^3 is still fun and a great pairing with UERM/UE4 but we'll see in a while how I feel about it after living with the Leckerton.    The Leckerton is so good and clean that I can pick out that little edge/resonance in the treble, Anax.  It's noticeable but the only thing that keeps UERM from being "perfect" for me and my preferences. I'm really glad the pairing sounds so much better today!
 
Combo is Leckerton with the LOD from iPhone 4S to amp section. The 1st gen iPad to DAC section of Leck is a wee bit brighter. Need to live through the combos for a while.  On high gain (Nick did lower the gain), there is a tiny bit of hiss...when I can I will swap in the 4627 BRZ version (4627 ARZ is in the unit now) and see if that helps at all (by lowering noise floor). 
 
@Flysweep, awesome!  Yes, let me know if you want to talk about them.  And, when you have a chance...did you also try the Leckerton by using an LOD to the amp section?  Which source are you using? If you do, please let me know how much difference you hear. 

The Leckerton seems to be getting smoother in the treble and is better in High Gain mode.  I now have no issues with the treble and UERM.  The overall sound is smoother with seemingly better weight in the lower end with the mids a bit clearer in High Gain compared to Low Gain.  I suspect that some UERM impedance characteristics are noticeable at the Low Gain level Nick set mine at.


Need to find out what gain my amp was lowered to and also roll in the BRZ version of the ADA 4627 to see if hiss lowers in High Gain (non-existent in Low Gain).


I can see why you like this amp/opamp combo, @Anax.  Now that the Leckerton seems to be settling in, I'll see over time if I can take a little more treble bite in the mini^3 in exchange for the extra bit of air/liveliness.  Right now, I like them both for different reasons.     

dB can do computer audio and has balanced or something. S (R?) is just a better battery life version of the original.

?  both are DACs so can't both do computer audio?

that's a negative. one can only do Apple iDevice audio unfortunately. I tried.
