Honestly so far, I see no reason to not get the BRZ unless you want to pinch pennies.  In which case why bother w/ a portable amp if that's your priority.

They aren't taking PayPal for the UHA760 preorder as he can't charge until he ships the device. Talk to him via email/offline and he might relax the rules for a custom amp.


Edit: Enough of us bugged Nick that he added the BRZ as a $14 option :)

I currently have the regular 4627 on my UHA-6s MK II. Is it worth the extra money to purchase the 4627-1B?

If you can wait a week or two, I can have a better answer for you.  Just too much on my plate atm.

Yep, no rush. My money can wait.

Will be interested to read your impressions of both.  I generally like the Herus very much, but with a couple of minor reservations.  If the Leck works with iOS devices and can run with the big little dogs, I'm interested.

I just placed the leck order today. I'll post some thoughts here and over at HF when I receive it.

First thoughts trying out the new Leckerton 760:
The ODAC is smoother/warmer, more natural than Leck 760 DAC using USB from old Mac G5 Tower. 
760 DAC section suffers some grain, digititus from my computer with UERM (with your iems, may vary). 
Didn't compare 760 DAC to the 6S DAC, but both DAC sections don't grab me to keep listening.

But: the Leck 760 amp Gain and digital pot is silent even in High Gain with the AD 4627 BRZ opamp until about 1pm on the pot (well past my listening range).  That's great because the UERM sound better (bit more full and better tonal balance) at higher gain settings and the 760 is better suited to all kinds of phones with different sensitivities and not requiring physical gain adjustment modifications from Nick. 

My 6S MkII with AD 4627 ARZ version opamps and at High gain has hiss and not a very usable range of volume with channel imbalance at low levels. I have to ask Nick to change my 6S now to -6db (-12 db and the low gain was too low at times, and stock the low gain is a little high for UERM at times).  Plus I need to put the BRZ version of the AD 4627 opamps in and then compare 6S to 760.

The 760 digital pot and 3-position gain switch are really nice. Quickly turning the pot can produce the <slightest> switching noise as the physical pot signals digital volume control. (Ratcheting up the gain?)  Not a problem for me, what I don't like are the noisy iBasso volume pots.

My plan is to continue to use the iPhone w/LOD or the ODAC to amp section and after proper head-to-head (adjustments to 6S mentioned above), decide which to keep.

Crossfeed puts more in center and pulls from the sides.  I probably won't use but it might be one of those things you have to use for a while before you like it?

Note: I'm just putting it through what I will use it for (UERM).
