Cocktail Audio N15 - A Contender?

@rowbuzz, bondmanp    good timing for me  on this post.   I'm working on what I want to use in order to upgrade system a bit.   Always just used   my Mac Book is  the storage and running via usb to my Burson DA160   (no volume control---but if I recall the early units were not highest highest bit rate or something to that effect .
     I don't want to store music on my older Mac anymore as lost a lot  a few months back when Mac crashed.  Its recoverable as a lot was burned from CD's (ALAC) and a lot of music from BandCAmp so able to download as many times as I want being I paid already.  I imagine  most sites work that way?   The wobbly volume control is a negative.   Could it be a manufacturing defect?    While the price of these is not terribly high I would think quality of parts could be higher considering 900 is not cheap.   ,   
I don't need volume control so will check out Lumin D2 and any more info would be appreciated.   So heres what I need and any ideas on other units would help.    onboard storage,  internet radio ,  no volume control and don't really need a DAC-  My sense is and outboard DAC is going to be better than the DAC in a unit at this price point.   Hard to find as most all seem to combine DAC, volume control, preamp, , etc.  
  
    

not sure how off topic?  Im looking for a combo unit that streams as well ,, A DAC is not needed really and as long as there is digital out then don't have to use or compare the on board DAC with the Metrium or other.    My sense of the  industry is to get more business by selling all in 1 units so as to increase potential for sales esp for those who don't want to "bother" with separates.   Its most often about introducing "advances" in components to maximize sales .   Thats my take anyway.   

@bondmanp     thanks,   don't think I checked the Melco out yet..   Was considering the Vault2 as well,  will have to recheck as forgot why I dropped it from my list..   multitasking here.
