ProtoDAC TDA1387 X8 project

Wow, I must say, for the price of a Pi3B+ and a ProtoDAC, this is definitely the best value out there.

I ran a comparison between the ProtoDAC (with linear Power Supply) and my current setup, Allo DigiOne --> SPDIF --> Arcam iRDAC (with linear Power Supplies).

I am in no way saying the protoDAC is not awesome, but I did hear some discrepancies between the 2 systems (I've probably tried a dozen other systems before choosing on the Allo / Arcam solution). Here is my opinion of the ProtoDAC in comparison:
- Low end  not as focused
- less bite / punch (not as impactful)
- slightly less sparkle
- less wide of a soundstage

Very subtle differences but noticeable. 

Here are my questions:
- will the reclockers (Kali / Fifo) fix any of this?
- Will moving the power supply to the ProtoDAC PCB, instead of USBmicro have any affect?

FYI, I am using this as one of my reference tracks (if you click, it will download the wav file):

Thanks to everyone involved in this entire project (I have been a Moodie for a couple years now).
