Allo USBridge Signature

[Manni]

Have you noticed any quality differences between this network play VS local drive (HDD/pendrive connected to USBridge Sig). @Allo, what is the recommended setup? 
I'm thinking to add a powered HDD (desktop style backup drive with external power) directly to Allo... I hope this will improve quality over the network upnp route.. any comments please...

I have only compared 16/44 and 24/192 files from NAS (Synology DS214play with 2x 4 TB WD RED) vs 16/44 and 24/192 from USB stick. 
DS is connected to my Fritzbox router via 1m Cat5, from Fritzbox via approx 10m CAT5 to groundfloor listening room to Allo USBridge Sign. 
Booth devices, (DS NAS and Router) have standard switch mode power supply.
If there is a difference in sound, it is small, but in favor of the USB stick. Have not tested to load a music file on the SD card yet.

The sonic differences of different USB cables from the Allo to the Chord Mojo DAC is much much more obvious.

Even the Allo USBridge should have a "clean" USB-out, this can be improved with my Intona Industrial USB Isolator.
I have been a bit disappointed in this regards, as I hoped I could eliminate the Intona USB Isolator. 
The USB-out signal from the Allo is not a lot "cleaner" as the USB-out of my MacBookPro running from internal battery and Sys-optimized from Audirvana 3.5.x.
Do not want to start a cable discussion here, but to my ears and with my gear the USB cables matters a lot.
I'm using JCat Signature USB cables. 1m A-B from Allo to Intona and 0,5m A-MicoB from Intona to DAC.
Before I had tried and owned a few of the known, like  Audioquest, Wireworld, MoonAudio, Supra, etc.
Only the Intona and JCAT sounded "right" to my ears, all other USB cables have some kind of "sound" signature. 
Just my 2 Cents -

PS: My definition of "sound signature":
Every cable (... and component) deducts (takes away) or adds (distortion) something to the "original" signal.
The more this happens, the more our brain has to work hard to eliminate (distortion) or substantiate (missing information) it for our "listening" session.
When my wife comes into my listening room and wakes me up and asks me: "how can you sleep with this loud music"
- well, then I know the cable (component) is okay, since my brain did not have to work very hard - it was quite relaxed .... -
