I am still using my USBridge on my headphone system. I like it a lot. I use the Shanti to feed both the USBridge Sig and my Hugo 2 DAC. My second one is going to go into a different system that is sill in the needs analysis phase! (Or mabye wants analysis) On my Kii Three system I have something different. There will be something posted soon on that! A bit more upscale! bob Ok thanks, I'll try MoOde. Do you mean I have to return the USbridge? I'm curious now, is it also more expensive than the USbridge, if so 10x? Link to comment

More later, “I do not want to steal my own thunder.” Looking forward to read about it. TBH I think the Kii Control + the digital path isn't influenced (much) by the source (if digital), that's also why I was hesitating to change my streaming. Due to some other reasons, mainly my htpc starting showing his age, I had to come up with a replacement and the USBridge Sig + Shanti should be 1 of the best transports and price is comparable with a Nuc, so I give it a try, but don't expect it to sound (much) better. Got the package (bridge + shanti) yesterday, came with Dietpi but didn't like it that much, so I installed MoOde as suggested and must say that works like a charm. Local music or Spotiy just sound very good. Need to do some more in depth listening and will do a comparison with what I had. For now I'm happy with it and it sounds really good, but the Kii BXT System always sounds awesome firedog 1 Link to comment

They tell you a lot! I agree it is not dramatic. The Allo USBridge Sig is really amazing for the price. The Kii Threes also benefit from AC power upgrades. My Audio Systems Link to comment

Guest Posted April 20, 2020 Share Posted April 20, 2020 Interesting 'review' of sorts. It appears that only MoOde was actually used for any length of time. I have been living with the AlloUSBridge for quite some time now, 6+ months. I've used it with Ropieee, Volumio, Dietpi, PiCorePlayer and my own build of Arch Linux + RoonBridge. Each one given a far shot at winning me over ie for at least a month. I used my own library, Internet radio, and Qobuz via RoonBridge. I powered it with a linear regulated PS and used direct Ethernet to compare it with the RPi 3+ and RPi 4 also with the same Software end Ethernet connections. My system consists of all Audiogd Master components. Master 7 Dac, Master 1 Pre and Master 3 amp combined with Dynaudio speakers. All wire is Duelund. My results were/are, the USBridge is inferior to both the RPi 3+ and RPi 4 when connected via USB output. I compared USB output only because Allo put so much tech and engineering into the USBridge for superior USB playback. This imo, is the calling card and the strong point of the USBridge, otherwise it is nothing more than a standard RPi3 in terms of all specs according to the RPi manufacturer. Each lengthy session of days and weeks produced the same result, a thinner, less full sound. Ultimately the sound was never engaging and always led me to switch back to either RPi 3+ or 4. My thoughts going into buying and using the USBridge was actually biased in favor of the Allo product, being smitten my all the USB tech and thinking/knowing that a superior USB design should/could provide a superior sound. I wanted this to be the case but alas it never came to be. Currently my Allo USBridge sits alone, powered off in the closet. Link to comment

Hi, Allo I have two on hand, one iFi USB power micro iUSB 3.0 -and- a LPS which uses an R-core PS [tests pretty stable] Only thing connected is: Power USB output Ethernet cable I didn't want to have any unnecessary variables contributing to the sound. Forgot to mention the power components; Furutech copper outlets Audiogd HE-350 Regenerative PS Professional Balanced Transformer All Power Cords are Duelund *Only the front end gets regenerated - balanced power [including the Rpi]* Amp plugged into the wall Link to comment
allo.com Posted April 21, 2020 Share Posted April 21, 2020 Ifi power is rather bad . The LPS what noise and power rating ?Do you have the make ? I will try to see if I can find any numbers (noise) on it. Its rather strange that RPI sounds better than USbridge sig , there must be a cause. My first instinct , there is an issue with the power feed . We designed Shanti with USBridge in mind. For example you say that your power is linear regulated, while thats fine generally , Shanti has a massive F capacitance at the output (after regulators) . Linear regulator does not behave best on a dynamic load, Alternatively , I am aware of the AudioGD hardware . While test results (THD) is not the whole story , this particular brand , tests rather ..bad. I am saying this , because a few months back I received a report that an AudioGD Dac paired with a Digione Sig was inferior to a rather low hardware (spidif signal) that was tested to have much more jitter on the output.

Yes I kind of figured that since the USBridge was designed to be superior that it must be my gear that was the issue. Perhaps when I can afford a better LPS and better audio gear I can give the USBridge another go.... Thank you for the reply. 😊 Here are the specs for the iFi power Link to comment
allo.com Posted April 22, 2020 Share Posted April 22, 2020 Ifi power on internal testing under real conditions (the numbers they quote are with isolation transformers) was about 6uV (including mains) from 0-20Khz However that is differential noise. In addition to differential noise (6uV is good) we have common mode noise and leakage currents noise . IFI psu , like any SMPS thats not earthed has (rather big) leakage current noise thats ,of course not accounted for .on marketing data . I do not recommend it . Link to comment

Very interesting Just so I understand correctly. Balanced power still produces "Common Mode Noise"? You might have missed it, like you missed me posting the model of the iFi product. All of my front end components including the sources are plugged into a Balanced Line Transformer, which in turn receives regenerated clean power from the Audiogd HE-350. I know that in your opinion Audiogd does not make good products, but from my understanding balanced power resolves common more noise problems. Link to comment

Yes, there is a way to do this, you can google it, but you'll need a CM in/out board, like this: https://www.waveshare.com/compute-module-io-board-plus.htm Link to comment
allo.com Posted April 23, 2020 Share Posted April 23, 2020 Hi Dyna the link from zackthedog is correct , thats what to use if you want to use a CM with eMMC. Regarding the power , I briefly spoke about common mode noise , I did not see excessive amount of it on IFI. Meanwhile I did focus on "leakage currents" and IF (like all SMPS without protective earth) has lots . I believe there are other threads on forums where the issue is discussed at lengths . There are even solutions (some wire on DC Gnd connected to earth) I think that AudioGD is an acquired taste (generally speaking) . One of my new Dacs (Revolution) has the ability to change harmonics (H2 and H3) amplitude and the perception of sound changes . Looking at most AudioGD tests the harmonics are different that most DACs (and rather very high) and its my opinion (not backed by any scientific data) that it has a particular sound . Usbridge Sig does output a very clean interface to any DACs and we are seeing a small change in H amplitude as a result . Maybe its just that a particular preference of sounds changes because of that.. I would try changing the IFI PSU, then try to get any other DAC and check if USbridge Sig brings an improvement .

GrahamJohnMiles Posted July 7, 2020 Share Posted July 7, 2020 Having listened to Moode on the Allo USBridge Signature Endpoint for a couple of days I just found it too muddy and syrupy with my Khadas Tone Board. Switching back to Ropieee, brought sparkle and dynamics back to the music. It’s all subjective. What works for one listener won’t work for another. Link to comment

GrahamJohnMiles Posted July 8, 2020 Share Posted July 8, 2020 Listening to Gentoo on the USBridge Sig. and finding it very nice indeed. Seems to be a little more clarity at lower volume, which is what I like in my smaller room. Took about an hour to get set up, the web interface is certainly different to the other OS’s out there so there’s a bit of a mindset change needed for a user. But overall, not an ordeal. Will give it an extended audition. Link to comment

Download the software, use Etcher or the like to write the image to a USB drive. Boot the USB drive on the target system. You can use the menu system via SSH or you can use a web browser to run the menus. Let us know what music software you would like to use. I can record a video or something to help with that. bob tims and lwr 2 My Audio Systems Link to comment
