I‘m sure there are much better streamers out there, able to improve massively on my set up - I don’t dispute that. Probably, though, I’m never going to get to hear them and even then, I would probably still opt to spend additional cash on other items of hi fi kit. Our transports have different outputs. USBridge is feeding your DAC through USB and DigiOne is using coaxial/bnc. Depending on your DAC inputs you need to make a choice. As good a DAC as it is, I don’t think I could have justified buying a new Modius when I was more than happy with the Modi 3. In fact, for me the situation would be even more clear cut now as Schiit have released a Modi 3 plus, with their “Unison USB” connection. days of streaming. I’ve tried the original Node 2 and owned the Connect myself. What about the DigiOne Signature versus conventional streamers?

To me, the DigiOne (or DigiOne Player, if you look for a complete player) are the best choice possible as of now if you own an S/PDIF DAC, or if you know for sure that the implementation of S/PDIF receiver in your DAC is superior than the USB side. Volumio supports Qobuz and Tidal but you have to pay extra for it. There are also various free Spotify Connect plugins for Volumio.

Lower electrical noise and lower jitter make for less mechanical-sounding D/A conversion music, which we hear from better-sounding transports like the AURALiC Aries (Mini), the Wyred4Sound-modded Sonos Connect and Sonore’s ‘Rendus. Each of which offers, to varying degrees, a smoother, more easeful presentation where new sounds are seemingly birthed more effortlessly. For this commentator, these are the hallmarks of higher quality digital audio transmission. We see identical performance from both, substantially lowering the jitter and noise products from Schiit Modi 2 Uber. What is left from prior testing, is due to deficiencies in the rest of the Modi 2 Uber DAC than anything to do with digital input jitter.

I have been playing with the DigiOne with almost a month now, and I’ve been able to listen to it with a variety of DACs I do know well. DigiOne has 2 outputs: BNC and plain RCA (coaxial). On both, we have achieved jitter of 0.6ps (1 picosecond – time taken by light in a vacuum to travel approximately 0.30 mm). Whilst it’s hard to imagine a JustBoom owner being disappointed by the sound of the Digi HAT, if you’re able to stretch your budget, the Allo DigiOne board delivers disproportionately more of the good stuff. So if you want a leftfield idea, in a quirky looking product, and to get maximum performance instead of conventional streamers, it’s definitely Allo Allo with the DigiOne Signature. Just make sure you use the correct power supply combination. Very recommended and it achieves the 13th Note for the money! Manufacturer Recapping, if the JustBoom HAT’s coaxial is the equal of the AURALiC Aries then the Allo DigiOne surpasses it; a polished ease making more agreeable work of listening to The Jesus and Mary Chain’s “Teenage Lust” or Throwing Muses “Bright Yellow Gun”, just as Wyred4Sound’s souped-up Sonos Connect does.The feeling initially is that the Yamaha WXC-50 is actually pretty close to the Allo DigiOne Signature. Good bass response, nice detail and dynamics. A test between the DigiOne Signature connected solely with the Shanti and the Yamaha, might to some impress the Yamaha as being *better* on account of unsmoothed credentials. Output is coaxial/BNC and rise/fall time is 1ns and voltage level is exactly as per guidelines (550mV on coaxial) measured at end of transmitting cables The second fatality is TOSLINK. According to Allo engineers, “[TOSLINK] by definition has a jitter of 4ns. That’s 4000ps”and “[it] had to go”. On the DigiOne we note coaxial and BNC outputs.

Anyway, things then progressed and because I could afford to, rather than needing to, I progressed to a DAC board for the PI. Although I know there are several options on the market, I opted for the ALLO BOSS DAC v1.2. Again, as far as I was concerned, SQ was the best that I’d heard to that date. Fast forward again - the BOSS DAC was sold and in its place a Schiit Modi 3 DAC (see John Darko’s video for the reason why). About 3/4 months later, I had the opportunity to trade up to a 2nd hand Schiit Modius which I did. this DAC is with me still (at the moment anyway - and until GAS takes over again). Of course, since this is based on RPI compute, we decided to include the standard RPI connector. Anything that works on an RPI will work on the USBridge Sig. For example, you can use a DigiOne / DigiOne Sig to make a full fledge streamer that outputs USB, BNC and coaxial. PSU: Not needed (power is taken from RPI, then we use a isolated DC/DC convertor with filters and LDO)I know there is one manufacturer that claims 75R on the cable (I think its canari cables) but still your connectors will be 50R thus defeating your cable impedance. To do this pimping it uses two extra boards mounted on top of the bottom layer Pi, in a kind of sandwich. Already this language could have an entirely different connotation on a different part of the internet… Anyway, normally a Pi can be configured with a micro USB input for power and Ethernet input to get internet for music streaming services, and a USB output to your DAC. Its operating system comes not so much on a ‘wafer thin mint’ SD card type, but in miniature micro SD card guise. Choose the operating system you want and off you pop. If you like the comfort and versatility of streaming your music via Raspberry Pi, but your appetite for a slightly cleaner digital source grew past it, Allo DigiOne might be just the thing you need. months ago, I didn’t have a streamer. I’d always wanted to “do something” with a Raspberry Pi (being reasonably IT literate) but never got round to it. Deciding I could use it as a streamer was the justification I needed.
