Now let me explain… behind the grandiose wording there is an exact science. Since this is a digital stream the most important aspect for "absolut best" is jitter. Jitter in digital domain directly translates into analog errors. Second, is noise. Lowering the noise that’s injected in your DAC will produce some (small-to-none) improvements. Allo have designed a digital (S/PDIF) transport for Raspberry Pi audio with one goal in mind: Absolut best S/PDIF output.

days of streaming. I’ve tried the original Node 2 and owned the Connect myself. What about the DigiOne Signature versus conventional streamers? 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. I hit upon using it as a Roon end point streamer as Pi’s can be used as such. As long as your Roon server is on the network the Roon app recognises it as ‘Volumio’ under Settings>Audio. The techie bit maybe? 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).

The DIYINHK works well but it is too expensive. You can buy a DAC for this price with just as good of a USB input. If this was a few years ago, sure, there would be a need for this when USB input was less common. Still, this may be a cheaper option for some to get better USB such as on Schiit DACs that don't have their "Gen 5" USB input. For a much cheaper option, you could look at Topping D10 which is a DAC but also has S/PDIF output. 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. Volumio supports Qobuz and Tidal but you have to pay extra for it. There are also various free Spotify Connect plugins for Volumio. I would like to explain a few things on the RCA output. The standard on coaxial is 75Ohm , unfortunatly RCA connectors and RCA cables are not capable of 75Ohm because of geometry/physics . We spoke to a few manufacturers of DACs and some of them already implemented 50Ohm impedance (since 75R is not possible) . Basically instead if doing text book , blind implementation , we take in consideration real world impendances and with a good DAC manufacturer 50R will be implemented on the RCA coaxial input But little precision. In digital world, SNR have no place (almost…). SNR is for analog part. Yes, you must have a good power supply, the only thing is to not have signal perturbation to high. I ever see lot of digital circuit running well with -6db of noise. In digital world this is binary : 1 or 0.

If someone had said to me 12 months ago that I could be getting this sort of SQ for such a modest outlay (excluding the Digione Signature), then I would have had difficulty in comprehending. 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.In our quest for digital perfection we asked how we can improve the design and give you the ultimate DigiOne. 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. Over the last few months I’ve also stared to accept that as much as I like them (good sound and a superb piece of furniture), it’s my speakers that are the “weakest” part of the system now. For some odd, bizarre, reason - based on no first hand experience at all - I am being drawn strongly to Tannoy dual concentric speakers and although the new “Legacy” range is far outside of my budget, I’ve put a few feelers out for original speakers from the 80/90s. I know of a couple of places where I could get them serviced, refurbed, etc. The main use of PRO3Z is to add USB functionality to older DACs without this input or improving the performance of the ones with poor UBS implementation.
