Great! Let us know how it goes.

It's currently doing a passable job on Pink Floyd's "Division Bell," but it made Marvin Gaye's "What's Going On," sound a bit "thin," and rather unappealing. Early days though. Hopefully, the Pi 4 should arrive tomorrow and I can give that a bit of a run out.

Give it a week to burn-in. The ESS chipset will settle down and should give you remarkable detail.

Bummer! My Pi 4 has arrived, sans case. They're out of stock. I can get one on Amazon for £15 over the odds, or wait. I'm waiting.

At least you can run it without a case, proper breadboard builder style.

Volunmio flashed and loaded. I've just started the process to scan my approx. 1.8TB of files.

The good news is, Volumio sees my Digi2 Pro+ and is happily playing via its optical output. That's enough for tonight, I'll give it a decent seeing to tomorrow. The reason it's taken this long is that I was doing a bit of "housekeeping" on my Non Classical drive.

That sounds familiar, sidetracking yourself and watching time pass more quickly

The first thing I've learnt today is that you cant have both optical and 75Ω co-ax cables connected to the HiFiBerry Digi2 Pro at the same time and use the DAC to select which input it uses. That took a few reboots of Volumio to cure.
I've now got the co-ax (AudioQuest Forest) cable in place and I'm playing what is, admittedly, an old recording - Bees Make Honey's 1972 album "Music Every Night," - but it sounds good. Very "dry" in a good way, and very tight. Joe Bonamassa's "Royal Tea," is up next.

Well, this is interesting. It seems that Volumio is quite happy to see the HiFiBerry Digi2 Pro as a HiFiBerry Digi+ Pro (the previous incarnation of the card) as an i2s DAC board.
It does say, in the blurb, "HiFiBerry Digi2 Pro is a high-quality S/PDIF output for the Raspberry Pi. It uses the I2S sound port that connects directly to the CPU without the need for an additional USB conversion," but although I (obviously) tried it I never expected it to work. I'm still using the 75Ω co-ax cable into the DAC. It's interesting, but it complicates my testing by adding another parameter to it. It's currently doing a fine job with Gordon Haskell's "Harry's Bar," album, some of which is quite "intimate," vocally.

You shouldn't worry, it probably has the same protocols as the older board is all. The I2S is the route to good quality, bypassing the RPi's fairly awful USB subsystem.

It's highly probable, then, that my Schiit Wyrd, Oehlbach XXL, the two WireWorld Starlight 7 cables, and my AudioQuest Carbon USB cable, will become surplus to requirements, and the only decision will be between optical and coax. I've got an AudioQuest Diamond coax currently connecting the CD player, so I'm probably going to have to start researching "decent" optical cables. This " bargain" of a DAC is working out to be bloody expensive.

Try Stan Beresford's optical cable. It's very good when I tried it years ago.

Funnily enough I'd just Googled that, and the first link I came across was an old post by Fretless over at HFS. He used one, and was happy with it, but as usual thought he'd cast a wider net and setrtled, at the time, on a Profigold Oxypure. The Van den Hul Optocoupler Mk2 is another I've seen good words written about, if anyone knows it?

After a fair bit of to-ing and fro-ing, I've decided optical via the I 2S is the way to go, which surprised me a bit, and to that end, I've just done a very un-slinger-like thing and lashed out (almost) eighty-quid on a 0.6m optical cable. My shoddy logic tells me that buying what is hopefully going to be my end-game optical cable will save me £50.00 in the long run by buying it now, rather than spending £50.00 or so on an intermediate cable, and then deciding to step up again later on. Obviously, I can only go by the dreaded reviews, but they do seem uniformly good. Once again (as with my WireWorlds) I've bought my digital cable from Analogue Seduction. Oh, sorry, it's one of these... www.qed.co.uk/qed-reference-optical-quartz-digital-audio-cable.html#tab1

Hope it works well for you, Paul. AS are a good vendor.

My new cable has arrived, and I'm a bit annoyed. Would you believe that a 0.6m cable came packed so that it was far too large to fit through my letterbox? It was in a huge padded envelope, and inside that was a heavy cardboard sleeve, inside which was a heavy cardboard tray, covered by a separate plastic and cardboard window-cum-lid. Hardly what one hopes to see when we're all supposed to be going greener. Anyway, the cable itself is satisfyingly chunky, with heavy, metal, plugs. Note the punctuation. They are heavy, and they are metal, they are not Heavy Metal. As soon as I've finished watching last night's "Manhunt: The Night Stalker," I shall actually plug it in.
