    I think the initial incisiveness is causing me discomfort but from what it sounds like the Pi2AES smooths out after leaving it on for a few days. If I still find it too much I have a few ways to mitigate it. I can change out the tubes to a warmer set, eq, or fully switch over to the HD650 :p . I got comfortable with the HD650 yesterday in the bedroom and it was nice. That last sentence doesn’t sound right.

    :) "More incisive" is what my better-hearing better half said (in Portuguese rather than in English, but an exact translation) when I had her compare Pi2AES with Unison USB.

    I think what can happen sometimes is that when a component is too much one way or another for our tastes, we compensate in the other parts of our chain to bring it back to “balance” (aka, our preference). Too warm? Change something(s) that cools it off. Not incisive enough? Change something(s) that sharpens/tightens things up.

    Then when we change something that swings it the other way, we’re left to trying to balance it back again. If we can’t, or we don’t feel like changing other parts of our chain, sometimes we move on.

    I had something similar like this happen when I went from a single Vidar to dual monoblock Vidars - the monos are way tighter, squarer and more incisive and less warm and rounded than a single Vidar - too much for my taste initially. I was almost ready to dump the second Vidar when I realized that it was the tubes I had put in Freya - I had gradually moved towards really squarish and harder sounding tubes to compensate for the single Vidar’s “softness” (and probably somewhat softness in my speakers as well). Once I moved to softer more rounded sounding tubes with the monoblock Vidars, all was well again. One of the benefits of tube based gear I suppose - tube rolling is easier and cheaper generally than swapping other parts of the chain.

    In this case, Unison USB is a bit soft and bloomy compared to the Pi2AES SPDIF which is more incisive. The rest is, as others have said, probably burn in of the Pi2AES and your ears. Tube rolling may get you the rest of the way if you need it, but yeah I would wait a few days. A linear power supply is another option to smooth things off a bit.

    It's more likely your hardware burning in... Below I quote what meanwell says about it.

    https://www.meanwelldirect.co.uk/glossary/burn-in/

    No every board went through the same aging process. Some industrial stuff does before shipping out. That's one reason why I always buy medical (even better) grade psus when I can.

    Oscillators are affected by temperature more but if you really cared about it that much you should leave it on so temp is constant.

    Got the I2S over RJ45 adapter today. It's simple plug and play. It is compatible with Metrum DAC and I assume with Sonnet Morpheus.

    Got mine recently. Only complaint I have is that the plug on the Blue Jeans Cable digital RCA cable I'm using can't get a great grip on the Pi2AES SPDIF plug. The jack needs a little more length.

    Get a BNC-to-RCA adapter and you'll be set. The linked adapter has a locking mechanism which is nice, too.

    For those who aren't satisfied by the existing options: Even though MoOde doesn't support Roon, it is possible to install Roon Bridge alongside MoOde on the same Pi. I have them both running side by side with my Allo DigiOne Signature. You'll get some error notifications if both MoOde and Roon are trying to play music to the output device at the same time, but otherwise they coexist nearly seamlessly. It's not bugproof and occasional system reboots are required, but I haven't had excessive or annoying crashing. Unfortunately I don't remember the exact setup steps, but I recall it being pretty much as easy as installing MoOde, then installing Roon Bridge from the Pi's command line interface.

    Just want to add that for folks running RoPieee, the upgrade to RoPieeeXL takes about 4 minutes and is entirely painless. No need to flash a new card, you can initiate the upgrade through the local web interface.
