Metrum Onyx versus Metrum Pavane

I can’t comment on the Pavane but I feed my Onyx from the baby Ambre via spdif and it sounds better than when I had the USB connection from SoTM sms-200 (which was itself improved when I went through a schiit eitr to convert to spdif prior to getting the baby Ambre!) simpler is better, hence replacing both SoTM and eitr with baby Ambre. I still plan to go i2s from regular Ambre at some point in the future.

Hi guys! I am interested in the Metrum dacs, but I have a few concerns. Can you detail a bit how the two (Onyx and Pavane) stack up to each other as well as in absolute terms with respect to:

a) the soundstage width (I’ve read that Onyx is quite narrow, I can’t stand anything narrow) and

b) HF extension (I don’t need / like a piercing treble, but I can’t stand a rolled off one, I need to hear all the beautiful HF resonance of a lightly hit triangle decaying naturally, for example, instead of cut short or borrowed in the mix)?
Please if possible mention the inputs and outputs used in your comparison. I’d probably use a CD transport via electrical SPDIF and both the unbalanced and balanced outputs.
Oh, by the way, can something like Ambre be also used for playing music from the computer’s HDD? Sorry if this is a dumb question...

Thanks!

...Anybody?!

I stopped reading after you said, "Ive read that Onyx has a narrow soundstage" 

Why, you disagree with this assertion?The impressions I've read are quite contradictory in this regard - hence my specific questions above. Please, feel free to contradict this statement.

To put things in perspective, when I had the Gungnir Multibit in my system for a few weeks I Ioved many of its sound traits but wanted a wider stage, much blacker background, better treble extension (the stuff above ~10kHz, probably), a more relaxed, effortless presentation (difficult to put it into words, it was a bit as if I was kept in a bit of a tension all the time, perhaps something similar to how I felt about my ex AKG K1000 / D class amplifier as opposed to the effortlessness my Stax) and maybe just a little thicker tone (but this latest thing might have been more a matter of synergy). All heard in a couple of solid state systems + my Stax headphones. It was the (supposedly) latest, unofficial "A2" version (November 2017), kept on all the time and with more than 200 hours of burn in.
