So, about that Piety…
For tits and pickles, I did a little shootout yesterday.
I had sitting before me a Magni Piety, a Magni 3+, a Magni 3 Heresy, a Vali 2+ with a Genalex GoldLion, and a Jotunheim 2. To give all of them the best chance I possibly can, I’m feeding them with my Yggy OG. Headphones are a pair of DCA Æeon2 Noir (13 ohm closed planars). There's also a Lokius in the chain, set to 2:30, 1:30, noon, noon, noon, noon. Yes, I like me a little bit of extra bass. I am streaming Qobuz via Roon on a M1 Mac mini via USB to the Yggy. The Yggy goes balanced into Lokius (Snake Oil Taipan XLR), and from there single-ended into the headphone amps (Snake Oil Taipan RCA). To connect the Noirs I am using a bog-standard 4.5ft Hart Audio HC-12 with ¼" TRS interconnect.
The music used is my usual go-to playlist of reference tracks, which is a somewhat eclectic mix of classical, rock, folk, pop, acoustic, live jazz, and electronica.
First up: Magni Heresy. Just forget about it. Sounds thin, flat, closed-in to the point of being outright veiled, and lacks enough oomph to drive the Noirs to their potential. Bottom end is sloppy, highs are too sharp, mids are boring. Does it sound better than my iPhone’s internal DAC? Sure. Tons better in fact. But it’s just not good enough for what we've all been conditioned to expect from Schiit by this point. My least favorite out of these five.
Magni 3+ is a solid step up. Still a bit too weak to properly drive the Noirs, but at least the bottom end is tighter and the highs are more pleasant. The mids are ok, if lacking just a tad in spacial definition. Overall, things are still quite a bit too closed-in for my taste, there’s just not enough spacial presentation. Quite good for the 99 USD it had once cost me when I bought it, but nothing to get too excited about.
Vali 2+ with the GoldLion takes care of most of the issues I have with Magni 3+ and Magni 3 Heresy. There’s plenty of power to make the Noirs sing, and its spacial presentation is magnificent given the tiny form factor. The highs are airy without being needly, and the mids are well-defined and have good separation and placement. The bottom end is present and comes with enough volume, although it's maybe still a tiny bit too sloppy. Not enough to be a dealbreaker, though. A solid purchase, especially with the right tube.
Up next: Jotunheim 2. Why even is this amp in this shootout, you might wonder? Because it shares its topology with Piety and I'm curious whether that means that it would sound similar. To keep things somewhat comparable, it, too, got fed with a single-ended signal, and the ¼" TRS socket was used.
So … well?
The Jotunheim 2 has power for days, of course. But I always thought that it is overall a bit dull. The bottom end is fast, but that’s where this amp's strengths end for me. The mids lack definition and the highs I always found to be fatiguing. Overall, I could never quite shake the impression that the amp is just too closed-in and veiled-sounding. I'm fully aware that most people will strongly disagree with me on this and will insist that the Jot 2 would be crisp and open. But I have the same issue with Bifrost 2 being too closed-in and veiled for me, and the majority tends to avidly disagree with me on that one, too. So maybe it’s just me.
Now to the Piety…
You can tell that it shares common roots with the Jotunheim 2 because it, too, has power for days.
But that’s where the similarities end.
Piety is open and airy, and the overall presentation is stunningly accurate and well defined. Considering that it’s „only“ single-ended, the accuracy in placement and space it provides is surprising. The only headphone amp I own that does better in this regard is my treasured Mjolnir 2.
Highs are present and airy, but still really very pleasant. I can easily see myself listening to this amp for many hours without a break and not get fatigued by how it deals with treble. In fact, I've been listening to the amp all day today, and 12 hours in, I'm still not tired of it. Again, something that only the Mjolnir 2 and Folkvangr were capable of providing until now.
The mids are perfect. They are absolutely spot on. I’m trying to find something to complain about, but there’s nothing. I can't overstate how well this little amp does here. Instruments are well separated, detailed, clearly defined in space, and at least to my ears pretty much completely flat in their response along the entire frequency spectrum. No bloom, no dip, no hump — almost analytical, but in a really pleasant and somewhat warm and welcoming way.
The bottom end is fast, and there’s not so much as a hint of sloppiness. Transients down low are not quite as accurate as Tyr's, but much, much better than anything else I’ve heard in that price range or at that size, and are pretty much on par with what Mjolnir 2 delivers.
But that’s not the end of it, not by a long shot. Piety has another party trick up its sleeve! Engage high gain — and all the things it does well that I’ve mentioned above get turned up to eleven. Apart from Folkvangr, I’ve never liked high gain on any of Jason’s designs. They usually just get harsher in their presentation, but not better. But with this little thing here, high gain makes this give even the Mjolnir a run for its money. Everything becomes more defined, more precise, fuller, punchier, yet still no harshness anywhere.
Forget about low gain, get rid of the switch and save yourself the 25 cent in materials. High gain should have been the only mode, period.
In short: I am completely blown away by this thing. I honestly think that Jason made a mistake by „giving away“ this design to a third party. I know that he had good reasons to do so, but it's still a bit of a shame that this will remain a limited run. If this were fully balanced, it would be the Jotunheim I’ve always wanted.
Screw people's opinions on measurements, and screw that "magical" 99USD price point. This is the Magni that should have been.
