MAGNI 3+ Impressions
In summary: A rather good headphone amplifier, … actually, quite remarkable for its size and price. A great achievement by
@Jason Stoddard and the Schiit team.
I’ve been following progress of the Magni range over the years, but this is my first purchase, although I own other Schiit (see sig). Jason’s Heresy story got me intrigued and so I plumped for the M3+ as I’m a fan of discrete designs … all that engineering from scratch is awe-inspiring. I’m not really a measurements person, so, I’ll take it as read that they are good. Who am I to argue with them! More importantly to me … how does it sound ?
Initially, I connected the M3+ to the Gungnir MB (in place of the Mjolnir 2) in my main system just to see how it would sound paired with a reasonably top-notch DAC. Headphones were AEON Flow Open (Gen 1), Sennheiser HD650 and Sennheiser (Drop) HD58X … so, my comments are largely with this set-up. I listen mainly to jazz and some classic rock. All comments are my own, personal opinions and you may hear things differently with alternative set-ups.
I felt that the M3+ benefits from a few hours of initial run-in … things smooth out after about 15 hours or so from new, IME.
Right from the off, this is one ballsy, full-bodied amplifier that belies its size and price. There is a pleasant weight to the overall sound presentation and, noticeably, plenty of low-end heft.
Detail is good, even low down, and instrument separation is excellent. Acoustic double-bass is articulate, and the notes are easy to follow. Piano has that satisfying ‘grrrrunggge’ in forte, like a piano should sound, although I do detect some occasional shrillness in upper-mid piano block-chords (think Oscar Peterson). Saxophones reveal their sound textures well, as do guitars, which is important to reflect the expressiveness of the musicians, both in jazz and rock.
The sound stage is not super-wide but perfectly adequate and perhaps not as deep as I’m used to. The stage is fairly close to the listener and perhaps in an ideal world it could be a couple of rows further back.
Headphone pairings:
AEON Flow Open – The M3+ can certainly drive these magnetic planars well, with plenty of detail and bass. However, I felt there is a slight warmish tinge to the sound in this set-up which I don’t hear with my other amps (Mjolnir & Gilmore)
Sennheiser (Drop) HD58X – These easy to drive dynamic headphones sounded at their best with M3+, compared to my other amps. They are relatively inexpensive and could well be a good choice for M3+ owners.
Sennheiser HD650 – These are my preferred pairing … the M3+ cuts through the HD650’s traditional weaknesses effortlessly. The resulting sound is both relaxing and involving. A musically enjoyable experience that verges on the majestic! .. to my ears.
Jason claims that the M3+ (and Heresy) is “... all the amp you’ll ever need”. So, how does it compare against others?
I don’t have any amps at a similar price point, but that didn’t put me off! The cheapest amp I have is a $249 AUNE X1s (a Dac/Amp, actually). The M3+ knock spots off this, so I won’t go any further with that comparison.
More appropriate is the Gilmore Lite MK2 (by HeadAmp), a discrete design, Class-A amp, producing a maximum of 1.5W of power (much lower), BUT nearly 5 times the price of the M3+. My preferred headphone pairing with the GL2 is AFO, closely followed by HD650 … both are excellent.
So, what does an additional $400 buy you? There are 3 main areas that are different, IMO, by comparison …
The overall sound of the GL2 comes across as more neutral, clear, transparent and refined. That said, the M3+ has more weight/heft to its presentation than GL2.
On the GL2, there is a greater amount of airiness around the instruments and the sound-stage is both wider, deeper and a bit further back, with more background (ambience) detailing. Transients also seem faster.
Instruments sound a tad more nuanced with even more clarity, and detail on the GL2. At the bottom-end … for example, notes on a low-B string on an electric bass guitar, are better defined. At the top-end, cymbals ‘ting’ more convincingly and splashes are that bit more realistic sounding. Mids are about equal, although the extra weight of the M3+ gives it a pleasant edge.
These two amps are not a million miles apart, but noticeable differences to my ears nonetheless. I wonder how M3+ compares with the new Asgard 3 … would be interesting to hear from anyone that has done that comparison.
So, is it “... all the amp you’ll ever need”? Yes, it probably is all you NEED. At its price/performance point it will be hard, if not impossible, to beat. A great achievement by Jason and his team.
