Portable DAC/amps have always had a ceiling problem. The hardware inside gets you 90% of the way there — but that last 10%, the soul of a mix, keeps slipping through the cracks. Now, iFi Audio reveals the GR2 MT, a Master Tuned edition of its flagship portable DAC/amp developed alongside Grammy and Brit Award-winning producer Steve Levine. The verdict? This isn’t just a special-edition cash grab. It’s a genuinely different-sounding piece of kit — and at $699, it has the receipts to prove it.
The Quick Verdict
✅ BUY THIS IF…
- You own the standard GR2 and crave a more emotionally present sound
- You’re a serious headphone listener who values studio-grade tuning
- You want a portable DAC that doubles as a quality desktop unit
- You use high-end headphones that need serious power (1,513mW at 32Ω)
❌ SKIP THIS IF…
- You already own a premium desktop DAC/amp and rarely go mobile
- You use budget IEMs where component upgrades won’t be audible
- The $170 premium over the standard GR2 doesn’t fit your budget
- You need a straightforward audio interface for recording, not listening
What Actually Changed (The Honest Breakdown)
The standard GR2 ($529) was already a strong unit. Built around a Burr-Brown PCM1795 DAC, it packed Bluetooth 5.4 with aptX Lossless, balanced output, and a touchscreen. So what exactly did Levine and iFi touch?
A lot, actually. These aren’t cosmetic tweaks.
| Component | Standard GR2 | GR2 MT Upgrade |
|---|---|---|
| Circuit Board | Standard FR-4 PCB | Aerospace-grade hydrocarbon ceramic PCB |
| DAC I/V Stage | OVA2637 with surface-mount resistors | OV4627A with audiophile-grade tantalum resistors |
| Amp Capacitors | Standard electrolytic | Audio Note Kaisei capacitors |
| Digital Filters | Standard iFi filters | 2 Steve Levine-voiced filters (PCM + DSD) |
| Display | 2.3″ OLED touchscreen | Same + illuminated silkscreen logo |
| Price | $529 | $699 / £699 / €729 |
The Steve Levine Factor — Real or Marketing?
Steve Levine produced Culture Club, the Beach Boys, and Gary Moore. That’s a serious track record. And unlike most producer “collaborations,” he wasn’t just handed a device after launch to put his name on it.
He shaped two exclusive digital filters — one optimised for PCM playback, one for DSD — from the ground up. He was vocal about wanting a wider soundstage and stronger front-to-back imaging, describing it as “getting closer to the high-shakers” in a reference track. That level of specificity is hard to fake.
Could a different producer have made different choices? Absolutely. Will every listener prefer Levine’s voicing? That’s subjective. But the filters are real, and they’re paired with real hardware changes. That makes the MT a legitimate sonic experiment — not a sticker on a box.
“The goal of any producer is to document the authenticity and emotion behind the artist’s performance. I have voiced the iDSD GR2 MT with this same goal in mind.”
— Steve Levine, Grammy Award-winning producer
What the Press Release Doesn’t Tell You
Battery life is rated at around seven hours. That’s respectable for a unit this powerful, but real-world use — high-volume playback with Bluetooth active — will trim that number. Plan accordingly.
iFi also hasn’t published independent measurements for the upgraded analogue stages yet. The ceramic PCB and Audio Note Kaisei capacitors are genuine audiophile parts, but how much of that difference translates at normal listening volumes on typical headphones remains to be tested by reviewers in the wild.
And while Bluetooth 5.4 with aptX Lossless sounds impressive, remember: aptX Lossless only delivers true lossless 16-bit/44.1kHz when both your source device and wireless conditions cooperate. LDAC, despite its “high-res Bluetooth” reputation, is not lossless. If you want to connect to a quality pair of studio headphones, a wired USB-C connection will still be king.
How It Stacks Up Against the Competition
If you’re already running something like the Chord Mojo 2 or Astell&Kern AK HC3, the GR2 MT won’t be a revelation. Those units operate in a similar performance bracket, and personal preference will dominate.
But if you’re still running a dongle DAC off your phone or a first-gen portable amp from a few years back, the jump is massive. More headroom. A real touchscreen. Desktop mode that bypasses the battery when you’re at your desk — which also matters for long-term battery health.
For bedroom producers and content creators who use their portable DAC both at a desk and on the go, the GR2 MT’s hybrid lifestyle genuinely makes sense. It feeds into a broader, smarter setup — the kind you’d build alongside a solid home studio equipment checklist.

Who Is This Actually For?
Think of the GR2 MT as the ideal upgrade for the audio-obsessed multi-tasker. You work in a home studio. You take calls on the train. You listen critically to finished mixes on your lunch break. One device, intelligently made for all of it.
It pairs particularly well with planar magnetic or high-impedance dynamic headphones — the kind that need real power and reveal subtle differences in analogue circuitry. If you’re rocking premium studio headphones, this will let them breathe. If you’re on sensitive IEMs, you might not notice the MT upgrades at all.
For producers who care about how their masters translate outside of the studio — not just what a pair of studio monitors tells them — this is a tool worth serious consideration.
When iFi Audio reveals the GR2 MT, it’s making a specific argument: that the difference between good and great listening isn’t just the DAC chip — it’s everything surrounding it. The ceramic PCB, the Kaisei caps, the tantalum resistors, the Levine-voiced filters. That’s a $170 bet that component quality translates into emotional impact. Based on what we know, it’s a bet worth considering. Does the GR2 MT look like a genuine upgrade to you, or is the price gap over the standard model too hard to justify?
