Short answer: the FiiO K11 R2R (~$170) is the best DAC/amp combo under $200 in October 2026. The two units that used to share the top of this list, the FiiO K5 Pro ESS and Topping DX3 Pro+, are no longer made.
R2R DAC, 6.35mm + 4.4mm balanced outputs, about 8 V into 300Ω balanced (FiiO spec). The one box that covers HD 600s and budget planars under $200.
$199 with the internal DAC: 2.5 W into 32Ω and about 11 V into 300Ω single-ended. More voltage than the K11 R2R, no balanced jack.
New compact DAC/amp: 1 W into 32Ω, 230 mW (about 8 V) into 300Ω, 4.4mm balanced, and a mic input for gaming (specs per StereoNET).
Side-by-side
HD 600 target: 2.45 V for 110 dB peaks. HE400SE: 80 mW.
| Product | Price | Into 32Ω | Into 300Ω | Balanced out | Inputs |

| FiiO K11 R2R | ~$170 | ~1.3 W bal. / ~0.5 W SE | ~220 mW bal. / ~50 mW SE | 4.4mm | USB, optical, coax |
| Schiit Magni (Unity) + DAC | $199 | 2.5 W | 415 mW | No | USB (with DAC card), RCA |
| Topping DX1 II | $119 (launch) | 1 W | 230 mW | 4.4mm | USB-C, optical |

The picks
1. FiiO K11 R2R: best overall
FiiO’s current entry desktop unit, and the effective replacement for the K5 Pro ESS. The balanced 4.4mm output is the one to use with 300Ω headphones: about 8 V and 10 dB of headroom over the HD 600’s needs. From the 6.35mm jack it’s about 3.9 V, which still works with roughly 4 dB to spare. Into planars, about 1.3 W balanced is many times what an HE400SE or Sundara needs.
Skip it if you want Bluetooth or a remote; those start with the Topping DX5 II (~$299).
2. Schiit Magni (Unity) with DAC card
Schiit’s single current Magni can be ordered with an internal DAC card, which Schiit’s site prices at $199 total. You get one box with Magni power (415 mW into 300Ω, under 0.1Ω output impedance) and preamp outputs for powered speakers. It has no balanced headphone jack, but at 11 V single-ended it doesn’t need one.
3. Topping DX1 II: the compact pick
Topping’s replacement for the DX1 launched in July 2026 at US$119. StereoNET’s launch report lists 1 W into 32Ω and 64Ω, 230 mW into 300Ω (about 8.3 V, roughly 10 dB of headroom on an HD 600), 3.5mm and 4.4mm balanced outputs, USB-C and optical inputs, and a microphone input on the 3.5mm jack. That last feature makes it the cheapest current pick here for gaming with a headset-style mic. Note the 3.5mm jack: full-size headphones need an adapter or a 4.4mm cable.
The original DX1 (about 51 mW into 300Ω) was still listed at $99 at Apos on October 10, though sold out. If you find one at that price, it drives an HD 600 with about 4 dB to spare.
Worth stretching for
- iFi Zen DAC 3 (~$229). USB-powered, 4.4mm balanced, and iFi’s PowerMatch gain boost. iFi rates the balanced output above 300 mW into 32Ω and above 70 mW into 600Ω (about 6.5 V). That’s fine for HD 600s balanced but marginal single-ended. USB-C is the only input. See today's price for the iFi Zen DAC 3 on Amazon ↗
- FiiO K7 (~$220). No longer on FiiO’s website but still sold new. 2 W balanced into 32Ω, AKM DAC, more inputs than the K11 R2R. Worth it only on a discount, since the K11 R2R matches it for most headphones. See today's price for the FiiO K7 on Amazon ↗
For gaming with a mic
The Schiit Hel 2E we listed here before is no longer on Schiit’s website. Schiit’s current gaming units are the Fulla ($109) and Gunnr ($229), sold direct at schiit.com, and the Topping DX1 II above has a mic input. For a gaming setup built around audiophile headphones, see best headphones for gaming (audiophile picks) .
What happened to the K5 Pro ESS and DX3 Pro+
- FiiO K5 Pro ESS: discontinued. B&H and other retailers list it as no longer available. The K11 R2R replaces it.
- Topping DX3 Pro+: retailers list it as discontinued. Its Bluetooth-and-remote role now belongs to the DX5 II (~$299); see the under-$300 combo guide .
The old reviews stay up for owners: K5 Pro ESS , DX3 Pro+ .
Separates or one box?
One box makes sense for a first setup: one USB cable, one power cable, done. Separates make sense if you already own half the chain. The Schiit Modi 5 ($149) + Magni (Unity) ($119) stack is $268 at Schiit’s prices, more than either combo above, so buy separates for flexibility rather than to save money. See the best DAC under $200 for standalone DACs.
Who should not buy a combo
- Owners of an audio interface with a decent headphone jack: check the voltage table . A Focusrite-class interface may already be enough for 80Ω headphones.
- Phone-only listeners: a dongle or Bluetooth receiver suits you better. See best portable headphone amps .
