The short version

What to know.

Schiit's $149 single-tube hybrid headphone amp and preamp. Broad agreement that it is a serious amp for the money: 1.5 W into 32 ohms and 400 mW into 300 with a 0.5-ohm output impedance, quiet enough for most IEMs on low gain, small, cool-running and built in Texas. The maker's own bench report is unusually candid — 0.005 % THD on low gain, 0.3 % with a dominant second harmonic on high gain — and that switch is the key to the disagreements. Roughly half of the weighted opinion hears a clean, solid-state-fast core with a restrained tube seasoning in the mids; a quarter hears an amp so close to a Magni that the tube is decoration; a quarter hears colouration they dislike, from soft one-note bass and congestion to bright, dry treble. Opinion splits on whether rolling the cheap 5670-family tubes changes anything audible, on whether it is dead quiet or faintly noisy (tube, gain setting and IEM sensitivity decide), and on build, where a minority of loose-cover and dead-unit reports sit against the majority's 'built like a tank'. Value is called a no-brainer by most, merely good by a sizeable camp, and not worth it by a few who returned it. It is not a Susvara amp and it is not an OTL.

About this product

The third-generation Vali (March 2024, $149 black / $159 silver), which replaced the Vali 2++ at the same price. One 6N3P tube (5670, 2C51, CV4013, 6CC42 and WE396A also fit without adapters) at 100 V on the plate for voltage gain, into a discrete Class AB bipolar output — a hybrid, not an OTL; single-ended in and out with RCA preamp outputs. Not the Vali 2/2+/2++ (60 V, 6922-family tube) and not the $499 all-tube Valhalla 3.

The Vali has been Schiit's cheapest way to put a glowing bottle on a desk since 2013, and it has always been a hybrid: a small tube does the voltage gain, transistors do the heavy lifting. The Vali 3 keeps that recipe and the $149 price of the Vali 2++ it replaced, but runs its single 6N3P at 100 volts on the plate instead of 60, moves the headphone jack away from the knob, and takes the cheap Soviet 6N3P and the American 5670/2C51 family — the fabled Western Electric 396A included — straight into the socket.

It arrived in March 2024 to almost no magazine coverage and an enormous amount of forum traffic: a Head-Fi thread that has passed 7,000 posts, most of them about tubes. Two and a half years on, the field agrees it is a lot of amp for the money and still argues about the only question that matters for a tube amp — whether it actually sounds like one.

A good fit for

First tube amp on a budget — a cheap, quiet, low-output-impedance way to hear what a second-harmonic-heavy stage does, with a reversible experiment built into the gain switch
Sennheiser HD 600/650/6XX and ZMF owners who want a bit of tube character without an OTL's output impedance or price
Planar owners: unlike an OTL it drives Arya, Sundara, Edition XS, Aeon and even HE6-class loads
Desks that need a compact preamp for powered monitors or a Gjallarhorn as well as a headphone amp
Anyone who enjoys rolling cheap tubes — the 5670/2C51/6N3P families cost $2–25 and drop straight in

Think twice if

You want obvious, gooey tube warmth on stock settings — a Valhalla 3, Bottlehead Crack or xDuoo OTL does that; this mostly does not
You are buying it because you think a $149 tube amp will sound clearly different from your Magni or interface — a sizeable camp could not tell them apart
Your main headphones are Susvara-class or you need balanced connections, a remote or a DAC in the same box
You use very sensitive IEMs and want a wide, quiet volume range — you will live at the bottom of the pot on low gain, and some tubes hum on high
You would rather not gamble on a tube hobby — several owners spent far more on 5670s and 396As than on the amp

1.5 W into 32 ohms and 400 mW into 300 through a 0.5-ohm output: it drives HD 600/650s, ZMFs, Arya Stealths and most planars with room to spare
On low gain it measures like a competent solid-state amp (0.005 % THD, 120 dB SNR); on high gain it measures like a classic tube amp with a dominant second harmonic — the switch matters more than the tube
Clearer, less grainy and better staged than the Vali 2/2+/2++ it replaced; nearly every owner of both says so
Quiet with most IEMs on low gain, and low-volume channel balance is much better than on earlier Valis
The stock NOS 6N3P is a good, quiet tube; the GE JAN 5670W (~$20) is the thread's consensus first upgrade
Small, cool-running and the headphone jack now sits away from the knob; the power switch is on the back
Single-ended only, no remote, no DAC, and there is more gain than sensitive headphones need
A hybrid, not an OTL: nobody who has owned a Bottlehead Crack or Valhalla calls it the same kind of tube sound

Points of contention7

Does the tube do anything? Half the weighted opinion hears a clean core with real tube seasoning, a quarter hears a Magni with a bottle on top, and a quarter hears colouration they dislike — from soft bass to bright, dry treble
Whether rolling the 5670-family tube changes anything audible — blind-testers say almost nothing, evangelists say a $25 GE ends the amp upgrade path
Whether high gain is 'the tube setting' (less feedback, more character) or simply the noisier, more distorted one you use only when you must
How quiet it is: silent with Andromedas for some, a faint hum, hiss or microphonic ping for others — the tube, the gain switch and IEM sensitivity decide
Whether it has the power for the hardest loads — owners run Tungstens, HE6se V2s and a Susvara on it, while others found it short with very high impedances or full-size cans
Build: 'built like a tank' versus a minority of loose covers, a loose power connector, dead units and dead power bricks
Value: a no-brainer, merely good, or not worth it against a $119 Magni — all three camps have owners who lived with it

Sources split three ways on what the tube is doing. The largest camp hears a clean, fast core with a restrained tube flavour — 'midrange magic' rather than warmth, with less glare than a cheap solid-state stage and none of the murk of the Vali 2++ it replaced. A second camp hears an amp so close to Schiit's own Magni that the tube is cosmetic — level-matched against a MOTU interface or a Magni Piety, several owners could not tell them apart. A third camp hears colouration and does not like it: congested, rough-edged transients and a small stage at SBAF; soft, one-note bass and lost detail on dense mixes; and, from two early returners, a bright, dry treble with more glare than a Magni+. The split tracks the gain switch, the tube and the load (see the measurement note).

Measured

Schiit's APx555 report (a representative unit, 1 V into 300 ohms): on low gain 0.0052 % / 0.0068 % THD+N per channel with the second harmonic at −84 to −86 dB and everything above it below −110 dB, 120 dB A-weighted SNR and ±0.01 dB frequency response; on high gain 0.30 % / 0.36 % THD+N with the second harmonic at −49 to −51 dB, the third at −81 to −84 dB and a cleanly descending series after that, 106 dB SNR, ±0.03 dB response. The preamp output measures like low gain. atomicbob's independent sweeps at SBAF show the same descending-harmonic signature and that a 32-ohm load raises distortion further than 300 ohms does.

vs. listeners — Both the 'sounds like a Magni' and the 'unmistakably a tube amp' camps are describing the same box on different switch positions: low gain measures like a competent solid-state amp, high gain measures like a classic tube amp with 57x the distortion. Add a low-impedance planar or IEM (more distortion) or a 300-ohm Sennheiser (less), and the stock 6N3P versus a GE 5670W, and reviewers were rarely listening to the same amp. The third camp's complaints — soft bass, congestion, glare — are not what the harmonic spectrum predicts and are best read as pairing and preference, not a measured fault.

Where it splits

“I mention this on purpose, because the overall sound temperature in the case of Vali 3 is not as warm as many may expect. In the absolute terms it obviously goes into that lush side of things, yet the sonics here are rather on the clear side.”
Adam Kiryszewski · hifizone.pl

Far more than its size suggests, and the reason most owners bought it: 300-ohm Sennheisers and ZMFs sit at nine o'clock on high gain, 13-ohm Aeon Noires and 5.6-ohm Hinodes play cleanly, and owners report driving the Mod House Tungsten, HE6se V2 (high gain, two o'clock) and even a Susvara acceptably. The limits camp is smaller but specific: one long-time OTL owner finds it struggles with the very highest impedances compared with a Valhalla, one owner's full-size headphones needed two o'clock on high gain and sounded better swapped for IEMs, and a 250-ohm DT 990 owner got no more headroom than from a Little Dot. Schiit itself says it is not ideal for Susvara-class loads. One 'it doesn't get loud' complaint on Reddit turned out to be a 0.5 V gaming DAC feeding it.

Measured

Schiit rates 1.5 W into 32 ohms, 1 W into 50, 400 mW into 300 and 200 mW into 600, all at under 10 % THD because it is a tube hybrid; gain is 1x (0 dB) or 5x (14 dB) and output impedance 0.5 ohms on low gain, 1.8 on high, so damping is never the issue an OTL has. The maker's FAQ says it 'may not be ideal, say, for Susvaras' and that Class A operation is only 30–50 mW, so 300–600-ohm headphones stay in Class A far longer than 16–32-ohm ones.

vs. listeners — The published figures put the HE6se V2 and Tungsten at the edge, which is exactly where owners report them: playable on high gain near two o'clock, with a Jotunheim 2 giving more dynamics. The high-impedance complaint is about an OTL's voltage swing into 300–600 ohms, not a fault the 0.5-ohm hybrid shares; the 250-ohm headroom complaint is a bass-heavy, EQ-boosted listener.

Sources split, and the split is about the tube and the switch more than the amp. A clear majority — including a reviewer with Andromedas, an owner with 5-ohm all-BA IEMs, and atomicbob's bench — find it silent even with sensitive in-ears on low gain, with low-volume channel balance far better than earlier Valis. The other camp reports a faint hum on high gain, a buzz when the chassis or a non-stock knob is touched, microphonic tubes that ping when the desk is tapped, and IEM noise that sent one owner back to a Magni for in-ears. Nearly every one of those reports names a particular tube or the high-gain setting; the stock 6N3P is repeatedly called the quietest tube of all.

Measured

Schiit's APx report: 120 dB / 118 dB A-weighted SNR referenced to 2 V on low gain, 106 dB / 105 dB on high gain, crosstalk −87 dB (low) and −68 dB (high) at 10 kHz, DC offset under 0.4 mV. atomicbob (SBAF) measured mains-related noise 20 dB below audibility for common headphone sensitivities and could not hear hum, buzz or hiss on a 16-ohm S12 IEM even on high gain.

vs. listeners — The bench says the amp itself is quiet on either setting; the complaints come from the 14 dB of extra gain amplifying whatever a given tube contributes, plus the Alps pot's channel imbalance at the bottom of its travel with very sensitive IEMs. Owners who hummed usually fixed it by changing the tube, dropping to low gain or moving a cable away from the power brick.

Where it splits

What to keep in mind 6

A read of where the reviews land as of September 2026. The Vali 3 has been on sale since March 2024, and almost everything written about it comes from long forum threads and owner posts — there are only two full magazine-style reviews, so the loudest voices are enthusiasts who roll tubes.
The bench numbers here are Schiit's own Audio Precision report for one representative unit, which is candid but is still the maker's, plus an experienced forum member's sweeps. No independent lab has published a full suite, and Schiit's report only uses a 300-ohm load.
What it sounds like depends on the gain switch, the tube and the headphones as much as on the amp. Low gain into a 300-ohm Sennheiser and high gain into a 16-ohm planar IEM are close to two different amps, and the reviewers quoted here were rarely on the same settings or the same tube.
Tube rolling changes the picture for some listeners and not others. Impressions of the stock 6N3P are the baseline; the warmer or more open sound some owners describe came from GE, RCA, Western Electric or Soviet -DR tubes that are not what ships in the box.
Owner star ratings skew positive, since they mostly come from people who chose to buy it, and the Amazon sample is small. The reliability reports here are a handful of posts against tens of thousands of units and should be read that way — as things that can happen, not things that usually do.
Prices move: $149/$159 direct from Schiit at the time of writing, more on Amazon and much more once shipping, tax and a few tubes are added outside the US.
