2 x 3 = 6

Based on our Method 3 Class A Monoblock Amplifiers we proudly present the Method 6 Stereo Amplifier.
Using the award winning Infigo Low Temperature Class A circuitry this amplifier does not run hot, despite being in a smaller enclosure.
Just like it's bigger brothers, it has a DCBA controller to deliver very controlled, powerful bass with no low frequency roll off.

Low Temperature Class A

Low Temperature Class A is notable for the elimination of cross-over distortion, with ultra-fast transient response. Thanks to this development, sonics remain impactful, crisp, and clear, while the amplifier stays cool to the touch. Over time, Low Temperature Class A's lower operating temperature maximizes the life of the amplifier.

DCBA

A highlight of Infigo Audio amplifiers is the company's DCBA™ system.
DCBA™, or DC Bias Adjustment, balances output DC level without limiting low frequency output.
Bass response is tight, powerful, with elimination of phase distortion at lower frequencies thanks to the removal of capacitors in the audio path. The low frequency range extends down to 0 Hz, with a separate protection circuit that disconnects the speakers when the DC level in the signal reaches too high a level.

Aesthetics

The Method 6 comes in silver or black front and top panel, the heatsinks and back panel are in black aluminum.
The custom milled heatsinks from solid blocks of aluminum are curved, not only for aesthetics but also to avoid any mechanical resonances.
And, like all Infigo electronics, the solid top is removable, affording a view of the internal circuitry that is protected by a transparent cover.

Infigo Audio Method 6 — compact Class A power with expansive musicality

The Method 6 distills Infigo's larger Method ethos into a single-box 2x100W Class A stereo amplifier that impresses with an open soundstage, precise imaging and an unusually detailed, involving midrange. Karl Sigman highlights its tight, powerful bass—helped by the proprietary DCBA bias system and very low output impedance—and notes strong transient grip and headroom for its class. The glass-top chassis, careful thermal design and selectable standby modes combine high-end aesthetics with practical engineering. Ideal for listeners who want transparent, expressive playback with demanding speakers, the Method 6 is also positioned as a convincing value in its peer group. Early reviews (see Audiophilepure) recommend it for those seeking refinement without running monoblocks.

Audiophilia

"it offered that same unique quality in sound that the Method 3 had originally conveyed but at less than half the price."

Pros

Large, well-defined soundstage and superb imaging that reveal delicate timbral detail.
Tight, powerful and controlled bass supported by the DCBA bias system and low output impedance.
High-quality build and distinctive styling (glass top, cooling design) that combine aesthetics with practical thermal management.
Strong-value proposition among high-end options—delivers much of the Method-series character in a more compact, single-chassis package.

Cons

Front-panel mode LED blinks in standby modes and can be a minor nuisance in low-light listening rooms.
Slightly less absolute clarity and peak power than high-end monoblocks—excellent for most systems but not a direct replacement for the very top reference monoblocks.

Dynamics

90/100

The Class A 2x100W design combined with a very high damping factor (550) and low output impedance (~14 mΩ) delivers authoritative, well-controlled bass and excellent transient grip as noted by the reviewer. Karl Sigman specifically praised the Method 6 for supporting "powerful and controlled bass" and for its headroom/low-frequency extension (down to 0 Hz), indicating strong current delivery and speaker control for its power class. Given the medium-power Class A topology and explicit praise for bass authority and control, a high dynamics score is warranted.

Soundstage Imaging

91/100

The Method 6 is reported to produce a large soundstage with "superb imaging" and excellent clarity, with delicate details blossoming and stable imaging. The reviewer singled out piano and the system pairing as particularly impressive, suggesting strong channel separation and spatial definition. These comments support a top-tier imaging score for its class.

Build Quality

89/100

Physically the unit is described as elegant and unique with a clear glass top and calming blue lighting; internally it uses a robust power approach (low-temp Class A and a proprietary DCBA system) that keeps temperatures modest while delivering high performance. Thermal management is noted as good (warm but not burning hot), though the reviewer found the front-panel blinking-mode light slightly annoying — a minor ergonomic quibble rather than a build flaw. Overall construction, power-supply design and thermal approach suggest high build quality for a stereo Class A amp.

Value for Money

90/100

The reviewer explicitly states that, although expensive, he "very highly recommend[s] it if you can afford it," and cites a $20,000 price relative to $55,000 for comparable monoblocks, arguing the Method 6 is "arguably equally good sounding" for much less. That language supports a justified-premium assessment: it is a high-end product but reviewers felt it delivers performance commensurate with its asking price in its competitive context.
