Rogue Audio Sphinx v3 Integrated Amplifier
Dynamic, transparent, and profoundly musical, this integrated amplifier sets a new standard in affordable integrated amplifiers. Utilizing sophisticated circuitry borrowed from our most advanced designs, it is able to outperform separates costing far more than this single box design.
With 100 watts of hybrid power, this integrated is capable of realistic volume levels that will rival the clarity and presence of the original performance.
The device contains a discrete MOSFET headphone amplifier capable of driving even the most demanding headphones. An excellent user adjustable phono with 44/60dB of gain will accommodate your favorite MM or MC cartridge.
Active and fixed outputs allow for the addition of a subwoofer or other outboard devices, and the active output is driven by the tubes for the best possible sound.
A high capacity linear power supply provides tremendous energy storage to recreate the deepest bass passages while various regulated power supply stages provide ultra smooth sound in the midrange and treble.
The machined aluminum faceplate is available in either black or silver to compliment the rest of your components and the optional remote further adds the convenience of remote volume operation.

The hybrid tube/Class D voicing gives the Sphinx v3 lively drive, a quiet background, and a presentation that feels open yet controlled. Dagogo, Part Time Audiophile, and Part Time Audiophile all highlight its strong resolution, rich midrange texture, and punchy bass, while the flexible phono stage and headphone output make it a genuinely complete integrated.
What Reviewers Are Saying
Pros

Provides a rich feature set, including a phono stage, headphone amp, balance control, and preamp outputs.
Feels solidly built and well finished for the price, without seeming flimsy or cheap.
&
Cons
Can sound a little bright on digital recordings, especially near the top end.
Not the most luxurious-looking amplifier, with styling that some reviewers found a bit dated or industrial.
Its biggest demands show up with low-sensitivity speakers, where more power can unlock a larger presentation.
SOUND QUALITY PERFORMANCE 91/100
Reviewers consistently describe the Sphinx v3 as open, detailed, and musically engaging, with a clear step up in resolution from earlier versions. It is also praised for strong drive, convincing scale, and a vivid, well-organized presentation that keeps instruments and voices lively and natural.
Transparency Resolution
92/100
Reviewers repeatedly call out improved resolution, more detail and air, and a quiet background that lets low-level information through cleanly. One review says it was 'precise and revealing,' while another notes that 'nothing was hidden under the bushel barrel.'
Tonal Balance Musicality
90/100
The tonal character is described as musical, open, and natural, with rich textures and authentic midrange tone. There is a touch of tube warmth and sparkle, though one review notes the treble can ride close to the edge of brightness on digital recordings.
Dynamics
92/100
Dynamics are a major strength, with repeated praise for punch, slam, and the ability to stay composed at higher levels. Reviewers describe it as not running out of gas, delivering 'dynamic slam and full range attack,' and sounding more dynamic than earlier versions.
Soundstage Imaging
89/100
Imaging and space are very good, with width, depth, and dimensionality repeatedly mentioned. One review calls the soundstage 'excellent,' while another says the presentation is wider and deeper than before, though it is not singled out as the absolute deepest or most holographic amplifier heard.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
88/100
Reviewers repeatedly describe the amp as solidly built, with very nice fit and finish for the price and chassis work that does not feel cheap or flimsy. It is not presented as a luxury showpiece, but the construction is consistently regarded as robust and reassuring.
Features Connectivity
91/100
This is a notably well-equipped integrated amplifier, with three line inputs, a phono stage, headphone output, balance control, fixed and variable outputs, and optional remote control. Reviewers also highlight its usefulness with turntables, subwoofers, and external amplification, making it especially flexible for the category.
Value for Money
95/100
The reviews are strongly enthusiastic about value, calling it a bargain, saying it punches way out of its weight class, and even suggesting it is worth it at twice the price. Compared with much pricier amplifiers, reviewers repeatedly frame it as delivering far more performance and flexibility than its asking price suggests.
