Pros
Combines Class-A/SET-like tonal ease and textured midrange with exceptionally fast, clean GaN transient response.
Delivers expansive, immersive soundstaging alongside powerful theatrical dynamics and ample headroom.
Stable output drove every speaker in the reviewer’s collection with ease, while 400W bridged operation provides an upgrade path.
Highly efficient, compact, cool-running design is paired with notably refined industrial design and finishing.
Cons
Listeners seeking extreme power reserves may need a second unit in bridged or bi-amp configuration.
Its slightly laid-back, SET/Class-A-style voicing may feel less visceral than some listeners prefer.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 94/100
Reviewers describe an unusually immediate, clean and natural presentation, combining tube-like musical ease with the speed and control expected from advanced GaN switching. The Tempo is especially praised for its powerful transient delivery, high resolution and room-filling spatial presentation.
Transparency Resolution
94/100
Audiophilepure found resolution “as sharp as electrostatic speakers” through the midrange and treble, with that clarity maintained into the low bass. Future Audiophile likewise heard instruments as clear, honest and seamless, while describing textured vocal reproduction.
Tonal Balance Musicality
93/100
Future Audiophile calls the Tempo stable and linear, yet says it sounds like a Class-A or SET amplifier rather than a stereotypically clinical switching design. Audiophilepure heard immediacy and presence without audible irritation, and Future Audiophile noted Cassandra Wilson’s dark, deep and richly textured voice.
Dynamics
96/100
Dynamics are a major strength. Audiophilepure says the amplifier’s dynamic ability can “define the charts,” while Future Audiophile reports hair-raising theatrical swings, ample headroom and effortless operation with every speaker in the reviewer’s collection.
Soundstage Imaging
93/100
Future Audiophile reports that well-recorded music was thrown into the room in every dimension, even seeming to extend behind the listener. The same review describes a breathtaking soundscape in which individual instrumental lines remained clear and communicative.

Build Quality
91/100
The compact, high-efficiency design combines 200W per channel into 4 ohms with a 400W bridged option, ultra-high-frequency 800kHz switching and a stated robust power supply. Future Audiophile praises the industrial design and attention to detail, while the supplied Pelican case, quality power cord and accessories reinforce the carefully finished presentation.
Value for Money
95/100
At the reviewed $5,500 price, Future Audiophile calls the Tempo a “totally game-changing event” and compares its performance favorably with far more expensive, power-hungry Class-A amplifiers. The reviewer also found it capable of driving a very broad range of speakers while consuming little power and producing barely any heat.

Manufacturer's Description — AGD Production
Design Philosophy
The AGD “TEMPO” Stereo Amplifier is the new addition to our state-of-the-art Hi-End Power Amplifiers family. TEMPO is our first compact Stereo Amplifier utilizing the same unique technology of Gallium Nitride Power-Stage design already in use with all its Hi-End AGD siblings.
The AGD “TEMPO” is rated 200+200W 4Ohm (100W+100W 8Ohm)
To achieve these performances in such compact CNC machined cabinet, we have designed a new GaN- based output power stage with a new mother board that contains the low noise power supply and all the analog buffer stages, small enough to enable these outstanding minimalistic footprint.
As for all AGD amps, the GaN-based power stage module utilized in the AGD TEMPO is fully upgradable to next generation modules using future generation of GaN devices with improved technology so to maintain the full value of the product in time.
The AGD TEMPO Stereo Amplifier uses the same fundamental technology pioneered with the AGD Vivace, the first Hi-End amplifier based on Gallium Nitride power MOSFET, the AGD THE AUDION, and The AGD GRAN VIVACE.
Moreover, the new integrated GaN-Sound module design can operate also in bridge mode delivering in this configuration twice the nominal stereo output power, so about 400W on 4ohm, with a maximum peak current capability of 30A.
The NEW GaN-Power output stage can efficiently switch at much higher slew rates than any silicon-based counterparts and can deliver the most sublime sound thanks to their ideal “by the book” oscillations-free switching capabilities.
The New AGD GaN-Power Module
Thanks to a world-class PCB design, a refined selection of top-quality audio grade components, and the extremely efficient GaN-based power stage we achieved the design’s goal to operate this integrated Stereo Version of at ~800kHz as standard PWM frequency.
This operational frequency of the PWM controller is the same one used with the GanTube88KT and GaNTube120KT.
The higher PWM frequency operation delivers a direct and positive impact on the overall outstanding sonic and musical performances with sublime mid-high range realism along with the unique tight and controlled bass register.
Hence, the TEMPO maintains the same distinctive tonality that charactarizes all our designs, The Audion the Vivace and the top of the line the Gran Vivace.
The New AGD TEMPO Cabinet
Front
- Single billet CNC-machined cabinet delivers the best solidity and compactness for audiophiles that are looking to get the superior sound with the most advanced technology on the market today and to “down-size” the footprint of regular amps at the same time.
- Available in SilverBlack and mirror-polished finishing (the latter custom order only).
Back
- The AGD “TEMPO” back panel configuration is perfectly symmetrical and offers easy access to both the single ended and Balanced inputs connectors. The inputs (completely independent) are selectable via toggle switch.
- A stereo-bridge switch enables the operation of the Stereo amplifier in bridge mode as 400W monoblock power stage (input signal via the right channel).
- Two sets of super rugged solid copper binding posts, specially designed by AGD, and the connections for remote trigger input and output complete the back panel configuration.
