Limited Edition

Celebrating Audionet’s legendary integrated amp’s 20 years anniversary we present the best SAM ever: the strictly limited SPECIAL EDITION SAM 20 SE (20th Anniversary).

A milestone in German amplifier construction:

  • New MOSFET power transistors with extremely low series resistance for a higher and more detailed fidelity in transient response (as used in the new worldwide benchmark WATT).
  • Extremely potent and acutely fast power supply, guaranteed by an encapsulated and cast-in 700 VA toroid transformer and new extremely low impedance and exceedingly fast audio-grade main capacitors with a 25% higher capacitance of 15,000 μF instead of 12,000 μF as before (total sum of 120,000 μF instead of 96,000 μF).
  • Further optimized inner wiring, all signal cables are made of silver and gold providing highest resolution and finest details.
  • New high grade mica capacitors in all places with crucial affect on sound. Their natural materials ensure a unique neutrality of sound.
  • Engraved front panel and re-designed back panel.
  • Dedicated SAM 20 SE Audionet metal remote control.
  • Inbuilt Phono card with the following improvements:
    • New integrated OpAmps of highest grade with extremely low-noise and fast FET inputs.
    • Optimized mica capacitors throughout. Their natural materials ensure a unique neutrality of sound.

High quality front panels and colored displays

Audionet’s components have front panels made of brushed aluminium. The aluminium is melted by our specifications in a small smelter. It’s exquisite composition is free from old aluminium shares and has an extraordinary surface structure with a very pure color. The rough bodies are finished by hand in traditional craftmanship after the mechanical manufacturing in mordern CNC machining centres. The front panel’s are stained and anodized in the finishing process by our specialists in an artful process.



You have the choice: the front panel’s of all Audionet components are available either in black anodized finish with light grey printing or in silver anodized (natural) finish with black printing.

Machines with displays have the choice between blue or red color. On those with light-emitting diode’s, the LED color can as well be chosen between blue or red.

Press comments on the predecessors


“SAM alone is the best integrated I’ve heard so far.”



“The SAM G2 ist the full monty – a total audiophile heavyweight beyond all price categories.”


Olaf Sturm, hifi&records/

“New SAM G2 defines his class for sure…dynamics, spatial abilities and a level of musicality far above his price point…Audionet SAM G2 hereby gets the most important badge of honour: Reference for integrated amplifiers!”


Video, Domácí, Kino Czech Republic

“The integrated amplifier Audionet SAM G2 is a consequently build analogue hifi-amplifier, with contemporary design and a perfect sound reproduction.

Sound: 100%
Configuration: 95%
Handling: 95% Germany

“Exceptional strength and generosity in all areas are paired with exceptional definition and subtlety. When playing challenging music, the SAM G2 makes an almost Olympian impression. […] Audionet’s SAM G2 is true audiophile bargain. […] one day it will become a classic”


What HiFi England

“This is an impressing product, one of the best constructed amplifiers we have ever seen. […] Only few rivals can reproduce deep frequencies with such control and resolution. […] it is the articulation and the rapidness, that points out the SAM in this section. […] Audionet’s SAM is a deeply impressing main amplifier.”


Audioart Taiwan

“Best recommended.”


Av Extreme Greece

“A state-of-the-art amplifier. […] It is really unique.”


Audiophile Germany



HiFi Choice England

“The projected image is velvet-gloved power.”

Image HiFi Germany

“The truth must be told: SAM is the best main amplifier I have ever heard. I admire most the rare combination of unlimited information flow and the missing of any kind of wiryness. Using SAM, music is more than the sum of all music parts.”


HiFi Video Test Netherlands

“[…] a buy for a whole life!”


HiFi Test Germany

“What is High End? When the neckhair stands on end when listening to music and when even after hours of listening no considerable criticism can be found? Or when you find yourself sitting appreciative on a chair and playing nearly the whole stock of test CDs? […] However, this all happened to me. Music pleasure at its best.
Result: 1+ Reference class
