Frequently Asked Questions

What is the main difference between the AMG STA-SE and the original AMG STA?

The AMG STA-SE brings several significant improvements, including an optimized class D circuit, aerospace-grade precision components, a new negative feedback circuit, and an enhanced power supply. These modifications result in better sound performance, greater accuracy, and increased dynamics.

Is the AMG STA-SE suitable for all types of music?

Yes, the AMG STA-SE is designed to excel with all musical genres. Its wide bandwidth, low distortion, and dynamic capability make it a versatile choice for faithfully reproducing any type of music, from classical to rock, jazz, and electronic.

Is it possible to use the AMG STA-SE in a home theater setup?

Absolutely. Thanks to its ability to operate in bridged mono mode, the AMG STA-SE can be used in a multi-channel configuration for a high-quality home theater system. Multiple units can be combined to power the different channels of a surround system.

This power amplifier makes a very high-quality impression. Sonically, it performs at a very high level. You need to let it warm up for a few days so that it can show its qualities.
I also experimented with several interconnect cables, such as the Linn Black Balanced Interconnect or the Linn Black Unbalanced Interconnect.
Here I had to find that a mixed configuration of the interconnect cables (RCA and XLR on the other side) does not work without interference noise. No matter how I set the rear toggle switch (Bal. - Unbal.). Unfortunately, there is no information about this in the description.
This means that if I prefer an RCA connection, the toggle switch must necessarily be set to unbalanced! Otherwise, the connected speakers may be damaged.
I had not experienced this with any previous amplifiers from Linn, Naim, etc.
Once everything is connected correctly, the power amplifier demonstrates its qualities excellently; the music is transmitted calmly and almost noiselessly. I will get a second power amplifier to hear its qualities in mono operation.
In any case, it drives my "old Linn Isobarik DMS" with stoic power.
I am thrilled.

Diese Endstufe macht einen sehr wertigen Eindruck. Klanglich spielt sie auf einem sehr hohen Niveau. Man muss sie einige Tage warm laufen lassen, damit sie ihre Qualitäten darbieten kann.
Ich habe auch mit einigen Verbindungskabeln experementiert wie dem Linn Black Balanced Interconnect oder dem Linn Black Unbalanced Interconnect.
Hier hatte ich feststellen müssen, dass eine Misch Konfektionierung der Verbindungskabel, (Cinch und anders seitig XLR), nicht ohne Störgeräusche funktioniert. Egal wie ich den hinteren Kippschalter (Bal. - Unbal.) gestellt hatte. Hierzu gibt es leider keine Hinweise in der Beschreibung.
Heisst also, wenn ich eine Cinch Verbindung favorisiere muss der Kippschalter zwangsweise auf unbalanced stehen! Andernfalls können die angeschlossenen Lautsprecher Schaden nehmen.
Das hatte ich mit keinen voran gegangenen Verstärkern wie von Linn, Naim usw. erlebt.
Ist einmal alles richtig angeschlossen spielt die Endstufe ihre Qulitäten vorbildlich aus, ruhig und fast Geräuschlos wird die Musik übertragen. Ich werde mir noch eine zweite Endstufe anschaffen um die Qualitäten im Monobetrieb zu hören.
Jedenfalls treibt sie mit stoischer Kraft meine "alten Linn Isobarik DMS" an.
Ich bin Begeistert.

The sound with RCA was sweet and spacious enough. I wanted to use the RCA for the receiver and XLR in combination with an external DAC. Unfortunately, with me the XLR produced the typical pseudo-balanced sound, very wide with some sharpness, where left and right do not come together properly in the center. The above does not have to be true for someone else. All in all, I did find it one of the best class D amplifiers I have heard.

Het geluid met rca was zoet en ruimtelijk genoeg. Ik wilde de rca voor receiver inzetten en xlr in combinatie met externe dac gebruiken. Helaas gaf xlr bij mij het typische pseudo balanced geluid, heel breed met wat scherpte, waarbij links en rechts niet goed samen komt in het midden. Bovenstaande hoeft voor een ander geen waarheid hoeft te zijn. Al met al vond het wel een van de beste klasse d versterkers die ik heb gehoord.

Excellent product. I own a SHINAI from Grandinote, so I was able to compare both amplifiers on my speakers (Atlantis Lab AT21 pro) with a Wattson MADISON Streamer/DAC/Preamp as the source. Without claiming to match the SHINAI (which is eight times more expensive), this one delivers a rather impressive performance considering its size and technology. There’s substance, nuance, openness without harshness, and depth. It’s more than satisfying and a real pleasure to listen to.

However, the connections at the back are not very practical, as they are quite narrow and close together.
It is also quite sensitive to the power cable.

Excellent produit. Je possède un SHNAI de chez Grandinote j'ai donc pu comparer les deux amplis sur mes enceintes (Atlantis Lab AT21 pro) avec comme source un Streamer/DAC/Préampli Wattson MADISON. Sans prétendre égaler le SHINAI (x8 plus cher) il propose une restitution assez impressionnante au regard de son encombrement et de sa technologie. De la matière, de la nuance, de l'ouverture sans agressivité, de la profondeur. On s'en contente bien volontiers et avec plaisir..
Les connections sont cependant peu pratiques à l'arrière car assez étroites et resserrées.
Il est assez sensible au câble secteur.
