Welcome to our August Newsletter.

Just one item this month: an exceptionally good review of our Emperor integrated amplifier, written by leading German reviewer Andreas Gunther, for the online magazine LowBeats.

“The German Physiks Emperor Test

An Imperial class integrated amplifier”

This review was originally written in German.  LowBeats has kindly allowed us to use translated quotes from their review.

The German Physiks Emperor integrated amplifier takes the electronics from the Emperor preamplifier and Emperor stereo power amplifier and packages them into one large chassis:  47cm W x 24cm H x 47cm D weighing 60kg  (19.6” W x 9.6” H x 19.6” D and 132lbs).  Andreas appropriately describes this as a “mountain”.

"We are in the world of Rolls Royce ..."

Andreas was immediately struck by the quality of the Emperor’s construction, which he illustrated with the pictures below.

“The integrated amplifier is a massive block made up of a lot of electronics and even more metal. The company logo on the top cover is laser cut.

This level of quality is what draws the fans. We are in the world of Rolls Royce, who, when asked about their drive system only say: appropriate or sufficient. German Physiks only lists the basic numbers. Into eight ohms: 300 watts. Into 4 ohms: 600 watts. Into 2 ohms: well over 1,000 watts.  We are of course talking about figures per channel. This may be regarded as excessive, but it can also be seen as equivalent to the powerful engine that lies at the heart of a thoroughbred racing car.”

Going under the hood

“The top cover alone is a work of art. On the one hand, it is extremely heavy (15kg), while on the other hand, thanks to a clever mix of materials, it is virtually resonance-free. Strongly recommended for imitation by others!”

Removing the outer chassis reveals a heavy steel plate. This serves two purposes. Firstly, it provides a degree of electromagnetic screening and secondly, the size and position of the slots in the plate controls air-flow through the unit to ensure even cooling. Having a more even temperature distribution allows a better balance of the two halves of the balanced circuitry and therefore a lower noise floor. This system, which was designed with help from an engineer who specialises in system cooling techniques, also eliminates the need for a fan, which is noisy and potentially unreliable.

The Emperor integrated amplifier is constructed on two levels. The top level is the stereo power amplifier section and underneath this is the pre-amplifier. Because the images used in the review to show the inside of the unit were cropped, we have replaced them here with similar views of the stereo power amplifier, which, bar the location of a few wires, looks exactly the same from the top.

Back to Andreas. “When thinking how a perfectly constructed product should look, the slightly untidy looking cabling is surprising. According to Müller: “The build of the first models looked very tidy. On these we routed everything via the circuit boards. But shall I tell you something? It didn't sound good.  The current solution with the additional cables is the result of many long, long evenings of listening ... ""

“The engine room of this racing car is located on the lower level of the Emperor. If you look inside, you will find five power transformers. Each individual section has its own power supply: preamplifier-stage, left mono-amplifier, right mono-amplifier, plus the control and display transformers.  This is pleasingly extreme.”

Listening
“It is fantastic.
It is extraordinary.

As a manufacturer you want your product to receive good reviews, but the reaction of Andreas and his colleagues went beyond our wildest dreams and we have had some wild dreams, though fewer now since we cut out eating cheese before going to bed!

Starting with the new album by Fontaines D.C. “This was recently LowBeats album of the week. A Hero's Death exudes a lot of energy. The introduction features one instrument, an electric guitar: undistorted and panned hard right. Then follows a powerful boost in the sound on the left, as the bass comes in. In the centre are the drums, with a visceral bass drum. Everything is tidy, but this is also real killer music for the amplifying electronics. It looks easy, but the bass eats up the power.

Not the slightest bit of a problem for the German Physiks Emperor here. The sheer presence of drive and strength is fascinating. There are good little amplifiers that I love because of their inner harmony, but this unlimited pressure ... I've been re-discovering the fascination of Watt orgies again after a long period of abstinence.  The Emperor can deliver 600 watts into four ohms.  With loudspeakers like the Heco La Diva, you can demolish houses. On the next track, "Love is the Main Thing", Fontaines D.C. are no longer on a leash. This could also be punk from the eighties. Driven, wild, with a real will to destroy. The Emperor took it like a piano finger exercise. I wanted more - the potential of pure power seemed inexhaustible.”

 

Listening to the new edition of Joy Division’s legendary album Closer: 

Gosh, how fresh and up-to-date it sounds. The mix is ​​extremely fat, as there is hardly any breathing space. “The Eternal” is of course my favourite song. The bass dominates. Each melody line is built-up from below. It was wonderful how the German Physiks set out the space. A dark, dark-black background. This is also a great ability.  The contrast with which the music stands out is exceptionally strong and solid. Great values, great art from the Emperor.”

 

“In the last few weeks all our loudspeaker tests have been conducted with the German Physiks Emperor.   Again, and again I got the same impression: “Hey. I haven't heard it sound that good before”.  It was particularly impressive when testing the new Dynaudio Contour 20 (now in the i-version), because we have heard it with practically all the large and expensive amplifier components of the past four years. For direct comparison however, we only had our reference amplifier: the SPL Director Mk2 (preamplifier) ​​and SPL Performer m1000 (mono power amplifier) ​​and the ingenious Westend Audio Monaco tube amplifier.”

 

“The SPL Director preamplifier and Performer power amplifier combination was tonally equal, but - although roughly equally powerful and similarly distortion-free at the highest levels as the German Physiks - it didn't have much to compete with the enormous joy of playing, the rousing power and the really impressive depth representation that the German Physiks Emperor provided. The Westend Audio Monaco kept our attention for a long time. Most members of the different listening groups found its wonderfully fine openness to be at least equal to the German Physiks. But even it had to give way to the very high levels that this incredible force could produce.  What the Emperor shakes out of the transistors, so seemingly effortlessly with dynamic live music (for example David Gilmour Live At Pompeij) is breath-taking. It is fantastic. It is extraordinary.”

In conclusion
“First among equals”

“Somewhat surprisingly, the Emperor, as a newcomer to the amplifier world, was able to effortlessly play its way into the group of absolute top end amplifiers such as Soulution 530, D’Agostino Progression and Westend Audio Monaco. The idea of an exclusively analogue way of working is old-school, but it is also very consistent. Another advantage of the Emperor is its sheer strength, which could even make it the first among equals.”

What more is there to say, other than to offer our sincere thanks to Andreas and his colleagues at LowBeats.
