Description

In order to improve upon the Hex we stopped looking towards to our secret industrial chip, and implemented our new Transient technology as used in our flagship Pavane.

The Menuet is using the same basic frame as used for the Hex. However to avoid internal vibration the electronics are built on a well damped sub chassis.
The Menuet is using four Transient™ R2R ladder modules as used in the Pavane. These modules can handle extreme high sampling rates but are limited to current industry standards which has its maximum (384kHz) on the USB input. Like the Pavane digital data will be split over two 12 bit clusters. Each dac cluster processes a portion of the data in the most linear region of the dac chips and as a result a full 24 bits range in the analog domain will be realized. Despite the single board design, channel separation is close to a dual mono operation. This contributes to the flawless positioning of instruments. The result of this process is an extremely fast and accurate behavior and brings listening experience on a higher level.

In short, the Menuet is a DAC that has taken all the lessons and experiences that her designer has learned over the years, and combined them in an ambitious DAC that can fit in every system. It is musical, honours the Non-oversampling principle while simultaneously incorporating the technological progress that has been made over the years.

Metrum Acoustic at a glance

All Engineering (AE) is a company with a history of innovation in many fields within the world of electronic design. In the audio industry AE is primarily known today for its brand Metrum Acoustics. In the electrostatic speaker field their experience dates back to 1989 and gradually over time broader electronic applications have evolved. 

A diverse range of acoustic system products have been created during this period, always relying on sound electronic design principles. Digital signal processing has played a significant role in more recent developments. 

In hi fidelity audio AE’s attention was initially drawn to the limited availability of certain componentry. Established manufacturers supplying these key components decide how signals should be processed. No alternatives are available and therefore this greatly influences the sound image that is realised.  

Current trends among manufacturers are to use the technique of ‘oversampling’ or ‘upsampling’ within the digital to analogue chipset itself. This forces designers to utilise this method of signal conversion for their own products. It also means that many brand systems use the same building blocks and consequently sound the same. The sound images created by such systems can actually betray the componentry that has been implemented.

These sampling techniques were introduced to fulfil the need ‘to smooth’ the conversion process from digital to analogue and prevent phase distortion. Particularly during the years following the introduction of CD replay, conversion methods proved insufficient with regard to sonic artefacts. In response strong filtering methods were employed and the oversampling technique was born. These techniques however had disadvantages which manifest themselves for example in areas of transient response.

Today there is a growing view that ‘non oversampling’ or NOS for short, offers many benefits but without the compromises mentioned above. AE dedicated considerable time and attention to researching the NOS premise and found its audible benefits valid up to a certain point. 

The question then remained how to remove these sonic artefacts without resorting to oversampling. This question was answered by the first product  made by AE  the NOS mini DAC  Quad, a digital to analogue converter designed and manufactured with modern high speed industrial grade chipsets,  free from most of the disadvantages of the past.  These techniques are improved over time and used over the entire range of products. The most important result is the  sound, which was never so close to the analog origin.
