Probably no French city as much high-tech such as in Toulouse focuses on the edge of the Pyrenees. The home of audio Aero prima CD.

Only 34000 people work no wonder here in the aviation industry -, that the audio Aero company founded ten years ago, already contains the aviation on behalf of. Suitable to the tube hybrid integrated amplifier prima, the French offer also a CD of same name.
Tubes can beguile
As in the amplifier, which convinced with a charming and unusual combination of tubes before and IC power amplifier section, is also in the player old-fashioned glass next to modern Silicon: two miniature dual triode of type JAN 6021 W act as intermediaries between the D/A converter (PCM 1739 by Texas instruments) and the output jacks. Despite the relatively exotic construction behaved the prima in the measuring laboratory TESTfactory completely unobtrusive: 2.1 volts of output voltage are standard, 100 ohms output impedance to prolonged or high capacity cables uncritically, the error correction of the Sony drive is top notch. Also the sampling rate converter, with which the audio Aero extrapolates from the CD data from 44 to 192 kilohertz sampling rate, does what it should: it reduces jitter on very ordinary 178 picoseconds. The Digital pulse edges Tatterich belongs to the main enemies of sound in digital systems. The upsampling to 192 kHz requires a complete Reclocking; because of the odd ratio of this frequency to the original CD clock This is to prevent that the error of time – shift instead to disappear – only to higher frequencies.
Of course, the tubes leave its signature in the output signal: compared to transistor output stages, the instruments showed slightly higher, but beautiful “natural” staggered THD harmonics; This is probably desirable as part of the vote. Wear or Kinky practice properties – problems like associated with tube – you must to worry here, by the way: the JAN 6021 was originally built for the military and for tube conditions extremely shock – and vibration-proof. “Microphones” is also for them a foreign Word, “Aging”: she should withstand 16000 hours according to the Philips data sheet (from 1961).
Le “Sound of Toulouse”
In the listening test provoked the French player energetic foot rocker, as well as irritated frown, depending on the selection of music and listeners – and also the same handset from CD to CD could change his mind. Blues and rock fans at least may to give the audio Aero for his talent, even recording technically substandard productions much heart and Groove. It was an amazing match: already the Aero neighbors Helios and Kora in previous tests showed this fiery exuberant sound – it seems so clearly to give a “sound of Toulouse”.
What was a pleasant intensity kick with “electric” disks, could be too much of a good acoustic recordings, particularly with classic repertoire. Had you heard a great player before, the Allegri String Quartet via audio Aero almost too much pressure put on the sheets, guest clarinetist James Campbell schalmeite markedly tart as the testers know that by this very natural unspectacular record (Naim recordings). Although those not quite neutral vote a few points will cost the Aero – in a suitable environment he can make music devastatingly good.
