Prepress Ayre KX-R

According to symmetrical connection with the feedback-loop loose Ayre CD player, the Ayre KX-R (19800 euro) spread Rocky-Mountains-esque, spacious soundscapes.

That feedback in various circuits to circumstances unpleasant THD can cause higher-order, is at least since the mathematical models by James Boyk and Gerald Jay Sussman no question ( ~musiclab/feedback-paper-acrobat.pdf). That Hansen prefers simple circuits and symmetrical layout other, nod experienced Highender also like to off.

As well as the fact that screening does not harm where the consequence of a Ayre puts them in amazement. The Westerners in Boulder, Colorado first get a 44 cm wide, 30 cm deep and 10 cm high aluminium ingots for building the Super stage KX-R with Precision milling like a Halloween Pumpkin and gradually to undermine him.

As long as he produced, composed of fine sheet metal core of the transformer with a tenth of a millimetre accurate fit in the recess of the California Mercury Magnetics (“the guitar amp transformer company”) fits in the middle of the Aluklotzes.

So also the amplifier units of the right and left channels reach their two backroom where the holes for six XLR kontakter and four cinch sockets are already provided. The helicopter with the display and the front buttons, as well as with the remote control electronics finally gets his own armored corridor as well as the power suppression air restrictor and the wiring harness that leads to the Ayre-remote-composite jacks on the thick-walled back.

Another example of absolute intransigence: driven by servo-motors, saucers great adjustments, which look as if from a feudal English grandfather clock. Two of these works of art select in the perfectly symmetrical built preamp left and right and for plus and minus four XLR – and four RCA emergency inputs.

Four others vary the level where the spring grinders under clearly audible, appetizing Plopps may hit 60 gold-plated solid silver contacts and directly soldered Extra manufacture precision resistors in decibel levels.

Thereby, the KX-R not like other precursors simply attenuates the input level. The Ayre rather reduces the amplification of the output stages with switching resistors. So she takes in purchase, that there is to digest before relatively high level (what distortion minimally increases the), it suffers from the noise in the already raised signals not so much as with the conventional method. A plug-in fixed resistor sets only the maximum overall gain in the entrance; + 6 or 0 or -6 dB are at issue.

According to the Ayre’scher philosophy, no feedback loop can be found in the k-x-R (in technical language a symmetrical differential amplifier with easy-to-navigate field effect transistors, the on cascade current mirror the output stages drives). Must set up Linearizing ‘s resistance in the wires leading to individual transistors, the extremely picky selection of all components leads to the distortion remains.

Single pole RCA-comers can relatively perfect Symmetry the input differential amp, serious Highender still only symmetrical clamp the KX-R.

The testers in the listening room once enjoyed the heavy metal precursor were confirmed soon that the k-x-R for RCA control a little like playing with the handbrake on, and really only as half thing can be considered. After linientreuer symmetric connection with the feedback-loop loose Ayre CD player CX 7e MP (test 6/09) spread the Ayre – in cooperation with the TEM 3200 Thorens reference Mono blocks (1/06) – then but really completely effortlessly Rocky-Mountains-esque, long-range and virtually infinite in the bass and treble sound landscapes. In all of this a her own countenance; maintained the KX-R It seemed that she would let too much Gezwirbel from the rest.

So reference preamplifier Thorens TEP endeavoured 3800 (5/08) to wrest there is a Little rabbit and there is a lip tremor more on voice richness as a Vienna Deng, where the Ayre – while she gave up actors and instruments with a uniform bright light – more even, remained calm and professional.

Until then a matter of taste, the Thorens at least knew to resist funky Jazz against the beautiful American. By them with drive and piano courses provided bass in perfect marksmanship with verve, the TEP 3200 defended then but their reference dominance.
