L'un des intégrés les plus neutres que j'ai pu écouter est l'ASR Emitter 1 en version Exclusive, le prix est de 10990 € ttc en France.
La fiche technique est la suivante mais je ne vois vraiment pas en quoi elle peut déterminer la neutralité du produit :
The technique of the ASR Emitter I :
• two channel amplifier in the acrylic casing with input selector and volume control.
• Class A/B technology with 12 Toshiba special Audio-MOSFETS with high impulse capacity.
• Mounting bars of the output Transistors made from massive brass for low resonance.
• Volume control with relay attenuator in 1dB-Steps with balance and input level adjustment.
• 25 mm LED-Display available in yellow or blue as operational indicator, adjustable in many
• 6 high-level-inputs switched with relay, plus 1 direct input, 1 record output.
• Gold plated massive brass RCA-sockets with Teflon isolation. Massive silver-wires for all
• large 60 amperes binding post for cable-shoes and 4 mm banana-plugs.
• 1 plug in slot for Phono – pre amplifier circuit board or balanced input.
• Protection-circuits against overload, Clipping, Short-circuit, Overheating and DC Offset.
• Circuit board with especially strong copper, parts of the two channels in mirror-symmetrical
• External power supply with 3 PM transformers and energy-management, separate rectification
for each of the 8 voltages with 32 Schottky rectifiers.
• Especially stable power supply casing of high-quality, very stable steel sheet metal.
• Low loss Neozed high load fuse built in the power supply unit.
• stable industrial power connector from Harting for the connection to the amplifier-part.
• Double shielded connection cable to the amplifier-part 2m long, on wish other lengths.
• Power cable ASR Magic cord 150 cm with low loss 21A power connector at the power supply.
• high-quality ASR design remote control made from Corian for all functions.
Additionally equipment of the ASR Emitter I Exclusive
• Military ceramic input IC AD 843 SQ, buffering capacitors with total 570.000 uF.
• Balanced input for CD with switchable input impedance.
• feets made from of massive brass for the amplifier unit available in chrome or gold.
• Power supply with improved equipment for higher performance. The 3 PM Transformators
equipped with higher magnetic flux kernel-sheet metal, rectification with 56 Schottky rectifiers.
• A battery power supply for the input stage with 400.000 uF additional Buffer available as an
Data for both Emitters :
