Integrated Amplifier, NAD C 375 BEE

For its class, its previous NAD offered sick C 372 of issue 4/04 performance. Can the new NAD sit C 375 (1400 euro) after thorough development in sound and dynamics one?

Elimination amplifier curlicue to the superb sound for the student budget – so NAD began today over 30 years ago with the 3020 C. Even if the C now rather turns 375 BEE at a price of 1400 euros to full-blown assessors, still has a certain simplicity distinguished him.

At least the optional titanium – or graphitgraue front plate, which comes with still no display, but access to the absolutely necessary lenses and knobs. The only concession to modernity: The high level input jack for MP3 player along with corresponding to election tipsters.

The back is then but yet more ambitious. A double set of thick, gold-plated speaker terminals which can accept cable shoes, was not mentioned at times of 3020. Nor by a RS-232 port, which allows you to stop the C 375 if necessary also via PC or home control systems from AMX or Crestron to work.

AHA, at the RCA another is labeled with “MP”, granted preference in the case of the front einsteckens of the Jack. With CD, disc, tuner, aux, and the two tape loops, it remained however in the tried and tested.

As well as with the normally by ironing preamp-off – and amplifier inputs and a Pre-Out, whose level is above a Kleinpoti bridged to until can be lowered to 10 decibels and thus adapted to various additional amplifiers.

As already had a small switch, allows the Aufrüstfall to summarize the two built-in power amplifiers, whereby they can press truly massive 600 Watt in bridged mode. Shall provide the normal power for Wilder party usage, is the soft-clipping function to protect the tweeter of the speakers from too energy-rich clip THD. This applies at least up to mostly night later, in which the first bass chassis intense smell and then makes the straddle.

At the latest when the HiFiist now is in the Interior of the new amplifier well more bringing three kilograms C 372 compared to the already arch-powerful predecessor on the scale, then a “Golly” departs him. Such a gigantic, protected by a thick-walled shield toroidal power transformers and so extra mournfully staring Elkoflaschen found only in much more expensive amplifiers. Especially since the NAD can use its energy supplies thanks to the power-drive arrangement even more voltage – and times more current stresses, so particularly intelligent (see post “stereoplay – know-how: shut up”).

Despite their variety, the 16 strong silicon transistors on the power amp boards are far left and far right probably hardly ever suffer from deficiency. And the semiconductors in the prepress Department at high quiescent current in two screen off Thermo containers called “class A gain modules” sweat, certainly not. Because they be in the NAD more generous way by own Trafowickeln, rectifiers and capacitors. The module that sits in the input selector relay Bank, strengthen the music signals and points to the volume potentiometer further. Under the scheme it takes the second then again supports by the hand, and then the left and the right stream to even their amplifier page.

That it is NAD here not only to the sheer strength gains, clarifies the reference to a “distortion canceling unit”. The exact effect of the company and the developer reveals no details Björn Eric Edvardson unfortunately. Maybe regulates the C from 375 any distortions not only with passive feedback circuits, but puts them in addition with extra reinforced correction signals to the body. As well as always, old clanking history diagrams like the new measurement, which takes into account reactions of the boxes, the NAD expelled themselves as relatively more zealous regulators.

In the listening test succeeded first of all, to indicate their limits to a whole series of smaller amplifier. The first immediately voice was More paucous, round, More welcoming Creek Evo 2 (4/09, 43 points) at “So together” of the group Tri Sandie wool aschs something – while the young lady via NAD had a slimmer and more or less with combed back hair of a little dispassionate, brighter and more stringent. Soon that the electric bass now but would swell, was given the smaller Briton soon shaky knee and appeared mushy; C 375, however, brought out with joy to big, elastic bold and sporty accurate steps.

And while even a more robust journeyman like the Vincent SV 121 (10/05) before that great respect, the NAD in Kari Bremnes sound landscapes such as from the CD “Over En” felt contented. Deep fjords and is mounting high mountains, wide, of percussions light lit horizons and an absolutely stable pictured, masterfully directing singer in the Middle – during such exercises, the NAD developed Championship.

With like, he attacked the best reputation Marantz PM 15 S 1, which however prevented an overtaking with his warmer lower mids. The muscular fresh NAD was homogeneous and More agile but. Those looking for the absolute blast so for affordable money, takes the athletes clearly C 375.

Normal amplifiers, the developer must decide: I interpret him more for power-hungry boxes or more for power drunk? With the power drive system NAD aims to at once both. This includes the current is measured at the output of the amplifier constantly. He remains in the frame, the switch of power transistors (1) an of the Trafowickel (2) and the diodes by direct (3) included higher voltage.

It is risky, open the switch, according to which via (5) a wrap (4) with thicker wire comes into play, the less stress, can dispose of it much more power. For a time of the Memory cos (6) transhipment much thrust remains but also in terms of voltage.
