The new C370 was amazing, it was mainly designed to function as a cheap centerpiece of a quality component system, but due to the amazing technology put into it, it had raised the price to $749 to $699, which is costly for some people. This integrated amplifier is absolutely worth it for the price due to the fact that it has a mass of features, including the main thing itself, the remote controlled integrated amplifier. This amplifier has increased most of its specs compared to their last product, the 317, and now it has an increased 120Wpc, which in effect increased the number of line inputs to 7. And this in effect, has made this amplifier, a trumped up version from before, obviously making it much more better. If you were to see a picture of the c370, towards the left of the black panel at the front, there features your default headphone jack, along with an abundance of tiny buttons, which is then complimented by the gentle green illumination, which makes it look really good, as well as it used to indicate various source modes and functions, and on the right, they feature various elements, one of which being the non intrusive collection of the classic treble and bass controls, as well as the original balance control, and to adjust the volume, they also provide you with the volume pot. Although, the amplifier features many things, the real question we must ask is does it do what it was made to do, the answer is yes, it amplifies sound like no other, and the dynamics are much better and clearer, making it a must have device.
The new C370 was designed to function as the cost-effective centerpiece of a quality component system. This full-featured, remote-controlled integrated amplifier offers a multiplicity of performance features, and the flexibility to evolve as your system grows. Compared with the earlier 317, NAD has therefore upped the 8-ohm power from 80Wpc to the C370's 120Wpc, increased the number of line inputs to seven (plus two tape in/outs with dubbing capabilities), and lowered the price from $749 to $699.
From the far left on the black front panel are a headphone jack and a number of tiny buttons with green illumination to indicate source modes and functions; on the right are a non-intrusive set of treble and bass controls (±6dB at 100Hz and 10kHz, with a tone defeat switch), a balance control, and an illuminated, motorized volume pot.
On the rear panel are a large bank of RCA inputs, two sets of speaker outs, an NAD link (for remote control of associated NAD gear), a 12V trigger out (for remote activation of ancillary equipment also equipped with a 12V trigger), a hardwired power cord, and a single switched AC outlet. The most interesting features on the C370's rear are the pre-out/main-in sockets (normally linked with jumpers), which allow one to employ an external preamp or power amp. An additional pre-out section with its own volume control offers attenuation of the output level from 0 to 12dB, for gain matching with another power amp. Finally, Soft Clipping and bridge-mode switches correspond to illuminated indicators on the front panel.
Soft Clipping, a trademarked NAD circuit, allows users to maximize gain and dynamics when driving the C370 extra-hard, the tradeoff being enhanced headroom Bridging the C370 in mono lets you drive a single loudspeaker with roughly 300W into 8 ohms, while pre-out 2 allows the addition of a second power amp (such as the precisely gain-matched NAD C270, which duplicates the C370's power section) in bridged mode or as part of a horizontal biamp configuration. As with the VTL combo of IT-85 integrated and ST-85 power amp I reviewed last February, the flexibility of adding a second amp (the C270 costs $599) means that the C370 won't suddenly become obsolete if you decide to upgrade speakers or move to a bigger room. A nice touch.
Among the C370's more intriguing new design features are its Impedance Sensing Circuit, or ISC (patent pending), for its power-amp section. "This automatically adjusts the power supply of the C370 for maximum voltage or maximum current, depending on the speaker load seen by the output stage," explained Greg Stidsen, NAD's director of product planning. "Most moderately priced electronics run out of current early when presented with less than 8 ohms speaker impedance. They look good on the spec sheet, but they've got no balls. The C370 offers 120W continuous power into 8 or 4 ohms. But music demands short bursts of power, not a continuous drone. This is where the ISC gets interesting: IHF dynamic power (10ms toneburst) is 210W into 8 ohms, 340W into 4 ohms, and 450W into 2 ohms.
"The power supply of the C370 features a nice, big toroidal transformer, and the signal path employs very short signal routing, aided by switching inputs via relays (rather than sound-coloring CMOS transistors) and star grounding for lowest possible noise. Speaker switching is also via relay, which has the nice convenience benefit of activation via IR remote. We use lots of premium-quality parts—like 1% metal-film resistors and 2% film capacitors—where they make a difference in sound. The preamp and power-amp driver stages use NAD's own discrete class-A amplifier modules—high-current, low-impedance gain devices that contribute significantly to the excellent sound quality."
I figured it was about time I payed back AudioReview.com with some feed back on this integrated Amp. I have a pair of PSB Status Golds and was using a Marrantz 2375 receiver which puts out 125 watts of power. Sounds real "juicy" with any speaker but the problem was power....in the form of amperage,I believe, when the ohms drop on these speakers. What would happen at times of high loading there was an audible pop....this I think is overloading the amp, or clipping the amp as the speakers can really give out some very good sounds.Any way someone said the NAD was a high amperage model and could handle the PSB's. I bought the NAD C370 and upon hooking it up I selected the same CD's that brought out the popping noises on high volume levels with the Marrantz. I let it blast and....no popping....also noted there was much more punch I hadn't heard from the Marrantz. Boosted up the power beyond the levels where the popping was evident with the Marrantz and just got very clean loud music. The bass is way more solid and over all mid's and highs are about the same....which is real good as I like the 2375 lots and have it hooked in my bedroom. It has been a great performer and was revieved in Audiophile magazine, they concluded it's a winner....especially for the price/performance. No frills....just great sound with lots of muscle. Also has a balance knob that some of the high end receiver/amp's don't have which is nice when I sit off axis from the speakers. Highly recomended.

This is such a good piece of kit . I am going to provide a review on the NAD C370 Amplifier .It has oodles of power to efforlessly drive your speakers without even breaking a sweat, but still retains a more softer, delicate side. So as its churning out the bass, the amp doesn't lose any of the musics detail.thanks you
This is such a good piece of kit. I bought it last year and it has been going strong ever since. The sound quality is amazing and it was quite a reasonable price to be honest. It is very sturdy and durable and I would recommend it to anyone. It was prompt delivery as well. Like othe rpeople, I've had mp3 speakers but I wanted something to increase my music-listening and this was perfect!
I am going to provide a review on the NAD C370 Amplifier. As a music lover I have used standard devices such as ipod speakers and mp3 speakers. However I wanted to up my game and heighten my musical experience. I decided to get the NAD C370 because of its multiple performance issues and its good midrange.
The good points about the NAD C370 were that I could play different genres of music and they didn’t sound overpowering or weak. There was a balance in the music. When listening to female artists such as Rihanna or Emelie Sande I did not need to lower the volume or change the setting to a background level. These 2 artists have completely different styles of music and I thought that the sounds were rich and engaging. However when listening to male artists such as Justin Timberlake or Pharrell Williams the vocals were resonant and full bodied. I found this to be interesting especially when both of these guys would reach a high note.
However I found that when I listened to relaxing low classical pieces an example being Debussy’s Clair de lune. Although I could still hear the beauty of the music, there was lack of emotion. This was disappointing as I thought that the Classical pieces weren’t given the justice they deserved.
The NAD C370 Amplifier has pros and cons like any other amplifier would however I think it is good value for money and offers what it is meant to offer i.e. performance and emotion.

Ok.now for the review. Well to start off, this amp is a very good value for what you get. It has a LOT of clean power. It has very good build quality and componets and a real pleasure to listen to. I dont even remeber what my first impressions were in particular (they were good though) but in my system this amp has very clear, airy smooth, detailed powerfull sound. Bass control is superb. Highs are not harsh. they are smooth and airy. Very black soundstage is thats how you explain it. It has alot of control and grace, on my speakers which are 4 ohm, it has no problem whatsoever driving them at high levels. the sound is never strained sounding. I just cant really think of anything else to say about the nad. It sounds wonderfull and i love it. Nuff said!
As for the build. the face and chassis is all metal. the rca plugs in the back are all gold plated and they arent going to pull out if you have tight fitting cables like me. The binding posts are a bit funky, compared to something im used to using. Its kina of hard to get a set of cables on the B output when your using spades. But they are very secure and do the job nicely. I will be honest, i have had the amp in for service once. About a month after i got it i moved my gear around and when i went to turn it back on the left channel was really weak. turned out giving it a nice tap on the side made the channel kick right back in lol. well in jan 02 i finally got tired of it and sent it in, the service center tried to send it back because he couldnt find anything wrong with it the first time, Bill at YAWA told me about it and i convinced him to have it sent back. turns out they found the volume pot was bad. I have had it for almost a year now sice i recieved the unit back and it has worked flawlessly since. Some people complain the remote isint good because you have to point it directly the unit but i havent had this problem.
NAD have been out there with their high end quality amplifiers for so long that many people believe that the amplifier was invented by them. Of course this isn't true, however it gives an idea of how 'sound' their products are.
I've owned this particular amp for maybe 4 or 5 years now and it's not lost any of the quality that it had when I originally bought it. For the price that I paid for it, which I am sure has been reduced dramatically, it is a wonderful piece of kit, that I now wouldn't be without. The sound is of great quality and is very high end, so much so, that you wouldn't know that I didn't spend thousands on it and in fact spent approximately $599.
The C370 is a cost effective system that is remote controlled and full featured. It also allows for the flexibility to evolve as your system grows itself. The power in the C370 is now Wpc, compared to the 317 power of 80Wpc. As well as this, the number of line inputs has increased from one to severn.
For me, the bets feature has to be the rear pre-out/main-in sockets which allow for an external pre-amp or power amp to be input. This means there is no longer the need for those pesky jump leads.
To conclude, this is a great piece of kit, that I love even more than when I first bought it and wouldn't replace just yet, despite the fact that I've had it for 5 years, showing just how well it wears.
A fantastic product with an impressive sound, for myself personally I use amps on a weekly basis as I am a part time DJ and sound engineer its essential as you could image for me to use the best quality products to ensure the quality and sound I am listening to is top notch. For the price and quality of the nad I would see its defiantly an amp I would recommend, you can go wrong
A fantastic product with an impressive sound, for myself personally I use amps on a weekly basis as I am a part time DJ and sound engineer its essential as you could image for me to use the best quality products to ensure the quality and sound I am listening to is top notch. For the price and quality of the nad I would see its defiantly an amp I would recommend, you can go wrong. The sound is crisp, the base is punchy and has all the features you could expect from a high quality amp. In my opinion I feel this is one of the best products on the market and I would go as far to say its one of the best I have personally used. I listen to allot of urban music, some which have allot of baselines and strong drum beats, so as you could image I tend to like to hear the best possibly quality. The nad defiantly performed and did everything I could possibly expect it to. The only thing I could criticise is of course the price of the product and the size but I mean for what your paying for it is worth every penny spent. After careful inspection of the material the nad was made form I did notice that it was durable and I feel it would last a long time if looked after properly. The only downside is I don't think my girlfriend likes the nad, she says I spend to much time playing with it.
This NAD has been on the market for some time but the question is does it reach the standards which NAD have become synonymous with. Well firstly it is built like a tank, it is very sturdy and although not much attention has foced on the aesthetics, clearly this amplifier has been built to last.
Secondly it's power is almost a mirror image of it's colossal size, offering 120 watts per channel. This is important for two reasons, firstly some speakers have a higher impedance which basically means they are harder to drive and thus need more current, but secondly it means that the frequencies will not strain when you turn up the volume massively.
What this means in reality is you get to hear the full dynamic scale of any genre offering with great clarity. As sound quality is the most important aspect of any amplifier though, this is where the NAD comes into it's own. This amplifier offers up a huge soundstage for the music, decay between notes is clearly heard, the bass is very powerful, but yet controlled, offering definition to the bass notes and thus forgoing the boom which can sometimes be mistaken for real bass. Guitars are crunching, but with an openness to them, vocals have depth, soul and feeling and coupled with this, or as a result of these qualities music as a richness to it, or as sometimes described a warmth.
On the front of the amplifier there is a button which will enabled will give you source direct. This is something which has no right or wrong answer but simply allows you to bypass the tone controls with the idea of shortening the signal path and thus giving you less distortion in the sound. There is also the soft clipping feature, which automatically turns down the volume once the volume has reached x but this isn't really necessarily as anyone can hear when music becomes extremely strained and distorted.
However in addition to this for those who are looking for constant improvements to the sound quality, this has also been taken into account. If you look on the back of the amplifier you will see there are pre out connections, this will allow you to connect a power amp to this to give you further power, more control and even more head room. You can also add a pre amp to this In addition to this there are the usual array of RCA inputs allowing you to connect external devices like a television, external dac, ps3 etc.
All in all this tank is an excellent amp which delivers the slams, the transients, the ranges, with aplomb slam and gusto. Definitely recommended.
