Bought this back in 2000 from a lical store in Bethesda MD, listened carefully in their sound room and really liked the sound even though my ears felt irritated, was on sale for $500 so bought it. At home I noticed again my ears were irritated, I can hear unusually high frequencies, talked with a audiofile and he said it needed to be broken in under load, played music fairly lound for two days, 8 hr a day nonstop, and my eats were no longer irritated. It’s now 2020 and it is still sounding great. If I put my ear on the grill of my EPI A500C speaker’s tweeter in a quiet room I can bearly hear a hiss in the left and right tweeters, and changing the volume does not affect it. Guess I got a good one!

The remote control is highly directional, thought it was just weak when I could not control the speaker mute from 15 ft away, but started playing with it and realized I had to point the remote front left corner level and right at the sensor and then it worked fine. For those with the left channel hum, maybe it is a bad capcitor, cheap to replace, especially if it has been isolated to the preamp, just need a good tech to find it.

i bought this amp for 50 euros,not much for an amp this age and still working so i don t recognize any of the crappy quality discribed in some reviews here.
The amp sounds very powerfull and has a nice warmth as well but to bad its not very dynamic and can sound slow and compressed sometimes.

I purchased this amp about 14 years ago,(brand new) and it has'nt given me any problems.there is a slight buzz in the left channel, but i can barely hear it. yes it's been there since new... I have a pair of energy c4s, and a rotel cd player hooked up to it every since I bought the amp. about 8 yrs ago I purchased the nad 214 power amp on ebay, and bridged them. their working perfectly! i'm very satisfied with my system, all I can say for the people that are experiencing problems is that the past owner may have abused the amp, or maybe mine was built on a wednesday.....

Hiss in left channel is real and a very common problem from brand new. Good sound and punch for the bottom end but this amplifier is fragile. It has been serviced twice for the same problem but never really fixed. It now sits on a shelf because nobody seems to be able to fix the problem. I have several NAD products and like the quality but the price is high. Other NAD amplifiers do not seem to have the problem the 317 has. I hope to get it fully repaired and back to work soon.

Very powerfull, but little bit too rough sound for my taste. Articulation mid and high frequensies is good, but this amplifier lacks some clarity in bass. I think this is very good amplifier for watching movies, but only semi good for enjoying music records.

Despite all of the bad fuss about the "buzz" in the left channel this unit produces, I decided to buy one from a local seller at a bargin price. After spending a few days with this NAD 317, all I can say is that I am totally impressed with this little powerhouse.

This unit is combined with an entry level NAD 522 CD player and pushes my Polk Audio SDA-2B's.

Very smooth, detailed sound with great bass response. This one is a keeper and for the price I paid it is a real bargin.

NAD and Polk seems to be a great budget combination for a regular guy like me who does not like to spend too much cash on his audio gear.

Simplictiy, durability, value for money

NAD components do not share the same exterior appearnce. Different swithes, colors, displays, corners.

Connected to Piega P4 speakers (from Switzerland): excellent sound, no problems of any kind for the last 8 years.

transparency, power, compares favorably to pre/power amp combos

slight buzz in left channel

I've been using my NAD 317 integrated for over a year now and it has performed flawlessly. I must confess that I became alarmed after reading some of the negative reviews on this website, but I can only relate to my personal experience. The hum in the left channel, as indicated by other reviewers, is real. Actually, for my unit at least, "hum" is really too strong a word. I would call it a slight buzz that is only audible when my ear is less than an inch away from my left tweeter. And my speakers, Paradigm Studio 40's, aren't exactly known for their treble reticence. Hardly much of a nuisance... I agree with the reviewer who asserts that the "hum" originates in the pre-amplifier section, which can easily be demonstrated by following his instruction.


Other than that, the 317 is one terrific sounding integrated amp, very open and transparent with terrific bass. The power on tap is amazing and comparable to a good pre-amp/power amp combo. I even compared my amp to the much lauded NAD C320BEE, which I borrowed and inserted into my system after reading all the positive press. The C320 didn't really seem any more transparent to my ears, but the loss of power and bass control was obvious. For myself at least, it was no contest. I can only theorize that the problems associated with the NAD 317 have either been greatly exaggerated, or both good and bad units exist. Judging by the fact that the amp was only manufactured for a relatively short period, I personally believe the latter to be true.

Over-priced, badly designed,

This unit started out fine, but after 3 years started having intermittent right channel break up, distortion, and etc.. I did some research and found out many NAD models have these sort of problems. I proceeded to contact NAD customer service and they gave me the "it's out of warranty" talk and as i looked more into the issue I realized that this is a design issue that NAD should have been responsible for. Everyone knows that amps sound better through time, however the volume and balance controls on this unit are soldered to a small pc board very badly. this board is not secure, so when the volume controls is moved around it weakens the solder joints and after time one or the other channel will start to fail, not to mention the heat that runs through the board. NAD refused to take any repsonsibilty, or even mail out the small part so one would be able to fix it themself, it's just 2 screws, a nut, and 2 cable connections. I was opting for a Rotel but Dr John at Sound Factor, Encino CA persuaded me to buy this junk. I would stay away from NAD like the plague, they package badly designed junk and sell them as high value audio gear by cheap design hidden by behind an expensive looking unit. If you look at Ebay when this amp shows up the sellers usually desribe the inherint NAD flaws. There are many other better choiices than NAD and better priced untis. NAD's lack of any responsibility to stand behind their product for a $800.00 unit is another reason to not buy their products.

Very Poor, NAD lacked repsonisbility for their product and were condescending in communication.

Heavy steel chasis gives impression like it's something more than it is. Just cheap electronics in a nice metal case.

Atrocious support from NAD

Garbage
The more you listen to it the more the problems add up. this amp actually sounds worse the more you use it. NAD decided not to do anything about the design flaws that would show up years later (after warranty of course) I contacted them as a lot of people have paid good money and ended up with a bad amp. NAD won;t do anything about it, stating that it is not under warranty. I believe NAD should have taken the steps to right this issue. They ended up ignoring me and pointing towards the nearest service center. NAD wants me to spend more money on their problematic integrated amp. If you do a little research you;ll find out that this model along with quite a few others have circuit design issues, the contact goes bad and you start losing a channel. I will never again buy anything from NAD again. I have a Pioneer receiver that has has lasted 5x as long and was $200.00. Sounds great and even works.
