Summary:
I'm reviewing this after using it for several years, and replacing it with new electronics (read below). I was using it to power a pair of Paradigm Reference Studio 20's. Music was largely classical and jazz.

At the time I purchased, it seemed like the best choice, but now I wonder. Compared to what I'm currently using (an Outlaw RR2150 receiver), the NAD's sound is too laid back, too sterile and uninvolving. On the positive side, it's fairly neutral, and does well with voices (which is probably why I bought it back then). But it really lacks presence and provides insufficient detail. Soundstaging is inferior to the Outlaw, too. These flaws are magnified at low volumes.

And the NAD has a design flaw, one that I found the hard way. When you plug in a headdphone, it automatically shuts off the speakers. One day, I wanted to listen via headphones, and when I removed the plug, the tip stayed in the jack, which rendered the amplifer useless. I couldn't anyone to fix this trivial problem for less than $200, so I tried to fix it myself. Bad idea.

So while this isn't a terrible product, I think that there are probably better options at or near the price point, at least if you like the same sort of sound that I do.

Strengths:
Attractive.
Well built.
Good remote.
Neutral.

Weaknesses:
Too laid back and clinical-sounding.
Insufficient sonic "presence"..
Lack of clarity and detail.
Flat soundstage.
Poor low volume performance.
Poor design re headphone jack.

Summary:
To make it short, it's a very good amp in it's price range. I listened to several amps around this price, and even the 600$ rotel amp sounded bad to me (just my opinion, but it sounded wayyyy too metallic).

The NAD sounds natural, and the sound is exceptional, if you ask me. I have 2 bookshelf speakers and my amp could blow them away before distortion occurs.

Strengths:
Cheap
Powerful
Good sound

Weaknesses:
Volume control knob does a skkrrrrrr sound sometimes when listening to music. You have to turn the amp off and rotate the knob to min/max volume several times, and the problem is gone for a while.

Slightly off center with headphones. You have to adjust slightly.

Thats it.

Summary:
I purchased the amplifier for the following application: I have a modest home theater with a 30" Toshiba CRT, a pair of Klipsch Heresy speakers (pretty efficient), and a DVD and laser disk player. I wanted to use the amplifier for audio switching and volume. I wanted to replace a 1990s Yamaha AV receiver that was too big and had a lot of features I was not using. The setup is shared by a decidedly non-enthusiast wife, so the setup has to be very turnkey. So basically I was looking for a low cost integrated two channel amplifier with remote and switched AC.

That pretty much narrowed the field to the pioneer elite (too tarty looking, and I am a bit offput by their putting the elite badge on midfi gear), and this unit. I got a decent price on a used NAD, so I picked it up.

Right out of the box, I noticed a major bummer. The AC plug in the back was unswitched. This is contrary to what NAD advertises on their Web site ("the C320BEE also has an AC switched outlet ... so you can easily switch your entire system on or off with the remote control or from the front panel"), and pretty useless (note to NAD; I have an unswitched AC already; it is called a "wall socket"). So this means I can't use the amplifier to power on the TV.

There is a fair workaround. The unit will react to three different power signals, power on, power off, and power toggle (the third one is undocumented and not on the supplied remote, but it's what goes to the power button on a universal remote, and handy to have). So I dedicated function keys to each source on my universal remote (a oneforall 9910), and programmed macros that, in addition to selecting the video and audio source, sends a power on signal to the amp. Then I programmed the sleep button to turn off the TV and power off the amp. Switched AC would be better; just assign power toggle to the power button, but I *think* my wife will be OK with the extra key strokes.

Probably no big deal to most folks, but since the company falsely advertises a feature, I thought it would be worth noting here.

Strengths:
None that jump out at me. This is a cheap looking midfi amp, but priced accordingly.

Weaknesses:
Kind of cheap looking, even in this price range. Even the remote is dowdy looking.

I own an NAD monitor series receiver and Yamaha AV receiver, both around 15 years old. Much better units (but they cost more dough). Would have loved to have used the NAD receiver for this application, but it has a really stupid defect on it; you have to press two buttons to fully power it on. I think NAD considered this a feature, not a bug, at the time, but I think they have stopped implementing it.

Summary:
I would like to share my observations having used this product daily for the past 1.5 years.

Although it's good value for money and I would not replace it with any other product in this price range, it has a few shortcomings.

I'm very happy with the sound. I use it for music CDs, DVDs, and TV. I have used several different speakers including Wharfedale, Energy, and Fostex. My current Fostex speakers allow the NAD to perform to it's potential.

I use it with a NAD C521bee CD player, which is a good match in terms of price and performance.

Strengths:
- Good power amp section (see below regarding pre-amp).
- Pleasant sound, I would call it accurate and lively.
- Great value. In my opinion the sound quality far exceeds other mass market brands in the same price range.
- Pre-out / main-in jacks allow upgrades. Upgrading the pre-amp to a better quality unit allows the power amp to perform to it's potential.

Weaknesses:
- Preamp section is not that great. I believe the potentiometer is not good quality. The left / right levels do not match (slightly off center image). Scratching sound from right channel when moving volume up / down, probably due to contaminent in pot. This is only noticable with high efficiency speakers, and has been resolved by working the volume control through the minimum / maximum range several times.

Summary:
This is a wonderful amplifier which does almost everything well and is very cheap.
It produce a smooth, natural,musical and enjoyable sound but for that you must place very well this amplifier on a rigid and right surface otherwise you will have a harsh and strange sound. I also advice you don`t put that device on cd players or under, just place it very well and alone.
When i bought that amplifier before i tried the Cambridge audio azur 540a but the nad c320bee was really better.
I use it with a Nad c521bee, sony stsdb900 , Monitor Audio B2, cyrus biwire speaker cable, Van Den Hull The name and qunex 1 as interconnects.

Strengths:
Smooth, natural,musical and pleasant sound.
Good timing.
strong dynamics.
That amplifier plays very well piano.
It give you music music with hapiness

Weaknesses:
None
