Summary:
About a year ago, I got my hand on a NAD 2400 ($150)(Not the THX stamped model, but the org. PE.). My taught was to use this amplifier in bridged mode driving a sub. I could not decide if I were to build this sub myself or buy a sub-kit (-amplifier), so I decided to test the amplifier in stereo. However I rewired my NAD 320 and used this to drive the new amp, curios about how this would sound. And WOW!, the result was amazing! I’ll guess the C320 lacked the power to control my fairly large speakers, but the 2400 definitely didn’t. Kept playing my CD-collection over and over again, amazed over all the details I newer had heard before. (This was also improved by a using a dedicated preamplifier C116.) As I was surfing the local HiFi ads, I found a second NAD 2400($280) (Mint) and I bought this just for test how the stereo would sound with a bridged NAD2400 per channel. And again the result was more than a noticeable improvement. The bass is now even more rock solid controlled, than what was the cases when using a single NAD2400, and also more details are revealed in the upper frequencies. Major benefit using the bridged amplifier per channel was that the stereo image was much improved. Buying the NAD stuff second hand is a good investment.

Strengths:
Power controll and good freqency responce. Value for money, can't be better.

Weaknesses:
Ugly design, not as stringent that on newer nad equipment.

Summary:
What a solid power amp? Reserves of power to tackle any material you can throw at it. Extremely musical and neutral sounding. I had used only a vintage NAD3020 with my kef coda 7s, then added this amp with the 3020 as a pre-amp as I was listening to more and more orchestras and d n B. My speakers were on the list for the next upgrade, but the 2400 made them sound so much better than with just the 3020 that I still haven't found a need to. They don't make them like they used to, this is made in Japan and feels like it will last forever. Keep the power on at all times to keep the electronics warm, cycling power can reduce the life of this amp. Enjoy!

Strengths:
Power. Able to power 2 speaker pairs. Build like a tank. Make cheap speakers sound a milion bucks!

Weaknesses:
Boring NAD grey...but looks rather good if you have matching NAD equipment to go with it.

Summary:
I've had this unit for a little over a year, and I must say; this is one of the best investments I'll ever make. I also have the 2600, and when you have these two units working in tandem you will experience a bit of magic. I only use the 2400 for my rear speakers, but it could easily run my main speakers with no problem. If you like to listen to your music loud and clear then this is the amp for you. This amp will make lower quality speakers sound better then they were designed to.

Strengths:
Where do I start?

Weaknesses:
None that I can think of..

Summary:
This is a surprisingly good amplifier given the price. Prior to this I used a pair of Marantz MA500s and they were ok. When I got to this it really opened up the music. I originally intended to use it through a mid-high end receiver (as preamp) and just power couple regular speakers, but I ended up plugging it directly to a CD player (it has gain control) and it sounds even better than my other Yamaha RX-V1 setup with the same model speakers.

Strengths:
Sufficient power for most speakers. Very balanced and smooth sound. It is also relatively feature-rich for an amp because of the A-B switch and gain control. Soft-clipping works well too.

Weaknesses:
None that I can think of at this price range. I did hope for better binding posts though, but banana plug is good enough for me.
