Stay away from the nad

djengan,

That particular model has 3 switches in a row that carry the audio signal on to the power amp section. 
Tape 2
Tape Monitor
Tone Defeat

These switches are rarely if every used so there are 3 chances that a corruption can occur. It will manifest itself with the exact behavior you describe. Anywhere from apparent shift in balance to missing a channel entirely. I have had several different brands come in for repair (years ago) that can be "fixed" by just exercising the switches.

Anyone else who currently uses something similar I would ask to try this - without touching the switches put on some high quality music and listen for a minute then  "exercise" the switches that you don't use and go back to the beginning of the track and listen again. It will sound much better and have greater detail and it didn't cost you a "ripoff" repair bill..

When the purity of any connection in your system is not right this happens. Interconnects that have sat in one position for months have the same problem. If you simply listen to music then twist the RCA connections by a barely detectable amount (enough to break and re-establish a better connection) your system will sound better guaranteed.

My first experience with the NAD T778

Iv’e texted NAD concerning hardware issues as well as software issues.

My NAD T778 has now been returned to the dealer for service.

 - Occasionally the front panel on the receiver don’t show on start-up.

 - I’m losing picture through the HDMI-switch when playing PS4/XBOX ONE S.

 - There’s also a software issue that’s been confirmed by NAD. Some of the saved pre-sets on DIRAC sometimes get lost.

 - The receiver is highly sensitive after disconnection the main power-cord, even though I’ve shut the main power button on the back of the receiver first. After the receiver been without power for a day, (and not in standby) – It’s acting strange. Sometimes for security reasons, I’ve unplugged the receiver during a thunderstorm.

 - When shifting movies with different formats, the receiver won’t switch between the different formats automatically.

 - The receiver eventually shut down, and wouldn’t start up and went completely dead.

 

This is a receiver for about 3000 euro, and the build quality is really crap. The sound quality is some of the best I’ve ever heard. But the build quality is really disappointing. I’ve asked my local dealer to tell me where It’s manufactured (China, or other country in Asia) But he could not give me a sufficient answer) Please text the following critique to NAD.

 The build quality is really disappointing. Not ready for market at this price.

 Please look at customers reviews on Cruchfield

 Build quality put's it to shame

 

The thing is; NAD T777 was sold out in Sweden at the time I bought the NAD T778.

Like all new models from NAD; especially the receivers; they suffer from what we call in Swedish: “Barnsjukdomar”, translating: “The diseases affecting a newborns during their first year”.

 This is no excuse. The company sells NAD T778 at a hefty price: 3000 euro, and refer to it “Their reference avr”. I’m having a hard time figuring out what’s so special about it?

The specs are there, as well as the sound quality, but mine has broken down after only two months.

 I grew up during the 80-ties, with my dad buying “The Monitor Series”. At the time NAD was a brand to be reckon with! There’s been no problem with this power-amp, expected from a faulty left channel after 30 years, and which can be expected, as well as forgiven.

 f you read about the NAD T747 you’ll probably see that it was actually Philips receiver disguised in a NAD box. The same goes for NAD Silverline S300, and where customers eventually found out that it was a Gryphon.

NAD today is still selling their established concept “Music First” but they’ve been sloppy ever since the early 2000.

 My father bought the NAD T754, and had to return it due to a bad subwoofer output.

The subwoofer was making terrible noises even though not receiving a signal.

  personally owned the NAD T753v2, and was experiencing hum in several speakers.

The dealer later discovered how internal cables was moving freely inside several of these receivers delivered from the factory; and how the cables unfortunately got in contact with sensitive components inside the avr. So as a result of this: NAD decided to put all their sensitive components on separate circuit boards instead. I had to return this unit for a brand new one, and this was 2005 I think?

I got in contact with another customer with a different problem: The NAD T787. The owner told med about this unforgiving hum due to two oversized trafos, which was too big to function properly inside the smaller box. The customed sent the unit back to NAD several times, but never got it performing the way it should.

So why am I still buying in to the company’s concept? I guess it’s due to the nostalgia.

As a kid I grew up with their “no nonsense philosophy”. My first integrated amp was the NAD 3020, a great sounding receiver for a 16 year old getting his first hifi-gear ever.

 NAD today is just another sloppy brand, which has been compromised – buing low level components from other manufactures. I guess this what happens after hifi-brand’s been around for a couple of decades.

 

I don’t think I’ll settle for a new unit, and with great sadness leaving NAD for Denon instead.

I’m a current T778 owner as well and my unit is in the shop. It’s the most unreliable brand I’ve ever dealt with but it has the best sound quality that I’ve ever heard in my life. Obviously a love hate relationship.
