Which NAD pre- and power-amplifier are the best?
I would appreciate your experience!
My Revox B251 "gave up" and I would like to buy NAD pre- and power- amplifier. My requirements: - Musical sound picture and details (i have also a 3020i and this amplifier sounds really nice) - can drive critical speakers (I have Dynaudio 3-ways system); I am also thinking one day to buy Dynaudio Confidence 5 - good MC part for my Ortofon TMC 200 (low output MC) - shall additionally to CD have also AUX input How good are following NAD-s: 1155 1300 208 THX 218 THX Are there better ones? Remark: I am going to buy 2nd hand. Thank you! Drazen |

Remark: I am going to buy 2nd hand. Thank you! Drazen Drazen, I'd add the NAD 220PE amp to the list. Solidly built, really reliable, though I have had to replace the speaker relays in them. I've never compared them to the newer 208 or 218 for sound. I'd also consider the 1600 preamp/tuner if you want a radio. Regards, Tim |

Anything with the PE moniker, for instance. IMO, is a poor choice. Another excellent amplifier brand is Rotel. Well worth considering and, depending on your market, may be better value for money. There are other choices too. Trevor Wilson |

There are other choices too. I bought way too many junked NAD products that I have to fix, some I paid good money for. Like that 400 WPC stereo receiver, and that top priced preamp. Build quality is nothing more than typical. I was fixing a tuner/preamp and the obsolete tuner part made it difficult. Does NAD carry old parts ? I never tried contacting them. greg |

I never tried contacting them. greg Used to be they carried parts for older units until they just sold out. Don't know if that info still applies. NAD has "dual citizenship" inasmuch as they are equally based in Canada and the US. This might mean they don't pay typical US property taxes on unsold parts. I was informed that Yamaha recently just threw away a bunch of old parts rather than pay property taxes on them! Mark Z. |

Finally, I have bought a combination NAD 1600 + NAD 208 THX.
How good is the NAD 1600? As good as best pre-amplifiers like 1300? How good is the MC input at 1600? Drazen |

Trevor Wilson Not a NAD expert, really - but in my experience with NAD there is no more potential for damage to speakers than with any other amp with a competently designed protection circuit. NAD was always a bit spotty on reliability, not limited to their PE models. Long term heat damage to caps, resistors, etc for one thing; and the Taiwanese origin of many of their products wasn't so great either, from cheap electrolytic capacitors to somewhat shoddy physical manufacture. I've seen one or two British-built NAD amps which did seem MUCH nicer though. I would say sound quality of the PE series was probably at least average - though I've never had one at home, and so my impressions having only worked on them in the shop could be erroneous in this area...

Well, by "average" I mean that it would be rare indeed for anyone to hear the difference between an NAD amp of the PE series and any other competently designed amp, functioning properly and operating within it's limits, in a double-blind test.

The disaster potential built into PE equipped NAD amps first came to my notice when I was selling them. I sold a pair of KEF 104.2 speakers and a NAD 2200 amp to a client. He blew the tweeters in short order. I was surprised, since the NADs used ferro-fluid cooled tweeters and, IME, were indestructible (up 'till that point). I had sold quite a few pairs of the things. Fortunately, the local distributor of the KEFs was also the NAD distributor and I managed to squeak them though under warranty for my client. Intrigued, I put the 2200 on my test bench to see what was going on. After 30 mins of testing, it became abundantly clear what the problem was. It goes like this: As you are no doubt aware, most people who listen loud, turn the volume up, 'till the amp is just nudging clipping (slight harshness on loud notes). Naturally, those with alcohol impaired hearing will tend to crank the volume up even further, but let's forget that, for the moment. Anyway, it would be safe to assume that less than 5% of the programme material is in the clipping region and thus the harmonic structure is pretty much what it should be. Not so, the the NAD PE stuff. When the high Voltage power supply is exhausted (which occurs after a period of time in all PE amps), the clipping can be horrendous, amounting to easily 50% of programme material. The skewed harmonic structure can easily destroy tweeters (and mids). NAD was always a bit spotty on reliability, not limited to their PE models. Long term heat damage to caps, resistors, etc for one thing; and the Taiwanese origin of many of their products wasn't so great either, from cheap electrolytic capacitors to somewhat shoddy physical manufacture.

VERY average. The sudden application of a massive extra supply rail is not conducive to proper operation of an output stage. I hasten to add that several other manufacturers have used the same (or similar schemes) over the years. Trevor Wilson |
