[net.audio] Review: NAD 3140

djb (08/03/82)

In response to the request for info on audio equipment, here is a review of
my most recent (and certainly most rewarding) audio purchase.

			NAD 3140 Integrated Amplifier
* 40 watts/channel (continuous into 8 ohms)
* power bandwidth 10 - 70,000 Hz
* rated THD 0.02%, ihf IM 0.02%, SMPTE IM 0.02%   (if you care about such)
* slew rate 30 volts/microsecond
* 3 dB dynamic headroom
* Price: $398.00 list, I paid $348.00 for mine.

			     Other Features
* Speaker lead compensation that attempts to correct for abnormally long 
  speaker wiring
* Soft clipping that makes clipping less sonically painful
* LED power meter on the front panel
* Pre-amp output + power amp input + bridging connections on the rear panel
* Switch selectable phono capacitance compensation.
* Separate input and recording controls so you can record silently from 
  disk and listen to something else at the same time.
* Subsonic filter
* lots more I don't remember...

(for more info, and to clear up or correct any of the above, see the
review in the March 1981 Stereo Review.  For comments on the NAD line,
and their technical approach to amplifier design, see Audio Critic - I
don't recall which issue, but there are only 3 or 4.)

I have been very happy with the 3140.  It has a clear, clean sound and is
quite durable.  The folks that sold it to me were enthusiastic about
the quality of NAD equipment and low rate of problems/malfunctions.
The 40 watts rating is extremely conservative, it can pump out 70 with
no strain.  I couldn't find a more capable, compact and well reviewed amp
for $350.00 anywhere.  I heartily recommend it to anyone looking for a
medium-price integrated amp.
