NHT CLASSIC FOUR SPEAKER SYSTEM, CONTROLLER

PRE/PRO, AND POWER5 AMPLIFIER

overboard. Yikes! The Classic Four’s
low bass was deep enough to com-
municate the unbridled horsepower
of the scene. The NHT ensemble’s
visceral sound is just plain scarier
than any sub/sat system I’m familiar
with could ever hope to muster.

The remastered DVD-Audio disc

of David Crosby’s 

If I Could Only

Remember My Name

is a trip to the

outer fringes of hippiedom, circa

1971. Supported by a slew of
fellow travelers from the Grateful
Dead and Jefferson Airplane,
Crosby made a perfect musical
time capsule. The surround mix
knocked me out, but, even in stereo,
the sound possessed a flesh-and-
blood natural quality.

The 

Pixies Acoustic: Live in Newport

DVD’s unplugged vibe is a nice
contrast to the band’s usual electric

edge. The warm blend of guitars
and Kim Deal’s bass guitar sounded
sweet, and, now that I can hear
every word in Frank Black’s twisted
lyrics, they’re even weirder than I
had thought. The Classics’ sound
kept surprising me, especially when
I played my reference discs, stuff
I’ve heard on what seems like a
billion systems. My respect for
Lucinda Williams’ 

Live @ the Fillmore

CD kicked up another notch.
There was something about the
yearning in her voice that really
touched me. The low-level detail-
ing and the ability to hear the
concert-hall acous tics were extra-
ordinary. Yeah, the system’s powers
of persuasion were clearly work-
ing their magic. 

Just to convince myself that the

sound wasn’t just a magical synergy
between the NHT speakers and the
electronics, I hooked up a $1,500
A/V receiver to the Classics, and
their sound still shone through. It
was very sweet, big, and powerful
but nowhere as transparent, and the
bass definition loosened up a
smidgen. Still, it’s hardly a fair com-
parison—a $4,750 surround-
processor/power-amp combination
should sound a whole lot better than
a $1,500 receiver. I guess it all comes
back to the maxim that the whole is
greater than the sum of its parts,
and, in this case, the parts are plenty
outstanding on their own. The Clas-
sic Four system takes it to another
level. 

> All channels driven continuously into 8-ohm

loads:
0.1% distortion at 257.1 watts
1% distortion at 299.1 watts

> Frequency response:

–0.29 dB at 10 Hz; –0.09 dB at 20 Hz
–0.27 dB at 20 kHz; +0.68 dB at 50 kHz

This graph shows that the Power5’s left amplifier
channel, with two channels driving 8-ohm loads,
reaches 0.1 percent distortion at 291.6 watts and 
1 percent distortion at 349.5 watts. Into 4 ohms,
the amplifier reaches 0.1 percent distortion at
538.9 watts and 1 percent distortion at 640.2 watts.
An input level of 117.0 mV was required to produce
an output of 2.83 volts into an 8-ohm load, indi-
cating an overall gain of 27.59 dB.

Crosstalk at 1 kHz driving 2.83 volts into 

an 8-ohm load was –109.0 dB left to right and 
–106.78 dB right to left.—
