Black Cube:

cult object

since 1995

The Black Cube phono
stage is well known to
analog enthusiasts all
over the world.

®

Since the market introduction in 1995 the Black
Cube phono stages by Lehmannaudio have be-

come cult objects for analog oriented music lovers.
Countless positive reviews and awards, and an un
rivalled customer satisfaction worldwide document
this truly exceptional success.

The Black Cube is produced in small numbers and
sonically superior to mass industry products.

The Lehmannaudio Black Cube phono stage is
compatible with practically all available cartridges
on the market from High Output MM to MC. Apart
from the standard switch settings there is one on
board slot that can be fitted with a custom impe
dance to supply perfect termination even for the
most exotic cartridges. No more need for expensive
impedance plugs!

The input stages used in the Black Cube can also
be found in top notch mixing consoles or in well
known professional microphone preamps. The en
tirely passive RIAA equalization network is realized
with high precision foil capacitors. All resistors are
of the low noise metal film variety. The switches for
gain and load settings have gold plated contects.

Hear one now!

Because of the small outer dimensions the
Cube can be placed next to the turntable. This mi­nimizes loss due to cable lengths. The low noise re
gulated external power supply is connected perma

­nently to the audio section to minimize the number
of contacts in the signal path.

Lehmannaudio always pays special attention to
details: the cable between power supply and au
dio section is shielded. The cases of both the power
supply and the audio section are made of nonmag
netic materials and the case of the audio section is
even equipped with a top cover coated with a special

anti-resonance treatment.

Reviews:

03 2001

Colours, impact and thrust in the lower re-

gisters, room presentation and „objective
precision“ leave hardly any wishes unfulfilled. (...) The
Black Cube could handle all cartridges equally well and
conveyed their specific sonic footprints to the preamp
without any loss.

Especially the resolution (...) is
phenomenal. (...) Captivating in the first place is the
downright sound-engineer-like neutrality. Euphonic,
„analogue“ cosmetic treatments do not exist, instead
the listener finds one self close to the vinyl.

02 2000

From the outset, the Cube impressed with its ability to
swing. (...) It may surprise you what can be done for
under $700. It shocked me.

05 1999

Without the slightest hesitation or reservation, I can
wholeheartedly recommend the Lehmann Audio Black
Cube phono stage for inclusion in any high-end analog
playback system. It offered performance comparable to
my reference phono preamp for a small fraction of its
price and I‘d call that a bargain - The Best I Ever Had!

10 1998

I can‘t honestly think of anything near
its £395 price tag which even gets within spitting dis
tance. The Cube should keep those vinyl junkies out
there misty-eyed and defiantly anti-digital for a long
time to come.

12 1997

Something magi­cal was happening here, yet at this price?
(...) for the money I‘ve heard nothing that
comes even close. This unit is very highly
recommend. You don‘t owe it to yourself
to try this unit. You owe it to the music.

The Black Cube, though still a new kid

in the block, can be easily considered a
„classic“, a challenge for every HiFi manufacturer. (...)
Any serious analogue-addict should listen to it before
buying anything else.

11 1999

After the obligatory 10-day burn-in time it was soun­ding absolutely incredible! In fact it was the undisputed
best phono stage my ears have heard for under $1,500
and the Black Cube would retail for about half that!

perb. Talking about the more obvious characteristics,
the noise levels are extremely low. (...) The near-total
absence of electronic noise unmasked detail I had not
been aware of before. (...) A high-quality phono stage
for the serious LP enthusiast.

I found the performance to be su-

I‘d say if you‘re unhappy - or,
especially, bored with your phono section, and you‘re
on a budget of $1200 or under, get your hands on the
Lehmann audio Black Cube. I don‘t know of anything at
or near the price, that sounds this good.

The rave reviews of the Black Cube phono stage are focussing on the stunningly high product
quality and the outstanding price to value ratio. However the number of satified customers is
even of higher importance to us. This number is constantly growing. When do you join?
