Description

After 25 years of loyal service, the well-known Black Cube phono preamplifier is changing! And changes with Lehmann Audio are pretty rare since it had not been modified since 1995!

Among the Black Cube family, this new Lehmann Audio Black Cube II phono preamplifier is placed between the Black Cube SE and the Black Cube SE II.

LEHMANN AUDIO BLACK CUBE II: HOUSING

The Black Cube II receives the case and some of the components of the Black Cube SE II. But it comes with the standard power supply of the Black Cube and not the famous Lehmann Audio PWX power supply that remains optional, and therefore an upgrade.

So, from the outside, it is impossible to differentiate it from the Black Cube SE II. The housing is made of a specific non-magnetic aluminium alloy. It received anti-resonance treatment to limit the microphonic effects as much as possible.

It is associated to a nice natural or black-brushed aluminium front panel. An option also offers a chrome-plated front panel.

LEHMANN AUDIO BLACK CUBE II: CIRCUIT

The internal circuit is also very close to that of the Black Cube SE II and integrates the same quality of components. So we find the input stages taken from the professional world.

The equalization and correction part of the RIAA curve is completely passive. It is made with MKT capacitors and high-precision, low-tolerance, low-noise layered metal resistors.

LEHMANN AUDIO BLACK CUBE II: SETTINGS

Under the case, Lehmann Audio uses the traditional switch for the various gain, load and bass response settings.

The Black Cube II offers 4 gain settings (36, 46, 56, 66 dB), 3 load settings (47K, 1K, 100R) and 16 bass response curves.

One of the switches, called "Custom", triggers the resistive load (precision resistor) placed in the circuit by the user who wants a precise value more adapted to his phono cartridge.

LEHMANN AUDIO BLACK CUBE II: POWER SUPPLY

The main difference between the Lehmann Black Cube SE II and the Lehmann Black Cube SE II is the external power supply, which is actually, except for a few things, that of the Black Cube (standard).

LEHMANN AUDIO BLACK CUBE II: TEST AND LISTENING

When listening to it, the Black Cube II is relatively not surprising as it is very close to the Black Cube SE but it is not equal to the Black Cube SE II.

We find the transparency and neutrality of the manufacturer's products. The balance is quite "soft", even a bit dark with some phono cartridges.

However, this phono preamplifier is also very versatile as its balance does not favor one register more than the other. It is also more transparent and silent and dynamic than the Black Cube (standard).

As you can see, Lehmann Audio is not very original...

The Black Cube II phono preamplifier is a Black Cube SE II, but with the Black Cube power supply. If you add the Lehmann PWX power supply, you will have a Black Cube SE II in a little more expensive version...

So it is a good option for those who do not have the budget from the start for a Black Cube SE II or the excellent Decade.

Excellent

Novice dans ce genre de produit, juste après son arrivé dans mon système, son énergie perturbait, un temps soit peu, les bienfaits de la physique!
Après les bon conseils de Franck et à sa patience, nous avons rapidement trouvé ou le bas blesse!
Une subtilité presque improbable nous a amené à trouver les solutions, très simples, pour remédier à ce petit problème. Il fallait juste y penser! (Expérience Domotique)
Très bon produit, à la hauteur de sa réputation, rien à voir avec un pré ampli phono intégré, il ne faut pas hésiter à passer par ce genre de pré ampli s’il on veut gagner en qualité audio.
Je me permets de recommander ce produit tant pour sa qualité audio que pour sa fabrication.
Merci encore à Franck!
Jérôme
