The Lehmann Audio Black Cube SE Review (and why there’s no going back now)
Thursday, November 6th, 2008

I’ve been thinking about upgrading my phono stage for as long as I can remember. It was the one remaining component left to upgrade after the turntable, tonearm and cartridge and now I’ve finally done it. Wow! What a huge difference.
I originally bought my Music Fidelity X-LP phono stage when I purchased my Unison Research Simply Four which was sold ages ago. The guy in the shop said “phono stages are basically all the same” and that it wouldn’t really matter which one I bought. Also, I didn’t have the £500 in my pocket for the Unison Research valve phono stage!
Anyway, to cut a long story short, changed Unison amp for Decware Select Zen amp, built loudspeakers…sound got better but still a bit thin sometimes. Upgraded turntable to excellent Origin Live Ultra, got Origin Live Silver tonearm, new cartridge, new speaker cable, Vertex AQ Jaya mains filter and eventually built new Decware HDT speakers.
Each time I upgraded these components the sound became more detailed and more refined. When I got to the Origin Live Silver tonearm, the Vertex AQ Jaya filter and especially the HDT speakers things were getting extremely good and new experiences like spaces around instruments, a defined soundstage (including the first signs of depth) and tonal details really started to make themselves known.
But still the sound could be thin with vinyl, especially some bad pressings like Living Color “Time’s Up”, and The Pixies albums. I had high hopes for alleviating this problem with a new phono stage.
So, I spent a lot of time researching this component. I considered Graham Slee’s Era Gold, the Trichord Dino, the new (and well reviewed) Pure Sound P10, the Moon LP3, various Pro-Ject stages, Tom Evans and quite a few others. After reading lots of opinions, though, I discovered that the Era Gold and the Dino wouldn’t necessarily bring a lot of “body” to the music, the Moon was a bit of an unknown, others were less flexible and the Pure Sound P10, while raved about, is Moving Magnet only.
One phono stage kept coming up in my mind, the Lehmann Black Cube, especially in its Special Edition version with the add-on power supply. I kept reading great reviews which really talked about qualities like soundstage and especially its “full bodied” tone and wide bandwidth. Other bonus points for the Lehmann were that I could buy the Black Cube and then get the power supply later, making it a more achievable purchase and also that it has a number of user-definable settings such as the cartridge loading, custom loading (by inserting resistors), low pass filter and gain settings.
Wow, this is a long introduction! I will try to speed things up a bit. I purchased the Black Cube, and pretty soon after added the power supply to turn it into the Special Edition version.
The result was actually far more than I was expecting, from a phono stage upgrade. Having got used to fairly subtle improvements in sound from changing various components the Lehmann Black Cube SE made the music gel in a very impressive manner. Not that it wasn’t pretty coherent already!
The soundstage was very much more defined with instruments clearly positioned now. Yes, the Decware HDT speakers did this very well but now there was more depth front to back, too. Also, even more attention grabbing is that before, certain instruments and voices had a wonderful sense of their own space. Now, with the Lehmann in place, everything imparted its own space. Every single element of the recording now breathed, reverberated, sang in a space and position within the soundstage.
You might think that this definition and pulling apart of each instrument would have a negative effect on the overall sense of musical coherency but I was delighted to find that it actually pulled everything together, I was really getting into each track and enjoying the music on a new level.
Another amazing aspect was that, while seemingly tightening up the sound over all frequencies, my previously unlistenable recordings became listenable! High frequency sounds which, I guess had been more blurred, focused into well defined elements and the result was no more splashiness and painful (for my tinnitus) sound.
To the same degree, the bass reached down deeper but stayed tight and together, with many interesting new textures emerging from the depths. The speakers help of course, being single drivers, they’re so tight and fast that you really get some explosive dynamics.
Music from Calexico, Spoon, Menomena, David Byrne, Buena Vista Social Club and Ladyhawk really revealed just how startling the togetherness and sense of space had now become. Finally I feel that I have achieved the system I’ve dreamed of for years! I’m not suggesting the Lehmann Black Cube SE made that all happen, of course it was just the last part of the puzzle, but it’s pretty much impossible for me to clearly define which component brings which aspects to the audio reproduction. All I can say is the music now sounds…musical! Highly detailed, with an expansive yet focused soundstage, tight and fast, full of the subtleties of tone which really make it all sound so enjoyable.
I’ve written so much I feel I cannot go into why “there’s no going back now” in this post, so I will write that next!
