Lehmann Black Cube question


This phono pre has been around for some time,
in production.

Does anyone here who has familiarity with this unit
know about what sort of evolutionary changes the
Black Cube has undergone over the years ?

If one were to purchase a used Cube, are there any that
might be considered "better" for one reason or another,
or are all versions just fine ?

Thanks much for any insight.

The original Black Cube had internal dip switches for setting gain and loading. Subsequently, a small hole was cut in the bottom of the box and these switches mounted on the bottom of the board so that you could get to them without taking off the bottom cover, but the circuit remained the same.

Next was the SE with the better designed and bigger outboard power supply, also offered as an upgrade option to existing Cubes.

I get foggy here, but more recently, I believe that the whole circuit was reconceptualized.

The originals, with our without, power supply are not just fine and not worth owning in my book. No doubt, others will feel differently depending on their tastes.
I bought the original Black Cube when it first came out based on the over-the-top reviews and user comments. Big mistake! It sounded mediocre at best. I don't know if later models sounded better (I would certainly hope so), but I would be skeptical.
The original Black Cube was the worst - sounding device I've ever heard in my system. It was efectively a PRaT filter: everything played through it came out sounding torpid and uninvolving. To cite one example, on the wonderfully driving "Sing, Sing, Sing" from Benny Goodman's 1939 Carnegie Hall concert, the Black Cube made Gene Krupa sound like he was playing underwater. The original BC was allegedly improved a little by replacing the stock power cord, but I didn't care enough to try that. You should definitely audition before buying.
