The Cryo Edition version is similar in construction to the standard version. Only in the Cryo version, all metal parts that can be found in the loudspeaker are cryogenically treated one piece at a time. The parts are cooled down to -196 degrees Celsius and slowly brought back to room temperature. As a result, the internal molecular structure changes, and the stress from the materials disappears. The cryo treatment is done in-house at Børresen Acoustics itself, it is an expensive process but yields a substantial gain in sound quality.

The Silver Supreme Edition is again the same as the Cryo version, however, this version utilizes hand-cast and CNC-machined pure silver induction rings in the drivers. These drastically change the properties of drivers, in a very positive way. The inductance is about 12 times lower than that of conventional drivers and the distortion is reduced by as much as about 40%.

One final bit of advice is that the seating height is fairly critical. At 44″ from the floor, the tweeters are significantly higher than your ears when you are seated in a normal-height chair. If you have a low-slung couch, as I do, the tweeter develops a shelved-down response above 2kHz. The tweeter will sound nice and mellow, but will diminish the instrumental timbre I’ve discussed, due to the reduced level. I had to remind myself to sit up straight to get the best sound from the Evoke 50s.
