Børresen Acoustics Z1 and O1 Review

March 12, 2023 Comments Off on Børresen Acoustics Z1 and O1 Review

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%.
