I have heard many of them and owned two pairs. I went up the line from Scansonic MB-6B to Borresen Z3 Cryo to Borresen 02. The 02 are still to this date the best speakers I’ve ever owned. I am a dealer for a few other brands, not Borresen, and I still think the 02 beats everything I’ve had on my floor. Unfortunately they will have to go at some point as my business continues to grow. Since I run my dealership from my home, I only have so much space.
I’ve spent a lot of time with many models. In addition to the ones I’ve owned, I’ve heard the X3, 01, 02SSE, 03SSE, 05, 05SSE, M1, and M3.
While the Z3 Cryo I owned were a lot of fun and a great speaker at its price point, the 02 is a bit more refined and holographic. It can still fill a medium to large room without an issue, as long as the electronics can control them. I find Borresen are a bit harder to drive and quality electronics matter. I had great luck powering them with the T+A HV stack, Audionet electronics, and Luxman Class A amplification. I’ve never owned Aavik or Ansuz gear and cables to pair it with.
My favorite quality about them is their ability to image. They can make for a truly holographic soundstage and not be fatiguing at all. They are super fast, yet refined. It is really hard for a speaker to do both exceptionally well.
