Borresen X3 at 11k - its not even close
For new speakers I have to agree. Haven’t encountered anything close to as good for around $10K. The closest performing B&W, Perlisten, Sonus Faber and Revel all retail for at least twice as much. Some of those reach deeper in the lowest octave but the X3s match or outperform them on every other level to my ears. They X3s are the only remotely affordable speaker I know of that can match the speed and transparency of panels/planars, but without the typical drawbacks of panels. Some other dynamic-driver speakers can do this but none I’ve heard under $20K, especially among speakers that can be bought new.
It’s my understanding that Borresen set out to create a new benchmark for performance in this price class. IMO they more than succeeded.
