I have a X6
Pros: super resolving, clarity, quickness, dynamics, bang 4 buck
Cons (relative, compared to a couple of other speakers in a similar price bracket):
Instruments sound more like instruments on my Yamaha (NS5000). It doesn’t image as well as my TAD....Very finicky with placement and sub integration, both of which are easy as pie on the TAD.
Other: I wouldn’t pair it with AGDenmark amps. Other brute A/AB amps seem to sound better with Borresen speakers (my ears/opinion).
