Has anyone A/B'd these cabs? I have a PL210 4ohm ceramic that I am very happy with. But, I have been intrigued by the Berg CN212 and kinda just feel like getting something new. Any thoughts? Running a vintage Demeter VTB-201 with the internal Class D power section upgrade - much better than any external amp I have ever paired it with IMHO (including a few behemoth tube power amps).
