I would say the monoblock amplifiers of your choice that has sufficient power.Ah! So they were finally sold... hopefully the new owner appreciates these full range stats, they're one of a kind and no longer made. A rare breed indeed! I truly believe the new owner should be enjoying some fine tunes!
Ps. Any idea on what sort of amplifiers were been used with the CLX's? Always interesting to know about other brands and types of gear.
