We tried the SPEC amps here, they didn't sound ' right' and if you used a source with a highish output voltage they would pop and spit viciously , run to save the speakers vicious, I did write to the manufacturer on several occasions but the next model we received suffered and sounded exactly the same.
Another Uk distributor has taken them on now, I believe.
