QUAD 405

Another masterpiece from QUAD, even if the revised "II" version sold better.

Stable, stable, stable: whatever the load, the tortured electrostatics, the storm blasting outside your cosy listening room : the 405 is of the immortal kind and like the 303, 606, 909, 50E, 501 or anything QUAD, this is gear you buy for LIFE.
