Frequently Asked Questions about the
MODULUS 3B Full Function Stereo Preamplifier
What is the minimum break-in period for A.I. equipment?
It has become common knowledge that all high-end audio products require a break-in/burn-in period. Audio equipment can sound somewhat harsh and two dimensional until various internal components have broken in. Minimum “break-in” time for our preamps is 3-4 weeks of normal operation.
Should power conditioning or noise filtering equipment be used?
We believe that our tube preamplifiers should be plugged directly into a discrete wall socket providing the AC is reasonably clean. However, if excessive residue of DC or other artifacts are floating on the AC line, we then recommend a quality conditioning device.
What is the normal delivery time for A.I. equipment from date of purchase?
All Audible Illusions products are “made to order” and require a minimum of 2-4 weeks for delivery from time of purchase. However, for convenience to their customers, some of our major dealers do maintain limited stock.
