QSA 15 Amp Male to 20 Amp Female IEC Power Cord Adapter

Some components have a 20 amp IEC inlet, and your cord may be a standard 15 amp one. This QSA adapter bridges the two, with a 15 amp male end for your power cord and a 20 amp female end for the component's inlet, and it puts QSA's treatment at the last connection before the power supply.

Bridge the connectors, and treat the connection.

The Design

QSA says its treatment, which it calls MMMAT and MAT, makes electron flow through the metal more efficient. QSA keeps the process to itself, so we judge it the way Stereo Times' Clement Perry says he does: by listening. The adapter is plug-in, with nothing to open or modify, and comes in levels from Yellow to Crystal Gold Red.

Our impressions of the ladder: Yellow is the entry point and a worthwhile step; Violet is more natural and musical; Red is where the QSA character becomes unmistakable; Black/Red steps up image density and resolution; Gold is QSA's reference level.

Our Experience

In our experience a QSA adapter at the inlet lowers the noise floor and brings more resolution and naturalness. We offer auditions at the higher levels before you buy.

Where It Fits

The lowest-rated part of the chain sets the limit, so with a 15 amp cord feeding a 20 amp component, confirm that the component's draw stays within the cord's rating. QSA adapters are made to order, so they are special order and non-returnable; a trade-up program credits what you've paid toward a higher level.

Press Recognition
