Classe Audio CT-M600, CA-M600 specs

warm up/break-in period

please read this manual…

Your new Classé power amplifier will deliver outstanding performance immediately. However, you should expect to hear it improve somewhat as it reaches its normal operating temperatures and its various components “break‑in.” It has been our experience that the greatest changes occur within the first 300 hours, as the amplifier reaches thermal equilibrium and the capacitors fully form. After this initial break-in period, the performance of your new amplifier should remain quite consistent for years to come.

The only exception to this rule is if the unit is placed in standby or unplugged for an extended period of time, allowing it to cool down. Depending on the degree of cooling involved, you should expect a brief warm-up period (on the order of 10-15 minutes) before the power amplifier’s sound quality is at its best. Unless your amplifier was allowed to become quite chilled, subsequent thermal re- stabilization should not take long. Fortunately, you should never have to repeat the initial 300 hour break-in period.

Please take a few minutes to review this manual, and to familiarize yourself with your new amplifier. We understand that you are anxious to plug everything in and get started. However, reading this manual and following the advice it gives will ensure that you get all the benefits you deserve from having purchased such a fine piece of equipment.
