McIntosh MC402 Burn in Period ? Very Impressed

Hello everyone.

I just bought myself a brand new McIntosh MC402.

After spending about an hour unboxing it I was ver y impressed. Getting back to unboxing I have to give kudos for the nice packaging to safely support the 150lb package.
Two boxes plus screwed on to to a wood board.

I am using all Bmi cables' balanced interconnects, speaker cables and power cable. The MC402 sounds wonderful out of the box. The only thing that is funny MC402 comes with a cable cover for the speaker cable ends, that is a waste because the holes are too small for any Bmi hi end speaker cable to fit thru.

Have to say this MC402 is the quietest power amp I have ever heard. The amp is dead silent when left on. Plus the amp runs cool.

When should I expect total break in on the McIntosh MC402 ?

I own a 352,the predecessor of the 402, and I beleive that when I bought mine I really think it was fully broke in after about 50 hours. McIntosh doesn't really address this anywhere that I can see, like some manufactures. But give it about 50 hours, crank it and love it. I hear from so many people that McIntosh is not as good as other brands and that may be so but I really don't think I will ever sell my Mc amps. I was going to upgrade to the 402 but since the 352 is ecentially the same I am adding the LED lighting from AudioClassics and plan to enjoys the music.
Enjoy your amp!

Mine was great out of the box as yours seems to be. May have gotten a bit warmer after about 100 hours but did not need any burn in to sound great.

I purchased an MC402 here on Audiogon so I assumed that no burn-in would be required. However, I was very underwhelmed with the sound initially. After roughly one week, the amp really started to open up and is now everything I would want in a power amp - dynamics, musicality, detail...
