I was thinking I was close to 275+ hours. But now all it takes is about an hours time for the amplifier to start from cold and sound so delicious! I am glad I to be in this Accuphase Club - I have not heard my music sound so glorious, so clear, so non-fatiguing. And that bass - that keeps the excitement ON. I have said this before and will say again - this amplifier sounds far too powerful than my previous amplifier which was rated 4X powerful as this Accuphase.
@willywonka - I saw your posted the pic of your new amplifier in the system. Do share what you think about it's ability to drive your speakers. And what the other posters say is absolutely true - need to wait at least 200+ hours to understand and appreciate what an Accuphase can do.
