Break in period for tube amp. How long?

Can you please share your experience on break in time and initial sound of new tube amps. Mine are sounding awful out of the box (NAGRA VPA).

You described exactly how I felt. Well now, after about 25 hrs the VPA's are opening up......the best yet to come I'm sure, as you suggest.

I went from ARC VT100 MKIII to a used pair of NAGRA VPA's. Well, I was so impressed with the improvement (dynamics,air, soundstage, placement ambience etc.) that I upgrade to the current new VPA model. With the new unbroken in model, however, the sound seems congested and harsh........i.e.awful. I'll try to break them in to 100 hrs as suggested. So far I have about 10 hrs break in time.

I am using the same speakers B&W CM4 as I await my ordered PARSIFAL OVATION's. Thanks for your input. C123666 how would unbroken in capacitors affect the sound?Thank you
