Nagra VPA and Meridian 601 preamp.


Hello,
I am driving a Sonus Faber Stradivari Homage with Nagra VPA and Meridian 601 preamplifier using the balanced output.
when i power on the VPA and switch from mute to on (after 2-3 minutes) i hear a small 'bang' , then everything sound good.
what could be this problem?

It is not normal ! I have never experienced this with my VPA's. I would check with Nagra Service.
It is normal ,,, the relay in the VPA , it is used to prevent sudden voltage damaged the speaker unit... All the extreme amp have this features...
Mine also do this. Try leaving on for a longer amount of time. It could also be normal. Nagra has an office here in the states. they are good at answering questions.
