I notice that while I am turning up the volume (either manually or with the remote) on my integrated amp, there is a slight crackle that accompanies the music. It stops when I have completed the volume increase. I haven't noticed this before.
The only things I've changed are connecting my turntable through the Bellari phono tube amp through Aux (previously I connected it directly to the internal phono stage of the amp) and I have upgraded the speaker cable. Or does my amp need a service (it's only about 2 years old -- the Marantz PM 7001)?
Any advice would be greatly appreciated. Thanks.
