Hello from France

I've just joined the forum. I live in the mountains on the French / Spanish border. I regard myself as an accidental audiophile. The better the reproduction, the more there is to feel, the richer the emotional experience. I now have slightly above high-street level kit, but I struggle to keep up with the technical side of it all.
There are issues still to resolve. Current projects are:
to add remote control to my valve amp so I can use the fixed outputs of my network streamer, which makes a huge improvement to music quality;
to try the Cambridge Audio CXN V2 as a replacement for my Marantz ND8006 streamer which I don't get on with very well.

Greetings and salutations, I joined the forum a few days ago with the intention of learning something new.

Using the TDA7439 and Arduino, I have constructed a remote-controlled volume and Bass/Mid/Treble system. Additionally, TDA 7439 supports four inputs, and individually inputs gain can be adjusted by the remote control.
