Ok thanks for the tips.

Yes my system originally did have B&O cd player/ tape deck/ record deck connected via din plugs BUT the cd player and the record deck now need service or repair (the record deck needs a complete new cartridge, expensive). I have quite a long post about my problems with my cd player tray operation and drive motor spinning up too fast. Still no firm answers what to do or where to get serviced in the UK.

So meanwhile i have had to compromise and use some of the RCA inputs for namely:

WiiM pro plus streaming player (for streaming from mobile devices to the Aux input)

Rega RP1 (Now utilising the WiiM Pro Phono input via a cambridge phono line converter)

Sony Super Audio cd/ dvd player (now utilising the WiiM pro Optical input which then comes out of the Beomaster Aux input)

I 'broke' the Phono RCA inputs simply by trying to remove them to fit an RCA Socket to DIN cable for the Rega RP1, which failed miserably in swathes of feedback hum, i think because of the Regas lack of grounding cable.

So at the 'moment' i have patched in the sources i need bypassing the current faulty B&O sources unitl they can be fixed. To be honest it works quite well, having doscoverd the WiiM Pro can 'listen' for input sources so swapping from playing a record to a cd it automatically switches inputs, a little like the B&O operation.

I agree the entire system integration is desired but at the moment for me it is out of reach.

thanks
