Hi, I hope I can get some advice on the following.
I have purchased a headphone amp and to connect it into my system I decided the most sensible route for me was to connect it to my Integrated Amp's 'Tape Out' socket as this is a loop out bypassing the volume/tone controls. Out of interest for some reason I decided to measure the resistance of the 2 RCA cables I was using (CD Player to Integrated Amp & Integrated Amp to Headphone Amp. The cables are both the same and measured around 4ohms (both cables connected to each other were around 4ohms ) - However if measure the two open ends when they pass through the Integrated Amp (as described above) the outer still measures 4ohms but the centre is now around 580ohms.
Is this because the tape output sounds like its being controlled by a relay so possibly has some protection circuit. I am guessing this measurement doesn't really matter?
The other option I had was to have an RCA splitter at the CD output socket and run one lead to the Integrated Amp and one to the Headphone Amp. Any thoughts generally on connecting would be very welcome. (probably doesn't make any difference either way but worth asking)
Thanks
