    Andy ... I have some unused XLR interconnects ... pm me your address if you want them, and I'll stick them in the post ... no charge, as I got them for peanuts.

    If the source/amp circuits are designed as balanced then they will usually sound better using balanced interconnects.

    If the source/amp circuits are designed as single ended then they will usually sound better using single ended Phono interconnects.

    There may be exceptions to these generalisations, but remember its not about the type of leads, as they are equally good over short distances, its about using the right leads for the equipments topology.

    Also, just because a unit has XLR sockets does not mean it is a true differential balanced circuit so do a bit of research before spending to much. On the other hand its easy enough to try if you can borrow some leads and settle on what sounds right to you.

    I like the robust no nonsense feel to good XLR connectors, but that has nothing to do with how they sound.

    I tend to disagree with your second statement Qwin, have never experienced a deterioration caused by feeding single ended source into balanced I/P.

    Not quite what I said.

    Edit: Re reading what I wrote it can be misinterpreted, I meant if both source and amp are balanced or if both are single ended, not a mix.

    I've always been single ended until I got my big Krell amp. It has both single ended and balanced inputs, but I need some little pins to short pin 2 and 3 together, or some such, in order to use the single ended inputs, and I didn't get any when I got it second hand. But it just seems that if the signal has to run through the balanced jack to use single ended, it's only making the path longer? I've been using microphone cable while I shop for decent XLR cables. I don't really expect a huge improvement by buying nicer cables, but must keep up appearances and all.

    The balanced inputs on your Amp will be the shortest path if it is a balanced circuit.
    If your source is single ended, there wont be much advantage using the balanced inputs on your Amp.
    To connect a single ended device to the balanced input just use a single ended to balanced lead, made up as follows:

    Use std balanced cable (2 conductors in a screen).
    At the XLR end use std pin out of Hot to pin 2, Cold to pin 3 and Screen (ground) to pin 1.
    At the phono plug wire Hot to the centre (+) and Cold plus Screen to the outer (-).
    That's it.

    Good quality microphone cable is just that, it is one of the toughest tasks for a cable, so if it was designed to perform well at this and over long distances it is more than capable of connecting your hifi. When looking at the "decent XLR cables" check the spec isn't worse than the mic cable.

    The DIY Klotz MC5000 interconnects that everyone hear finds so good are made from mic cable, you could do a lot worse than making up a set of leads with this.
    I use it throughout my fully balanced system, with the exception of my balanced Turntable leads which need to be a lot thinner in my case. For this I use the Sommer SC-Goblin, which is a miniature mic cable, but still of high quality. See my DIY cables below.

    I thought your previous statement was very clear Quin.

    I agree fully with your last post, having used Van Damme and Klotz, and for the 2 pins" you refer to AlphaGT, I use just a length of tinned copper wire. It is a bit od a pain though, as is soldering XLRs, they wriggling all over the place on a table top on the end of flexible rubber coated mic. cable.
