    I refer anybody disagreeing with me to Barry’s detailed post above. Chris, yes it’s not a folly for the designer but it is for the consumer who has no control over such design aspects. The measurements on DIY audio where done by an established RF engineer along with the TDR results. Also, there was something about the canare plugs having to use the matching RCA socket to meet 75ohm but if that is really necessary then you may as well use the cheaper and proven BNC connectors instead.

    I like the connectors - they appear to have been crimped onto the outer braiding/shielding. This is important, as the interconnect has to be treated as being an RF interconnect. So, no place for crappy 'bullet' plugs here.

    Yup they are crimped on. Quite thin cable but it is nice

    It doesn't matter they are thin. True, thicker cables will have a lower RF loss, but as we are only talking a metre or two here, loss is largely unimportant.

    A better look at size of gauge and of the plug.
    Pi to vena and sounds better than last one. Much smoother imo. Timing flows better

    decay is better too..

    If this wont do it , nothing will. Read the specs in description.

    It's physically impossible for an RCA 'phono' plug to have a characteristic impedance of 75Ohm. Disappointing to read a company such as Canare propagating the myth of 75Ohm RCAs; crimped or soldered, it makes no difference. But as I commented on above, the effect of the mismatch is relatively small (hence Canare's claim of a mismatch VSWR of < 1.1).

    I was pointing to the cable specs as far as bandwith.
    But it is true all round connectors will be under 75 ohms.
    Amphonal makes some of the best commercial connectors for coax , I wish they did more for audio.
    There BNC stuff is really good.

    My endeavours in this make me think that all digital cables get the signal to the other end completely unaltered as otherwise we would hear clicks or pops. This applies to usb, bnc or optical. The difference is in whether they also transmit unwanted RF noise overlaid on the digital signal and which will eventually get into the dac analogue stagecand and cause intermodulation distortion. To avoid this, optical is best in theory because the optical only transmits the digital signal and not any overlaid RF noise.

    On this basis, the difference in sound of different digital cables comes down to how they handle RF noise. More noise equals a bright or false sense of detail. Less RF noise is indicated by a softer or darker sound.

    Cables selected because they have more detail are almost certainly transmitting more RF noise.

    So, my suggestion is to select whichever digital cable has the darkest, least bright presentation. That one is then transmitting nearest to the bare digital signal and therefore is closest to the original musical file.
