    One per port? Certainly looks like it. :eek:

    I try to keep an open mind with audio tweaks. After all, stuff we now take for granted such as cabinet bracing, rigid stands, and equipment spikes etc all started life as some Herbert's mad idea. This one though stretches the bounds of credibility just a bit too far for my taste.

    Networking gear uses differential amplifiers. The Ethernet cables are four pairs of balanced line connections. Any noise picked up in the cables should be cancelled out when the signal reaches the RX amps sitting behind the connection pairs in LAN socket. Noise is further isolated in LAN connections because the specs require transformer coupling. IOW, the sort of low level DC noise that this magic plug is supposed to eliminate is already killed by the transformer coupling (galvanic isolation) inherent in Ethernet connections.

    The other thing with an Ethernet based network system is it has error correction. If there's a data corruption in one of the data packets then the system can (or should) request a new packet.

    Of course all this isolation can be undone if using shielded cables because they link the chassis of various devices together.


    What worries me is some of the claims made for this little device. You can read the blurb here: https://www.coherent-systems.co.uk/acoustic-revive-rlt-1 The part that caught my attention is in the paragraph headed Vibration Control, and they're talking about how this device makes the flimsey housing of a router or switch "stronger" and more resistant to vibration -


    "By using the RLT-1 with network equipment, its un-sturdy housing is reinforced and it results in the improvement of sound quality by eliminating the blurred sound image and improving energy and density, etc."

    That's a claim I'd love to see them prove.


    This device comes from Japan. It's a land that takes obsession to new heights. Hi-Fi is no exception. They've also got quite an odd way of distributing power, so maybe these little tweaks have some benefit for a few mad souls with nutter Hi-Fi systems where the environment is electrically very noisy with RF interference?

    Of course you do, along with oxygen free copper LAN cables. :)

    from the wiring guide mentioned above

    "All mains sockets sound different – often each socket in a double sounds different! – and switched ones sound particularly bad. "

    wonder what drugs the writers of it are on

    I'm going to order some equipment from Russ Andrews.
    Think I'll buy a box of 10 sockets @ £89.00 ea plus 100 metres of cable @ £79.00 per metre and of course I will need the separate consumer unit to wire them to @ £269.00
    But before I do I need confirmation from someone that my listening to Radio 4 will be enhanced.
    Has anyone fitted this sort of system and, if so, am I going to benefit from it? :whistle:

    I suppose it a shame when you should factor in that as you get older the more cloth eared you get anyway.
