View Full Version : Praise for a mains plug!

Rather surprisingly (for me), this post is to praise the MS HD Power 13A mains plug I recently purchased (from Dave at Mains Cables R Us - swiftly dispatched as ever).

When I built my Paradise phonostage it was constructed in an entirely dual mono manner - meaning that two mains leads were required. I was starting to get a bit short of sockets so built a custom 'hydra headed' mains lead. This lead used Belden 19364 cable and both leads were terminated by an MK Tough plug. The problem is that two lengths of Belden terminated at one plug represents a heck of a lot of cable and copper for the plug to accommodate! Even after a bit of plug customisation it was still a real struggle to fit everything in and I wasn't really happy with the results - I needed a 'beefed up' plug. Unfortunately, all I could find were the usual 'audiophile' options and, to be blunt, my opinion is that the majority of these are little more than a standard 13A plug in a fancy suit. However, the MS HD plug is a genuine attempt to provide a seriously beefed up plug. The pins will take much thicker cable than a standard plug (three times as thick) and the wire clamps in a better manner. There is also easier routing of the cable internally and the strain relief is really well thought out -I managed to clamp both the Belden cables side by side without any compromise. This thing is really well thought out and nicely made. I used the copper version (I can't see the point in further plating when the socket is copper and so are the wires) and the pins were very highly polished (not sure how much of a benefit this is as the connections in the socket certainly aren't, but I guess it can't do any harm). In Short, highly recommended.

Mark,

With regards to the "hydra" head cable design, is it simply a case of wiring up both leads into the relevant pins of the plug I.e. just like wiring a standard plug but wiring both power leads instead of one. I have the same configuration paradise as yourself and I must admit that I could do with a spare socket. Additionally was amp fuse did you use?

Thanks

Andy

Yes, that's right, you just wire them so that they terminate simultaneously at the plug. With the Belkin cable there is also a separate ground drain wire that should be connected to the earth pin - so in my case that means two lots of chunky earth cable and two ground wires, all wired to one pin - not a problem with this plug though. The plug has a 13A fuse in it but I seem to recall the actual power supplies have 2mA T fuses in them. The mains plug fuse is there to protect the cable, not the equipment, that's what the chassis fuse is for.

Thanks mate, always worthwhile checking up on the details. I think I'll order one later.

No prob, I think you will be pleased - I think you also use the same mains cable too? I also have a four way hydra cable that I use to power the amplification.

Yep Simon suggested using the screened belkin stuff and dave supplied it. I also use the same stuff to power my garrard 301. Amplification power leads come from some old isotek elite cables which are apparently a bit ham shank, so I may end up buying some more belkin off Dave and making a hydra for them as well :eek:. This takes me down to two sockets instead of four.

I remember reading somewhere that fuses are bad for sound quality and pointless as the circuit breaker is far more sensitive, is this true? I've wondered about replacing my switch based twin socket for something better and then looking at good quality mains cables. I even wondered if I could direct wire equipment to internals of the socket...

They stopped making that plug now so not many left, its not in the same league as the MS HD power one though.

Don't even think of getting rid of the fuses in your equipment or cables, they are there to protect you. Use better fuses.

As for unswitched wall sockets, that's the way to go. Have it/them installed by a qualified electrician.

Yeah, I have thanks Alan - I've even got one :). Didn't think of it for some reason.

I bought a copper MS HD mains plug after seeing the review in Hifi Pig.
It's excellent and easily takes thick cables, no swearing and cursing needed! :)

What power cable are you all going with for DIY? Beldin?

Belkin for me, and it's not beldin!

Are you sure you both don't mean Belden?
