MK Logic vs Crabtree

Posted by: bunter on 27 November 2010

Anyone have any thoughts on which is the better quality unswitched socket? My local B&Q has both.

Take a look at this thread:
MK Logic Plus

lovely, thanks!

although, having looked closely at that thread, I feel not much the wiser. I suspect any new socket, with untarnished connectors is likely to sound better though...

There is no absolutely right or wrong answer I'm afraid, only opinions. I think the MK Logic Plus range is pretty good so I use them on both my HiFi circuits and elsewhere in the house. My wife likes the rounded edges too so that helps Winker

It depends on how far you want to go - dedicated consumer unit, 10mm2 radials, posh sockets, powerlines etc....

Just reading the thread MK Logic plus, and a few very interesting points.

just wondered if everyone is using Twin&earth or TRI Rated SWA?

Also why bother with Sockets when a flex outlet cuts down on a contact surface, plug pin to socket receiver? bit of a pain when a storm comes (unless its on a dedicated mcb)

Flex outlet option would have been acceptable 16th, but would need to browse the iee for latest reg compliance.

I would happily go for a dedicated radial etc, but living in a rented property makes this a no go. I have found in the past that simply replacing a switched socket with unswitched makes a positive difference.

bunter, your question is like asking wots the best car/TV/beer/cable, you will get more diverse answers, obscure flat earth theories & looney toon replies than flea's on a dog.

There is no answer other than MK & Crabtree are the best of the bunch & that includes those rare-air others that cost a kings ransom because of the matt black, smoked mirrors & slimy snake oil & sound so good they nearly match the MK & Crabtree's.

The MK & Crabtree in most of each's mechanical & deffo in sonic terms have sweet FA of a difference.
Ask SHMBO to choose for you, this will get you some Director of Domestic Affairs HiFi buy in, she might even encourage or even approve your next upgrade bug.

lol, yes, didn't really realise what I had stepped into there. Have just replaced my old MK socket with a shiny new one. Old one was definitely showing signs of corrosion. New one seems to sound better - so I'm happy Smile

Mains Cable R Us do a silver plated version of the MK for a decent price. Whatever you believe about silver plating, it should help with reduced corrosion longer term.

Think you need to ensure the outlet is adequately fused, i.e. 13A max. Would have to double check on Regs though as I'm not sure it allows a "free" end, i.e IEC socket. Think it needs to be hard-wired throughout, like with an oven, which seems sensible.

at that price I could replace my MK eight times! I have to admit I am curious how one of these would sound... A lot of people here are like vampires or lycanthropes in their attitude to silver.

with rhodium-plated contacts, FP-1363 is BSI 1363 compliant and uses a nylon/fibreglass body and Alpha Pure Copper conductors. Its clamping system can accommodate cables up to 5.5 mm2 and provides 17.142% more contact area than the designs you are considering. Alpha Phosphor Bronze Pin Supports ensure excellent contact and handling characteristics. A low-temperature two-stage process begins during the manufacturing process with a deep cryogenic freeze of all metal parts using liquid helium for temperatures between -196 and -250C. Treated parts change their structure as molecules bond together more tightly to improve electrical conductivity and power and signal transfer.

i have got a singe version of this and my view is that it is very well made but unfortunately cannot take 10mm sq wire, so will use it with 6mm sometime

enjoy

my wife would literally kill me if she found out I spent £130 on a plug socket. Do they make one that looks more like an MK? Winker

Does anyone have experience regarding the Furutech sockets and a view as to the rhodium versus gold plated versions - I have been advised that the gold is the better to go for from an accoustic p of v, with the rhodium having a 'bright' sound, but a much better material.
Thoughts anyone ?
Cheers

Well they do, and the right socket of the Crabtree sounds better than the left. I can hear it and so should you. I've offered a charity based challenge to some other doubter and I'll offer it to you.

Also, read the link DaveBk posted.

A bit of research will show that Phosphor Bronze is a worse electrical conductor than Aluminium. This has also been posted on this forum before.

The forum would be lost without the technical inputs from people like yourself. Also, it never surprises me that these people don't take up my challenge to make free money.

Take the challenge, post pics of it, post results, post whatever you wish, my money is waiting.....or shut up. Leave your email address and I'll contact you.

If you believe you can hear a difference, great, but don't get so excited, its a FORUM not an academic think tank.

Your challenge is seriously flawed I am afraid, your understanding of statistics need some improvement
500/100 will give such a questionable result - no matter how good (or lucky) your selection (bet) - that it proves nothing.
500/1 will give a more credible result, 5000/1 would better satisfy statistical technophiles like myself.

BTW (1) - you are correct about Phosphor Bronze conductivity, but who sez low resistance gives "better" sound
BTW (2) - my system uses as much silver wire & connections as available in an attempt to reduce resistance. Does it sound better, who knows, but it stops me & my techno-physic getting concerned & avoids the upgrade bug (for the time being) Winker
