They tried to deliver it today but no one was in (unfortunately I gave them my work email address and they emailed me last night to tell it was being delivered so I only found out once I'd got to work!). I'll attempt to pick it up tomorrow morning from the sorting office but if the queue is too long, I'll go for a re-delivery on Friday.
I have MERLIN cables on My DVD player,AMP and Plasma and there IMHO definatly a slight improvement to overall proformance but this improvement was not as big as to when I replaced the Mains cables all the way back to the RCD Power board but naturally this is not a cheep option, but depending upon when your home was constucted may have a vast improvement on all electrical equipment within your home.
There is a viaible alternative to these expensive £200 a metre power cables which IMHO give just as good a result. I have just help My Brother set up his system and I found a Guy who makes His own power cables at a fraction of some of the prices mentioned in this thread, andwhen I used them instead of My Merlin cables just too see what they were like, the results were equally as good as the Merlin's. (If you want Prof, I can send you his info over XBOX LIVE)
I am a strong beliver in using quality cables, but £200 for just over a metre of power cable is madness and definatly carrys a nice litttle profit for the makers!

Indeed, interested to try all kinds of cables so if you can message me his details that would be great. Always happy to save a hundred pounds if I can!
Thanks matey
Thanks matey
trevor79:I have cut down on the number of individual fuses myself and used circuit breakers instead to provide protection. (reduces the line inductance off the mains) This helps as well to make your system sing!
Trevor - this is new and exciting news to me. How would a circuit breaker reduce the line inductance of the mains?
If a fuse did somehow add a significant amount of series inductance wouldn't that only help filter out spikes from the mains? Which is why someone (someone from here a while ago described it to me when asked - like I am now!) found using a variac to supply the mains helped.
Cheers

I use one of these on my PS3 / the rest of my gear and they're great. The power chords I got from them are far better than my old Russ Andrews reference plug and also much cheaper.

Have a look here, As I said I used these on a mates system and good cost effective results. http://stores.ebay.co.uk/Audio-Friendly-Shop_W0QQsspagenameZMEQ3aFQ3aSTQQtZkm
Circuit breakers have a much bigger contact area for the mains supply to flow through giving NO restrictions to the current. If you picture electricity flow like water down a tube, a larger diameter pipe will flow better than a small one.
A fuse however consists of only a thin wire who's resistance builds up until it melts (breaks) at its rated value. So on a 13A fuse running on say a 8A load the resistance (inductance) will be quite high which sounds terrible!
One of the main points when dealing with mains supply to sound and vision equipment is to reduce as much as possible line inductance. Personally I do not use any fuses, except inside the equipment and use a 20A circuit breaker in the consumer unit. They also react much quicker to a line short out.
Have been on holiday so sorry about the delay in replying.

The above is utter nonsense. A mains fuse has negligible inductance and even if it did it still wouldn't affect the sound in any way at all.
Caution. Never ever be tempted to bypass any fuses (they are there for a reason and you don't want to burn your house down).

Replacing fuses with circuit breakers are a big safety improvement as well, so your house will not burn down. As to inductance not having an effect on sound/signal quality, it does. Higher quality wiring, using circuit breakers instead of fuses give excellent improvements, as do replacing with Clarity Caps on speaker crossover boards.
Those who are content to enjoy there watching and listening without feeding an optimised, conditioned power supply don't know what they are missing, or talking about.
Don't knock it until you have tried it.

Pseudonyms, I think - but yes, agreed...

So how exactly can You use a plug without a Fuse? surely when You remove the Fuse the current will no pass through to You equipment?
Admitedly any spikes in Your power suply should never reach any electrical equipment as these provideing You have the correctly rated RCD in Your consumer unit, should result in the corrisponding RCD tripping out, but I could forsee just how successfull any insurance clame would be ifit were found that the were not any fuses in the units plugs.

Personally, running off a dedicated spur (not a house ring main) I run the line off a 20A RCD direct to a Tacima block on 40A screened cable with a strong earth. With all my equipment fitted with mains internal fusing I elect not to use plug fuses (contary to regs, I know) so have soldered wire across. If in the worst case of a short out in the plug it would blow the protection of the wire at both ends, so no equipment damage or fire hazards. I will probably get around to adding internal circuit breakers to the units later.
I do not advocate using mains supply without protection.

Running Your electric in this way sounds like it going to be fun when/if You sell Your house!
I had My sparkie install a seperate spur direct from the consumer unit for My setup using a higher grade armoured power cable for better power distrubtion,but the RCD in the consumer unit is designed as a first port of call should You get a spike but is not 100% and a spike can still get past it before it trips. Personally I think I will be sticking to a Quality Fused plug!
