Dedicated mains -nice addition

Agreed - well worth the expense and trouble. All you need is a handful of PowerLines and you're good to go.

i did this with my SN a few months back with 10mm.sq 60amp cable. great upgrade. sounds fuller and as you say the hum 99% gone...also made a decent 4mm.sq mains lead with....

Seconded.

Curious Rega, what brand/part number of outlets did you choose?

sorry, I do not know. The electrician purchased them based on what I explained to him and requested that they not be just a standard plug. He showed me a reciept from the supply shop. They were $10 each. They have an extra 90 degree slot on the ground side (i think it is the ground side).

I was surprised at how much I had to push to get the plug in the receptacle. Once it's in a little ways, it seems to almost "snap in" the last 1/4" or so until it bottoms out. The receptacle face is perfectly flat also.

The wire ends are hidden / protected at the terminal end of the receptacle. The breaker was standard.

Sorry so vague.

Mr Rega1

Next time I am in the Chicago area I'll pop round and retrieve my LP's and CD's if that's OK.....and I will even buy you a beer to celebrate their safe return!

Cheers

Jim

Not a problem, sounds like a 20A unit with the 90 degree slot. Just curious as to any preferences fellow listeners are using state-side. Glad it's sounding better considering the expense. I've found the same here myself.

Yes, that's what Rega's got. Same at my home and you do kind of need to "snap" the plug in. This was suggested by our dealer (JS) for the mains installation. No need to go with the orange medical outlets. Now, what about a 30 amp mains???

Cool...did JS recommend a specific brand? dD had mentioned staying away from hospital grade as they have some type of spark suppression coating/plating(?) I removed mine and replaced with a commercial grade minus the coating and *think* I heard a better sound. Could have been the fresh connections. The grip on both is excellent especially considering my old hospital-grade outlets were 20 years old!

Forget 30 amp lines, that's a code violation for 15A appliances. 20A is OK--standard issue for modern kitchens, workshops, home theatre circuits, etc. Referred to as a small appliance circuit according to code.

It's a real value for money upgrade.

I can't think of better for $225 (my cost here in Dixie)

absolutely!!! I was going to contact you and drop them off to your family. Still have the same email? How is the new job?

agreed. It is a small price to pay for clean (as clean as it can get) power to the kit.

I know its a code violation, but probably sounds great!!

Dave, no specific brand just what's mentioned above.

...but, nothing is worth your insurance adjuster turning down a disaster claim. As you might imagine, they'll look for any way out of paying. CK convinced me of this several years ago so I converted back to meet regs.

A single 15 or 20A dedicated line does what we need safely here in the US.

Gary,

I wondered about that a few years ago when I had several hifi only cct. installed.

At that time, I owned Krell kit and they recommended more than 30A service for their larger amplifiers. Almost all high-current delivery producers seem to go overkill on the amperage rating for some reasons.

I've opted for 20Amp with 10 gauge wire. Even from a 15A, the improvements were instant. Altho, I found out years later that one of the circuit is not as good as the other one. (Christ, I never thought I would do an outlet auditioning! )

Since then, I've moved onto a single-ended valve amplification.
Interesting tho, the manufacture told me that a 20A is better suited than 30A service for their amps. I can't remember any technical details but I thought it was interesting what works optimally depends on an equipment.

Also, a friend who uses Naim kit told me that actually a 20A amp is better on it than 30A. Apparently, he tried both. :x

So, a 30A service might not work any better than a 20A.

If I were to do it all over again, tho, I would make sure I would listen to the wire in both direction.

Regarding Hospital grade outlets, my previous power cords broke two of those ( I didn't realise they come in different strength ) and now I use WattaGates which I can't recommend altho, mechanically they are robust and very sturdy even with heaviest power cords.

You could start auditioning different outlets and outlet covers, too.

LOL...I draw the line at outlet covers;-)

Gosh - $200/$225 is dirt cheap by comparison to the UK. The same work would be double that - at least!

Now I'll really feel bad when I mention that was for *two* dedicated lines installed side-by-side;-)

I wanted to test cable directionality (both runs off the same spool but reversed) and experiment with which electrical phase sounded best. Figured whichever line I didn't use would run a space heater in this basement playroom.

I may have gotten a discount as well. I had the firm install two more dedicated lines elsewhere for non-hifi reasons and perform some additional electrical work also. Total bill was for $500 US.

I agree Frank, we are fortunate in some ways like that.

I believe it is due to the economy and the lack of work out there. And as I found out, running cable in homes is different from state to state here. In my home state they run wire next to the studs and staple it, providing a difficult task to pull wire for new outlets.

In illinois, all wires are pulled through pipe / conduit. It makes it much easier and efficient to run a tape to the main panel and pull new wire.
