Poor power in the house


Just moved house and had the electrician come and redo the fuse board and give an overall inspection of the house.

Its ok for normal stuff but my setup - Rega Brio and Planar 3 could do some a nicer supply.

Just wondering what I should be looking at, I see a lot of conversations about power supplies and cables but a bit lost on what I should be looking at.

The power in the house not the power coming to the house

Was thinking of getting the Rega Power cord and the TT PSU, but open to other suggestions, I am based in the UK too.

Thanks

To do completely separate circuits requires separate service drops, too.

As long as the grounding points are physically far enough apart (I think it's more 30ft), I think you're good. Been a looong time since I read NEC and no idea if this to code...

I wouldn't normally recommend messing with ground path at the service side, but I've found so much gear grounds in the signal path instead of via chassis that sometimes it takes extremes to cure ground loops. Better to deal with grounding at the interconnects but back feeding can be a big problem. I recommend series protection (something like ZeroSurge, Brickwall) to avoid the problem. 

Hey at least it's better than just lifting the ground (I've seen this way too many times).

one way to fix a shunted system is to isolate each ground wire (basically a dedicated ground per device) buts usually much cheaper and easier to go another route ...
It's not clear what you mean here. For safety reasons, and to be NEC compliant, all grounds must be bonded together at the service panel.
I should add and clarify... with separate circuits, the common mode ground will connect across interconnects in the signal path (which may or may not be good depending on the equipment) IF the interconnects are unbalanced.

True balanced ICs between gear made for (alot of manufacturers fake balanced internally) is best.

With separate circuits, but common ground, you SHOULD be good.

Isolation transformers on the ICs is another way (Jensens are great).

For UK, 50Hz hum would be a ground hum and either lowering resistance in the ground to balance it out, breaking the ground with iso transformers would do the trick... lifting the ground at the interconnect (receive end only) works, too, as long as you don’t have lots of RF interference.

Low frequency noise could also be DC in your power (which is really bad). Talk to your power company and have them fix it. Big, heavy and whining (they tend to make a high pitched sound) transformers are all you can do to scrub DC yourself. PS audio makes great but pricey regenerators and iso trannys for this.

High frequency noise is RF and you need shielded ICs or balanced if your equipment has it.

Power issues are a pain.
@mental  one way to fix a shunted system is to isolate each ground wire (basically a dedicated ground per device) buts usually much cheaper and easier to go another route.

Seperate circuits and grounds for amps and another for sources works well and is doable for most people. Balanced interconnects between the two is even better.

A shunted breaker feeds back into the ground...which is not good for sensitive electronics.

ZeroSurge makes a bunch of good gear to clean up power and keep transient surges from backfeeding into ground lines (they patented series line surge supression). They in the East Coast timezone in the US (-5 GMT). Call them up and see if they have any suggestions.

PS Audio also make some really nice power conditioners, etc. 
Definitely. Aftermarket (audiophile) power cables do make a difference in sonics. But it takes some research and auditioning to find the right cable.
  Check online to see what other Rega amp owners are using. Check the Rega forum.
 
Thanks for the replies have been looking into surge protection, also the TT PSU as well.

What about for the AMP? Would a decent cable help there also? Been looking at these -  Stratus 7 Power
I agree with adding a dedicated line for your audio setup. Have the electrician install this wire to your circuit panel. Your HiFi kit will then be isolated from all other devices and appliances in your house.

You should have surge protection for your components. A whole house unit installed by an electrician may be expensive. You can use a high quality power strip with surge protection for your components.

Adding the TT PSU would be a good upgrade.

Well, a dedicated line to your stereo system would be a good move.
I would also add a whole house surge protector to the main box. Most are sacrificial, but considering how often a huge zap happens, it is money well spent.
They shouldn't be too expensive, I got mine from Home Depot-I don't know the UK version of Home Depot.
After that, power cables, I would suggest Audioquest, but their are many other brands, and other Agon members will give their suggestions.
