Home Wiring?
I spent $400 adding two 20A outlets with upgraded wire (75' from my sub panel to my listening room) with audiophile grade outlets. My electrician found extra blanks in the sub panel and added the power easily. I also had the ground outside double checked and for whatever the reason my house has two grounds. Shynuata SR-Z1 are in my system. |
Unless you are experiencing some definite problem at the present time - such as an identifiable noise or tripping your breaker, going to dedicated lines is not going to make any difference whatsoever. It is important to have have a clean ground, a circuit that can supply the required current, and follow common sense procedures to avoid such things as ground loops. You are not going to gain anything from changing your outlets, wiring etc. It certainly isn't going to sound any different. As to outlets, the 2 dollar outlet from home depot is going to 'sound' the same as anything else you buy and going with different outlets wireing etc isn't going to matter. I spent decades working as a biomedical engineer, including advising, specifying, and selecting power distribution equipment for safety concerns, reliability, low noise applications, critical care environments and everthing that came up. My formal educational background in that field is a BSEE. From that background and experience I can tell you that 'improving' your power system just to make your audio system sound better is nothing more than a waste of money. |
No1willfan, in each of three different homes where I ran dedicated electrical circuits to my audio system, the improvements were very noticeable and worthwhile. I recommend you move forward with your plans if costs permit. This need not be a hugely expensive venture, but you DO need an electrician. What I have done each time is relatively simple assuming one has open tabs for additional breakers on the circuit panel: 1. Pull a separate 20 amp line for each electrical box. Don't put multiple boxes on the same line, don't have splices in the line, have the line pulled as a single continuous strand of cable from breaker box to outlet. 2. I used 10 gauge copper for my lines. Your electrician will tell you this is overkill. Do it anyway. I used standard "Romex" type cabling for two of the installations and I can't tell that I got any improvement running metal clad cabling in a third installation. (Assuming you are in a typical American house with solid masonry walls or wood studs (not a commercial building with metal studs), there is no advantage to running an isolated ground installation as I did with the metal clad cabling in one home. Just keep to single lines from breaker box to outlet and you'll get the same benefit.) 3. Use good quality 20 amp all-copper alloy outlets without any plating on the contacts. There definitely are differences in sound quality among the various outlets, but a primary factor is that the receptacle be built well enough to maintain good grip on the blades of the plug over time. I use the Jena Labs 20 amp outlets also sold by Walker Audio. These are 20 amp Hubbell all-copper alloy outlets that are deep immersion cyro treated. PorterPorts are also Hubbell outlets based on the Hubbell 20 amp outlet and deep immersion cryo treated. Both are reasonably priced, strong and long lasting, and with very neutral sound. 4. Buy some Walker Audio Extreme SST silver contact enhancer and have your electrician apply this at each electrical connection made in the circuit. (It will make a further improvement.) There are additional things you can do to further improve results, but the steps I've listed will give you a very nice improvement and not cost too much money to accomplish. . |
