Dedicated Lines & Power Conditioners

I agree with Tvad and Shadorne, and will add: ALWAYS start with dedicated circuits and good outlets (like PorterPorts or Jena Labs) and listen WITHOUT additional power conditioning for a while. If you're still hearing some problem, or you just want to experiment, only then add your choice of power conditioning. After several days of listening with the power conditioner, once again remove the power conditioner and listen for several days. As Tvad says, your ears will tell you what is best for your system.

Sailfishben, just another data point: when the dedicated circuit is installed as a home run line from a single outlet to the circuit panel (as I believe many of us have done), an additional benefit gained is not having any connections or splices in the line. Every time there is a connection (whether through a junction box or an intermediate outlet on the line, even if unused), there is the opportunity for micro arcing at that connection. This introduces distortion spikes on the line and these spikes can have an impact. So, when we talk about running dedicated lines, we should additionally make clear that these ideally should be dedicated home run lines to each outlet.

Sorry to have injected an inaccurate/spurious term ("micro arcing") in the discussion. I couldn't think of a way to describe the phenomenon that has been explained to me. My poorly stated observation is that anywhere there is a connection, distortion can and likely will be introduced on the circuit. (As has been explained to my by more than one systems controls engineer who deal with industrial control systems as found in nuclear power plants and chemical production plants, these distortions are easily seen with the kinds of test used for final tuning of these control systems, and they can play havoc with the system.)

Whether there is arcing or not, Jea48 has identified the potential concern very well.

The point is: avoid the connection and eliminate the introduction of yet another distortion to your system. If you're serious about installing dedicated circuits, install them as home runs with one home run per electrical outlet. If a connection is unavoidable, use a top performing contact enhancer like Walker Audio Extreme SST.

Sadownic, did I do something to ruffle your feathers? Your posts strike me as someone approaching this discussion as if it were a contest. If I misconstrue your intent, and you simply wish to insure that information shared here is accurate, then I welcome your continuing efforts to share better information with us. But as to the use of dedicated home run circuits as a "best practice," I think I shall continue to recommend that to those seeking some practical advice on trying to get the best sound they can from their home systems.

Sadownic, sorry I missed your 9/21 post. Technical input and discussion are quite welcome. Imo, a discussion from which I can learn is always useful and appropriate; it's the reason I participate in Audiogon.

Regards,

Hardly providing technical input in that last post of yours, Sadownic. Oh well..., I see this is not going to become productive.

Jea48, thanks for finding an example. This is consistent with why to avoid any greater number of splice or connections in a circuit than minimally required. Oyaide certainly has a reputation for good sounding outlets, even if I've preferred non-plated contacts.
