Power Conditioner vs A/C cables

A power condition that generates its own pure sine wave output is worthwhile to completely remove line noise.

Shielded power cables stop Electromagnetic Interference emanating from the cables. Certainly EMI is present in the environment, but it is still important not to add more in close proximity of equipment.

If you are really serious, both are crucial!

Power ‘filters’ are terrible, they normally take more away than help the sq. You want a power regenerator or use balanced power to get the best out of your system.
How much to spend or how much improvement you are going to hear all depends on the quality of your system and your hearing. To actually state the a $20 cable is all you need is foolish for example, even a pioneer system would probably see an improvement with a $20 cable. A dealer friend did a demo for me on a system that cost around $20k. He made 1 change that I couldn’t see what he did and it made a huge difference in sq. All he did was to replace the stock power cord on the Mcintosh amp to an entry level red dawn nordost power cable. This was almost 20 years ago and ever since, I have always used the better power cords on all my components, which have been much more expensive than the red dawn

Ralph, at Atma-Sphere has one of the best Power conditioners you can obtain at the moment. Elgar Units that were made many years back still are much better than anything made today. It a proper Labtory Power condition using the fastest response time.

Watched a video today on power conditioners and regenerators and it seems lots of people overlook DC effects on their power. There’s more gear than not out there that doesn’t properly address it.

Ted dennehy, do you use OCC single crystal wire? And if you're just using ofc then your wire is behind the times because it's been proven for 40 years now that OCC single crystal is far superior to anything ofc.
