Not sure for power conditioner my amp or not.

Hey, 

No amps on power conditioners. If you have a really nice preamp that stays off the conditioner too. If you don’t believe me then play three songs with your amp plugged into the conditioner. Then plug it right into the wall, wait three days, and play the same three songs. Only change this one thing. That way you know it’s the amp. I think the power conditioner can starve the amp and /or color the sound based on what technology it is using. During heavy lightning storms or when on vacation I unplug all of it. 

Hey Facten,

Sorry for the delay. If the capacitors discharge then he the op will need enough time for everything to charge up and level off. This may not be for 100% tube amp. That might only need a day. I have tested a lot of power cords and components. I mean a lot. I do not want to get into an audio war. I just wanted the op to have a totally fair a/b test. You can usually tell right away if you test with the right tracks that you know well and have a good ear. I doubled my outlets from two receptacles to four receptacles and plugged everything but my sources into them. All sources went into the “conditioner” I use Puritan 156 with the Puritan Ultra XX power cord. Nordost is killer stuff but I would spend a lot more than I wanted to. I also have the Puritan GroundMaster system with two 8’ copper coated rods outside my listening room. 

Hey Smoornc,

If you have all of your components plugged into the same surge protector which is plugged into the same outlet then it would be grounded together. One problem is some manufacturers float the ground on the power cord input. In that case they are not grounded together. 
Also, Most grounding rods connected to your breaker box are not for audio. It’s there as a safety measure. Plus, the products builders use can be ridiculous. Like pounding in a metal conduit pipe and using it as the ground. 
Star grounding from the chassis is great!  Especially if the manufacturer did not ground from the power cord. It also helps eliminate noise.

Signal ground is different. That is where you are using the negative terminal on your interconnect terminals connected to you equipment chassis or back panels. I would say leave signal ground alone unless you talk to a dealer. You can mess up you gear real fast if you short a class D amp or a balanced amp.

Puritan is a unique product line that can take care of all three. They even have a product called GroundMaster City in case you can not install your own grounding rods outside your building. It works upto 85% as well as the GroundMaster with the rods. Great for multi unit dwellings. 

Hey Facten, 

The only tube equipment I have for now is my tube preamplifier. It’s an ARC Ref 2 SE. I only have it on when listening. It has a lot of capacitors so it needed about a day and a half after I moved the power cord from the Puritan to the wall outlet. You can usually tell that something good is happening right away. I just like to be fair and compare apples to apples. Also, Anyone thinking about a Puritan product. The power conditioners take 12 days to break in. I call it the 12 days of Christmas. The first day it’s great because it’s the first present. Somewhere in the middle you get socks and underwear. That sucks! But somewhere between the 10th and 12th day you get the big gift- awesome sound! Or back in the day an Atari 2600 with games. I’m telling you this because I own two of these and they both did the same thing. I hope this helps.
