New Dedicated Line - Almost No improvement

Thanks All! My amp is a Primaluna Evo 300 integrated with tubes rolled. Power cord is a LessLoss entropic and also use that cord for my phonostage (ModWright 9.0x). 95% of my listening is vinyl. I also have a LessLoss speaker firewall(s).

What I have learned - which may be incorrect - from reading many threads and posts about power/line conditioners is it really depends on how dirty your power is. For someone in an old apartment in NYC with hair dryers being used all around them will have dirtier power than someone in a more suburban or even rural area (depending on those conditions). The house we left was at the foothills of the Appalachian mountains and we had our own transformer. I don't know if that helped or not but as mentioned the EMI reading was pretty low coming out of an outlet which was not a dedicated line. I think (!) this is why power conditioners make a big impact for some and not for others – depending on their system and listening preferences of course.

I've read more positive reviews about the Puritan PSM 156 more than any other (below $5k) and have been considering one of those but wanted to start with clean power to begin with so one isn't needed. Hopefully I would be able to plug in the Evo, phonostage and TT because I can’t stomach buying two of them – one for the Evo and one for the other stuff (and 2 of those would cost more than my Evo). I googled Running Springs Audio and not seeing anything recent for them and the company link was dead (unless a bad link). One of the P156 dealers has a 45 day trial period which is another reason I’m thinking more and more about one of those.

I’ll check out the panel later today and see what other stuff is on that side of the panel but not sure I will be able to do much about that – maybe we can move things around.

Thanks again. If I make any improvements here that are worthwhile I will update this thread.

Just read the last two posts before mine - thanks Jerry and skoc. It sounds like there may not be more to do. As mentioned above I may try a PSM 156 for the 45 day trial and see how that goes. Sinking a lot of $ into the new house though so this isn't at the top of the list (like room treatment is).

Have thought about battery backup and will take another look.

Wow. I'm shocked. (Yes. That's sarcasm.)

No, that’s not sarcasm.  That’s a pun.

There are power requirement "believers" and power requirement skeptics.  I'm on the side of the believers with the following caveats:

1.  You don't need an expensive power cable, just a heavy one.

2.  Many expensive power cables fail at condition1 above.

So I see why some of the skeptics treat expensive cables as snake oil.  On the other hand, some of the skeptics think you can size a power cord based on an amps normal current draw  This ignores dynamics and will generally result in disappointing results.

I recently bought a wonderful amp on the used market that there is a 2 year wait for new.  I was very happy to get it.  The selling included the aftermarket power cord that he had bought to use with it.  I looked it up.  It cost $300 and was 18 gauge.  I wouldn't even use that cord on a 15w streamer.  No wonder he sold the amp.

I googled the power cord that the OP uses and found paragraph after paragraph of flowery prose about it but never mentioned was the gauge of the wire.  Would you buy an amp that had 3 pages of description but wouldn't tell you how many watts per channel?

So my advice is to always use a heavy power cord (I use 10 awg, because they are easy to get).  Whether you use a $50 generic one or a $2000 high end one is up to you but make sure it is at least 12, preferably 10, awg.
