Has a Power Conditioner Improved Your Sound?

Update

Sorry to say I returned the 707. After a week of concentrated listening I realized that what first appealed to me was actually an increase in midrange energy. It is a vivid presentation that in a way is more tube like. Everything is warmer, fuller and somewhat closer in perspective. This is a valid and euphonic sound. However in the end it's not a perspective that over time I found to my liking. It's most noticeable with Classical recordings. With the 707 I'm sitting in the first 5 rows. Without the 707 and plugged into the wall I'm siting in rows 10 to 15. I prefer that more set back perspective. You may like what the 707 does and it does do its job. The overall sound was slightly quieter but with the effect of a warmer midrange. Bass is slightly fuller and Strings more forward although still refined. So basically less air or atmosphere in the sound.

I'm not sure what I will do next. I've re-read a number of Power Conditioner reviews and it seems that the reviewers often mention that the lower treble can be more vivid or forward etc. So this may be a common trait of active conditioners. I haven't noticed this mentioned on the few passive conditioner reviews I've read. This included Shunyata and Furutech. In fact a review of one of the Shunyata PCs said the perspective was more distant. So maybe I will try one of those. But again I do not notice any apparent noise issues with my system but as I mentioned you don't notice it until it's removed.

Thank you for the update. Such is high end audio. It is really easy to like something at first only to realize something other aspect is amiss. I will admit that the 707 was a very budget oriented power conditioner. I looked at it and thought if the one I have in the bedroom with TV and good quality sound bar goes out I might get one,

I would look much farther up at Isotech or Shunyata. I’ve got a good quality 75 pound power conditioner I have had for over twenty years and each time I swap it out or compare it still is doing a great job.

Interesting turn of events. I am sure you were able to discern these traits of the conditioner by carefully listening. 
 

Now, I am wondering if the 707 will be a good fit for my home theater. It’s going to be the power conditioner for the AV rack. These will be connected to it:

1. McIntosh 7 channel theater amp

2. McIntosh 4 channel theater amp

3. McIntosh 2 channel theater amp

4. Marantz AV10 AV PRE/pro

5. Oppo 205 Blu-ray 

6. Amazon TV

7. Apple TV

8. Luxul Media switch 

9. maybe: Kaleidoscape

Tbe 707 will be fine for Home Theater. In fact its characteristics are more suitable to that application. A vivid, warmer up front presentation is excellent for movies. Remember it does provide surge protection, excessive voltage protection and lowers the noise floor.

Great feedback. Thank you.
