Main Stream, from Vera-fi Audio

I just bought two but won't have them for a bit being in Canada they are shipping out next Thursday.  I have two Puron filters which will go into the 1st positions in my Audiece R12 conditioner.

  One mainstream will go into the outlet the Audience conditioner plugs into, the other Mainstream into the outlet my amp plugs into. Looking forward to getting them and will report back later on.

  There are two positive feedback reviews.

@sgordon1  Did you have Puron's or another brand of plug in conditioner before the Main and if so how do you contrast them?  I'm particularly interested in your experience if vs the Puron.

I started with a Puron in the power conditioner and in its outlet at the wall.  Adding a SnubWay, in the first position of the pc, was a good move.  Replacing a Puron (at the wall) with MainStream was really a giant step sonically.  MS just is more “powerful,” it does so much more...  It’s as if you had a list of all the positive attributes you wanted to hear, and then could “check every box,” simply by inserting MainStream.  I’m waiting for delivery of two more.

Here is the follow up Positive Feedback review with a link to the first review

Stereotimes review while I wait for my two Mainstreams to arrive.

I’ve got a Snubway with another on order. It seems that the Snubway and Main Stream address two different areas of the audio spectrum. The Main Stream appears to deal with line noise from household components as opposed to switch mode noise from audio system components, like the Snubway.

Does this item require a burn in period?

@ozzy ... burn-in is approximately 10-12 hours.

rib61,

Thanks.

Is that burn in time for the Mainstream unit to develop, or is it the time to work conditioning through the system AC.

 I have had the Mainstreams for a while now. Prior to the Mainstreams arrival I put the two Puron filters in the first position on my Audience Adept Response r12 conditioner.

   One Mainstream went into the wall receptacle that the Audience conditioner is plugged into and the other mainstream went into the receptacle my amp is plugged into. Prior to getting the Mainstreams I thought my noise floor was as good as it gets , I was wrong on that. 

  The Mainstreams have added resolution and clarity better than before. I was very surprised.  You can Cleary hear more detail in notes fading out , etc as well as everywhere else. I always use Mobile Fidelity - Beck Sea Change for critical evaluation.  There's so much going on in the soundstage. Notes within the soundstage clearly stand out within their own space more. 

  I would totally agree with Ozzy's comment in his review of a more defined center image and real. I must say it was a pleasure talking to Mark again. I like your enthusiasm. 

  There is a 30 trial period , if you are not satisfied simply return them. Mine are staying put. For the increased resolution,  clarity, soundstaging etc, the Mainstream is a bargain for what attributes it will bring to your system.

Many thanks here for the fine comments.

Main Stream and SnubWay are good examples of what CAN BE DONE re Noise for reasonable dollars

My favorite part is your system remains as it is. These plug ins do not change the nature of your systems sonic signature per say... They do their job re Noise which yields something much greater

Thanks again

Mark
