Seeking a Power Conditioner


My system consists of the following:

  1. Martin Logan 11A Impression Loudspeaker (hybrid)
  2. Bryston 4B3 cubed power amp-300/channel into 8 and 500 into 4
  3. Bryston Bp-19 preamplifier
  4. Chord Qutest DAC with S Booster Linear power supply
  5. Lumin U2 mini streamer with LHY Linear power supply
  6. Read reviews on both Niagra 1200 & Puritan Audio PSM 156 power conditioners and the reviews were extremely positive. While reading I came accross a review of both products by Audio Science Review (ASR) who claims his reviews are objective with scientific data supplied and his reviews were not nearly as positive to say the least. Anybody have any thoughts on how I should proceed with the differing of opinions.  Thank you.

First of all with your system, I would recommend a Niagara 3000 or 5000. 
As far as ASR, there is a lot of Kool-Aid being drank in this hobby. He drank some pretty weird Kool-Aid.

Two direct lines... 10 gauge, one for power conditioner and all components except amp. Amp, directly into wall.

Look at the best Shunyata or IsoTek you can afford.

@gkelly +1 Pay absolutely no attention to ASR.

+2 for pay no attention to ASR.  As far as power conditioning is concerned there is a controversy sparked by misunderstanding.  It is only needed in locales where the power supply is not tightly regulated or in areas served by old infrastructure or where a recent increase in population has resulted in a power demand that is taxing the power grid.  Not everyone needs power conditioning and if it isn't needed it does no harm, but it does no good either.  Hence the confusion.  I live in South Florida and in the summer months in densely populated areas the voltage swing goes from ~105 to ~120vac.  Especially during peak usage times this can affect audio performance.  I use a PS Audio P20 and it smooths things out completely.  I don't have to fuss with the bias on my tube amp any more and tube life is greatly extended.  That is real world experience over the past 8 or 10 years. 

ASR writes fiction to attract clicks.

That said, have you ever seen a negative review (except the clowns at ASR)?

Neither of them would be on my list.

Go with a regenerator.

Have a question about ASR. reviews. I have been into this field for about 40 years and believe that each piece of the puzzle makes a difference in what we ultimately hear, room treatments absorption, diffusion etc. cables and interconnects, power cords, amps, preamps. dacs, streamers, etc. I have always believed reviews whether from magazines or fellow audiophiles are credible. Of course, I attempt to listen for myself before making a decision. For example, I plan to purchase the Schiit Loki Max, based on reviews.  Now I come to the issue of power conditioners.  I currently have a Richard Gray conditioner that is 20 years old or more.  I wanted to make a change on the rationale that conditioners have improved technology  since my purchase. My goal is to reduce the noise floor so I can listen to music at 55 dbs and still hear the dynamics and full body of the music. In my quest, I figured that less noise, more music. Then I read a few positive reviews in print and was ready to make a buying decision, until I came  2 reviews from ASR, who claims his tests are conducted with objective scientific instruments, and he concluded that 2 specific conditioning products  that I already mentioned make almost no difference at all as to the goals of reducing the noise floor or otherwise.  On this site, a few people have said his supposedly scientific testing is not useful, and that the subjective reviews online and in print have more value as compared to his objective tests. Are the conditioners for real?   Who is correct and what is your rationale for your conclusion? Would appreciate any thoughts that you may have.  By the way, my budget is in the $3000.00 range, new purchase only. Thank you.
