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.

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. 

 

 

I need a power conditioner with 12 outlets. Seeking new and my budget is $4000.00 maximum. The only one that I have seen thus far is the Furman IT reference 15 amp version for $2500.00 retail. The Furman has a total of 11 outlets. It also has an isolation transformer. Does anybody have any experience with this item or anything else that might work?  Thank you.
