Did Amir Change Your Mind About Anything?


It’s easy to make snide remarks like “yes- I do the opposite of what he says.”  And in some respects I agree, but if you do that, this is just going to be taken down. So I’m asking a serious question. Has ASR actually changed your opinion on anything?  For me, I would say 2 things. I am a conservatory-trained musician and I do trust my ears. But ASR has reminded me to double check my opinions on a piece of gear to make sure I’m not imagining improvements. Not to get into double blind testing, but just to keep in mind that the brain can be fooled and make doubly sure that I’m hearing what I think I’m hearing. The second is power conditioning. I went from an expensive box back to my wiremold and I really don’t think I can hear a difference. I think that now that I understand the engineering behind AC use in an audio component, I am not convinced that power conditioning affects the component output. I think. 
So please resist the urge to pile on. I think this could be a worthwhile discussion if that’s possible anymore. I hope it is.

@soundfield I am seeing libel and slander thrown around all the time. Read up on some legal precedent. I am not in the living room of MKR and have no way of verifying your relationship with him. Not one thing I said on this thread is fact. They are my stated opinions and a lot of other people thought the search was bs on asr. This is a forum not a news corporation saying the voting machines were tampered with. It’s my feeling and suspicion.

As I stated earlier no way I’d buy your speakers based on how you behave here and I’m not supporting Amir anymore. You both are what’s wrong with audio companies and dealers. The above is my opinion.

@texbychoice not only that but Amir himself profits from it by constantly promoting revel products. How do I know this? Well I once early on before I knew better was interested in his company and thought maybe I’d grab a pair of revels from him. He does exactly what he forbids others from doing. Allegedly. 

Am i the only one to defend psycho-acoustic and trained listenings over linear and time-independant set of measures ?

Subjective and Objective Evaluation of the Acoustic Vacuum-Tube Amplifiers

 
Document Thumbnail

The subjective and objective evaluation of five high-quality vacuum-tube audio power amplifiers is presented in the paper. As the reference, a professional transistor amplifier has been used. The subjective evaluation has been done by a team of judges, as well as using a computer-based psychoacoustic model in accordance with PAQM protocol. The amplifers’ sound quality assessed by the listeners is consistent with the one evaluated with the use of the psychoacoustic model. It was found that the best sound quality is obtained by vacuum-tube amplifiers, the worse – by the reference amplifier. The results of subjective evaluation are inconsistent with quality assessed by measurement of objective parameters: all amplifiers have comparable quality but transistor amplifier is the best one due to the lowest THD+N level.

I'm willing to bet a dollar that John Atkinson didn't trash that Luxman tube amp because, like David Manley, he understands that such distortion levels (a) may not matter (audible or inaudible) to the human ear; and/or (b) may sound pleasing to the human ear.  There's a big assumption in the ASR conclusion that the Lux is a bad amplifier--just as there's a big assumption in the ASR conclusions that some other amplifiers are deserved of a golfing pink panther. 

And as @mahgister as adroitly pointed out, is this science?  The assumption calls into question the use of label "science review".  

Personally, I'd love to walk into a room with a pair of 100dB speakers and hear that little Lux churning out a half watt of sound! 

Mr. Atkinson's write-ups just sound more scientific and don't have schtick.  I prefer them. Others may prefer ASR.  It's free country.  I just hope ASR helps people on their audiophile journey.  It doesn't work for me though.

 

 

@jbhiller I agree with you. It occurred to me that the speaker that Amir used to listen to the little Luxman amp was entirely inappropriate as well. This reminds me of the poor review that Jason Victor Serinus wrote of the Jadis JA200mk2 amps for Stereophile, wherein he mismatched the amps with his virtually impossible to drive Wilson Alexia’s! Instead of blaming a mismatch of gear, which frankly was obvious to anyone with any experience in this hobby, he places blame on the amp/victim.

Ever since this review, I read JVS’s reviews with a grain of salt and suspect he really is somewhat unqualified to be in his position.
