Report published: It doesn't happen often, but obviously sometimes it does – by mistake I deleted all photos I took during our meeting with Srajan. For two days I fought with my computer to recover at least some of them and I failed. Damn it! So I called Jarek Waszczyszyn, who in fact invited our guest from Switzerland, but I got nothing from him – he simply did not take any pictures at all. To be perfectly clear – nobody except for me took any photos during this CSS meeting – so there was nothing left after Srajan's departure except for our memories and some notes on piece of paper. Yeah, the piece of paper with a table filled in with all participants notes on what they liked and what they didn't when listening to different versions of recordings. I will elaborate on that in a minute, because now what seems to be much more important is a question that Jarek asked: what will remain after we are gone, what will remain after our civilization? Since deleting dozen of pictures takes only two seconds, what will happen if we transfer everything to the network? What if than this network (cloud is now more popular word I think) is gone, or it changes so much that it is not same thing as we know it today? Same question goes for all the content we put in the virtual reality today – photographies, books, magazines, movies, music, computer games and so on – basically most sorts of arts that not only make electrons flowing along synapsis in our brains but also touch the very essence of our humanity. So what will be left if all that is gone? As weird as it might sound most likely it will be the things that we stopped appreciate in this „electronic era” - paper, plastic, metal. Like this piece of paper that is the only solid evidence of Srajan's presence here – thanks to it we know he was really here, it was not just a dream. Also like Compact Discs, that were in fact the main topic of our meeting. SRAJAN Anyway – there are two main factors that tell us about how popular particular magazine is. And when it comes to the number of readers „6moons.com”, as far as I know, is an absolute leader with over 200 000 readers a month and 1 000 000 of site enterings. To give you some perspective – an American „Stereophile” prints 80 000 pieces a month (and please remember that this number includes returns and free samples), including 40 000 pcs in Chinese. British „What Hi-Fi?” - 60 000 pcs. And these are the biggest printed audio magazines in the world. Another British magazine „Hi-Fi News&Record Reviews” prints „only” 25 000 pcs. Polish Magazines print from 20 000 pcs („Audio”) down to 6500 pcs („Hi-Fi i Muzyka”). Can you see these huge discrepancies between what's printed and what's published on the web? Some of you probably saw and realized those numbers for the first time and it might have been a shock for you but that's how it is. Srajan Ebaen doesn't carry the first name given him by his parents, nor their surname, not even his wife's. He wasn't born in USA. Even though he runs an American magazine, registered there, kept on American servers, he doesn't live there anymore, although he did, for some time. We have Srajan „discussed”, so it's time for the main topic of our CSS meeting, that our guest took part in. We met to get familiar with two products of Japanese company Acoustic Revive:
So what are they? These are electric devices, the principles of their operations are based on solid physics and the results of their work can be measured. I wrote about RD-3 already some time ago – its a demagnetiser, that neutralizes magnetized iron particles, that are part of each paint, each plastic and so on. It's very important for Compact Disc as when spinning with high velocity it becomes kind of a magnetic field generator, that might influence a work of optic system that is moved by electromagnets. What's more – magnets, even so small as magnetized iron particles, might influence also servo mechanism and circuits amplifying signal right after they arrive from the lens, because when conductor goes cross magnetic field there is an interference induced in this conductor. When CD is spinning we might compare it rather with moving magnet (magnetized iron particles) but the outcome is the same. The purpose of RD-3 is to demagnetize all magnetized elements inside CD and thus to minimize their influence on the whole data reading circuit. What really RIO-5II does is much more difficult to comprehend, at least for me. This device looks like electric kettle, or a blender. You put a CD on top of it and push a red button. What's happening next? I need to quote a manual that says: „This will run the electric fan for 14 seconds, which irradiate the surface with natural negative ion on to the disc. RIO-5 II not only releases negative ion, it also emit infrared rays which works as a surface-active agent. This improves transmissivity of the laser beam inside the CD player, which leads to improved sound and picture quality. By using the RIO-5 II, it improves S/N ratio and dynamic range. All instrument and vocals become vivid and sounds fresh. On the picture, it gives depth and excellent color contrast..” Yep, for me it also sound like fairytale, but I still encourage you to read all the documentation HERE, this should clear up things a bit. Regardless of how well the whole concept is described, how well the issue of demagnetizing and deionazing is explained, there is still one simple question that remains unanswered – “does it really work?” METHODOLOGY That's why I organized a CSS meeting. Srajan was supposed to be kind of a „test-paper” (like Gerhard Hirt was during previous one), to tell us whether we had already totally lost it, or maybe what we were doing/hearing was still real/true. It was a simple AB comparison with unknown A and B. We took couple of pairs of exactly the same CDs and one of them was treated with both AR devices and the other wasn't. |
I handed pieces of paper with prepared table to all participants and they were supposed to fill it in with their votes – which presentation, A or B, they liked more, which sounded better, more live-like. I had a „master-table” where I kept the sequence of treated and not treated CDs plus I noted participants votes. It was a blind test – participants never knew which CD was played at the moment (treated or not treated). We noted the votes and discussed what we heard. The whole test was ran in Janusz system, who was a host of our meeting. This system consisted of : Ancient Audio CD Lektor Grand SE, Silver Grand mono power amplifiers, and First Generator; and also Sonus faber Electa Amator I (with modified crossover) loudspeakers; top Acrolink and Tara Labs cables; plus anti-vibration elements by Acoustic Revive and Base audio stand. CDs were demagnetized and Ionized right before listening to them. To verify efficiency of RD-3 and RIO-5II we used following recordings:
SOUND This is a part where I bring up statements of each and every participant, or I synthesize them to offer you only common output. Each time the way I chose depends on the kind of test we do and on the how the meeting in fact went. This time it seemed to me that offering you just common output/opinion makes more sense. That's because from the very first recording we listened to it was clear to everybody that the disc treated with AR devices and the one not treated sounded significantly different. We were all truly surprised. We repeated first three A/B comparisons couple of times so it was more of A/B/A/B/A comparison after all. We all felt that the difference was so significant that we wanted to be absolutely sure that it was a fact and not some group hallucination. As one of the participants said, I think it was Janusz, treating CDs with AR gave more significant change in sound than changing some cables in this system, maybe even more than changing one of the electronic elements. I did not feel that changes were that huge but I had to agree that they were significant, more significant than the impact of any anti-vibration elements, or cables we had changed before in Janusz system. The only change that mattered more was replacing 300B Create Audio for 300B Takatsuki (coverage HERE), but it still had not being that significant change. The improvements we observed here were mainly about basic sound and its harmonics being „better connected”. What we heard was more dense sound, with less treble, bit warmer overall tonality, and bit worse phantom images placement. I wrote that in Harbeth M40.1 test – resolution became better but selectivity worse. As at the same time there was bit less dynamics and all the elements on the soundstage were not so distinctly presented. And that's probably why opinions of participant were quite contradictory – just a reminder – I did not ask them to recognize when I played CDs treated with AR devices, but I asked which version they liked more.
Statistics comes first. We listened to fragments of 6 CDs and there were five of us. That gives in total 30 votes. And the final result was a perfect draw – 14 voice for, 14 against, and 2 undecided. That was another surprise as at the beginning we were all convinced that AR did such a great and good difference. And, in a way, we were right. Two last CDs we listened to were obvious winners for AR – we all managed to process the changes AR brought to the sound and most of us finally recognized them as good ones: there were 10 votes together and 7 were for, 1 against, and two undecided. Our meeting with Srajan was really an interesting and informative one. It allowed us to „see our reflection in his eyes”, to confront our opinions with his, and to learn how we all interpret what we hear. It turned out that we all, who cared for a good sound, heard sound in a similar way – it was the judgment of what we heard that differed us. That's why before you decide to buy RD-3 and RIO-5II Acoustic Revive for your system you need to check first if you like the changes they introduce – I can't tell you for sure that you will like those changes. I'd like to point out that the longer we listened to such demagnetized and de-ionized CDs the more right, correct they seemed to sound. Deep, rich, saturated, I might say „mature” sound does not happen too often. And the dryness of some systems built around clarity of sound and its dynamics craves for such a source of signal as CDs treated with AR devices. But our meeting also clearly proved that not everybody has to like the effect of that treatment – lesser dynamics, not so sharp images – all that could result in less open systems in a shift of tonal balance toward nasal effect. We did our job and now it's up to you to make a decision for yourself. P.S. A need of socializing, meeting other people is as old as our civilization. People can sit together around a fire, beer keg, TV set, stage or a pile of records – that does not really matter. We present our achievements, what we are proud of. We listen to opinions, impressions and we share experiences with other people. That's how the progress is achieved. If the proper conditions to exchange information exist – civilization thrives. Beginning of each civilization was always located near seaside or along some river – in the places where communication was easiest. Acoustic Revive |
