  1. Remarkable, yes. But not unpredictable! (Paragraph 2) cheers Grant
  2. Cool. So in that case, and knowing that sighted listening is so unreliable as a means to learn anything much about sound waves, how is one supposed to form an opinion that an expensive turntable’s sound waves are worth even one dollar of that vast sum over a competent modest turntable? You see, I have been quite scientific all along. For it is a correctly scientific approach to gather whatever best information is available, whether perfect or imperfect, form a working hypothesis from the information, and then run with that hypothesis until better information arrives and disproves
  3. And what is the path to actually forming an evidence-based opinion on the subject, @muon*? That’ll straighten out the ‘circle work’... cheers Grant
  4. Hi muon*, didn’t the irony of your words spring out in time, given the entire point and topic of this thread? ☺️ cheers Grant
  5. My Guru vs Your Guru — so this is where turntable threads go to die. 😆😆
  6. Hi Rocky500, I am ’sciency’ enough to know it isn’t perfect evidence, and ‘mathy’ enough to know how much more evidence it is than the zero evidence that Aprilsnow provided 🤔 along with his or her 100% unequivocal claim. 😏 And yet you chose to question my statement and not his/hers... cheers Grant
  7. Hi Aprilsnow, the OP provided evidence that contradicts your claim. Can you support your claim with equally independent, verifiable evidence? cheers Grant
  8. Thanks @almikel, I should have said, "it doesn't matter which of the recommended positions I put it in", which I did. It was at the null location on the side wall. Also, I was quoting a comment by Dave about locating, by ear, where the sub is, and in that context, the literature seemed to say it doesn't matter where it is placed, you won't be able to locate it by ear when the crossover is around 80 Hz. I have also used EQ since day 1, which is considered mandatory for sub bass... but really I thought we were talking about locating it by ear, and that was what my story
  9. Hi Dave, When I bought my first subwoofer, I thought, knowing the literature, it doesn’t matter where I put it. So I put it on the side wall directly to the left of where I sit. About 2 m from me. Set the AVR to 80 Hz, adjusted level and delay, and started playing music. Now, I’m not saying I could localise it, but my left ear felt more ‘pressurised’ than my right ear. You know that feeling that makes you want to hold your nose and ‘push air out through the ears’ to get rid of it? Can happen when you drive up a hill? Yes, that feeling. But only in the ear nearest to t
  10. Hi Rocky, thanks for the great story of your personal audio journey, I love it! 🙂 It brought to mind John Atkinson’s journey story, very much the same story, if you substitute your Emotiva speakers with his Quad 405 amp in the 1970s. However, JA misinterprets his story as a lesson in how DBT can’t detect differences in the sound waves, and sighted listening can, which is a mistake. What sighted listening does is create experiences, other than what is in the sound waves, from non-sonic factors that become dominant. We can enjoy the heck out of such experiences, and the
  11. Hi MLXXX There are two problems with the pivoting tonearm that a linear tracker solves, and the pivoting headshell only solves one of them. It solves the problem of making the needle tangential to the groove rotation, but it cannot solve the problem of skating. The latter is actually the bigger problem. Skating has a static component and a dynamic component. Anti-skating mechanisms only address the static component, and, when perfectly dialled in, only at one point across the record surface, because the static component varies with groove speed. The dynamic component is
  12. Hi Rocky the key thing about the sighted listening effect is that it is unconscious. By definition. Hence, the idea that we can consciously know how it will work, and hence know whether it was ‘in play’ in a specific listening experience, is unrealistic. Just because you consciously like DIY and cheap boxes, will not dictate what happens unconsciously in sighted listening. It is an unconscious process. I fully understand how you are rationalising a belief that you have escaped the clutches of the sighted listening effect, and how you think it really must be
  13. Hi John, from Archimago’s article, “The samples were all ripped with the same ADC (my Creative E-MU 0404USB) and laptop (Acer Aspire 5552-7858) using Audacity 2.0.5 at 24/96 bitdepth/samplerate.” Whew! As for your Cobalt DAC, from ASR’s review, “I don't know how they consider 6 dB droop at 20 kHz acceptable.” That’s amazingly poor design! Amir concluded, “Whoever designed the headphone amplifier in this product needs to go back to engineering school or pay attention to what the competitor is shipping. Actually he needs to do both....it fails in so
  14. Hi gumptown, I predicted to myself, when I read your OP, that would happen. It is a common reflex action by those who spend relatively large sums on turntables, and have confirmation (sighted listening of course) that they are audibly improving the sound waves, sometimes in significant leaps and bounds. I have only gotten as far as your post above, but my other prediction is that you will attract a fairly robust dissection of the blind test you mentioned. Not only of its specific controls and design, but of the fundamental usefulness of the blind test as a means of dete
  15. Hi El Tel As well as your excellent points on recording compression, DR Score jumps up and down with:- The music itself. I reckon some music would score a 1 or 2 even with a perfect uncompressed recording, or if it were possible, even measured directly off the live microphone feed. Making mastering adjustments that have nothing to do with the dynamic range or use of compression. I once saw a video by recording engineer Ian Shepherd, where he took one of his own masters and mixed some of the bass to mono (a la LP mastering), and the DR Score jumped up by six.
