  1. At one time that too! I find it amusing that digital is being blamed for creating the phantom images in space. That what is suppose to do.
  2. The whole purpose of stereo is to generate the instrument/vocal in space.
  3. Focus in between the two speaker. That's the biggest difference that maybe responsible for our liking for vinyl, IMO. OTOH, I have seen "experts" who couldn't distinguish digital and vinyl without side by side by side comparisons. Recording is not by me. High end playback for both digital and vinyl. LP vs CD. A blind test.wav
  4. Bass and treble will do the job just fine.
  5. Thanks. I am okay with correction and I think it is a necessary evil. I always believed it was the conspiracy of the high end propagandists to do away with the most basic correction tool, i.e the treble and bass, which would make most equipment to sound almost alike. Of course, that’s not healthy for high end market. I need more more time to digest your approach but on the surface I agree to your approach.
  6. FM response is the response inside your ears which transforms the flat response that reaches your ears. We already taken the the FM curve into consideration since birth and adapted to the sound to interpret them as flat or bright or dull based on the FM curve. No reproduction system should ever try to recreate the FM curve because that would again transform based on the natural FM curve inside your ears. This is is not the first I have seen because I know of audiophiles who use paraEQ to change the output from speakers to represent the FM curve. I am not really following what you are saying because it looks like you have software which actually transforms the supposedly flat FR from a perfect system to be curve like FM response. Having said that, it is normal to have one preference over the other which is subjective and inconsistent. The actual correcting would have made them to bright. A common most act by recordists who uses binaural recording to play them with loudspeakers without correction.
  7. So you believe that correcting the FR so that the curve is somewhat closer to Fletcher Munson curve?
  8. And how do the measurements made at “the fully developed” spot is useful to the one who believe that measurements of speakers determine the preferred sound? Are the listeners going to sit at the exact distance and turn his room to an anechoic chamber? You do not know the variables to have any meaningful interpretation of the speakers measurements. There was a disputed between Harbeth and Stereophile when the measurements of Stereophile did not agree. Measurements varies as the standard/method is not fixed. I don’t even want to get why there need a specific distance for the sound to be fully developed or what happens outside the particular spot. Or why the speakers sensitivity is quoted at 1 meter distance if that’s not the spot where the sound is fully developed. In the end, whatever information you get from reading measurements of the speakers provides no constructive information that will be useful. If I am not mistaken, once Toole said that you get better information information from a tyre specs than the manufacturers speakers measurements. Not to mention about AES papers on objective and subjective evaluation of loudspeakers to address how to get useful measurements to judge speakers correctly. I have stated my position and nothing further.
  9. When you are done with it tell at what distance they are measured.
  10. What a wonderful opportunity. It would be great learning experience if you had made a binaural recording of your reference track at LP of the TAD and compare them with the subsequent recordings with Wilson and tuning progress. It it may not be useful for others but the recording would provide a reference to you and know where you were heading towards the perfection. You will have instantaneous AB comparison and can always revert to a particular setup based on which one of them really sounded good to you despite what the measurement says. Just sharing my opinion.
  11. Since you are talking sense are you ready for 6) I can post charts of many different drivers and I salute anyone who could predict the sound quality of the speakers based on these measurements. ?
  12. 1) Frequency response is usually taken at 1 meter. 2) very few people listen at that distance. 3) cone material is also responsible for the production of harmonics. Any vibrating material will have its own resonance. Tap on a paper and a poly cone. They produce their own sound. 4) As Emcdade said, the response is irrelevant when we consider how the two sound waves are processed by the ears compared to a single measurement of a microphone. A slight movement of the head will dramatically alter the peaks and dips at LP. 5) Flat response at LP is the overall sound and not the Flat response of the driver/ speaker. At LP the Preferred FQ is generally flat. This can be very different compared to what’s measured at 1meter and at LP. 6) I can post charts of many different drivers and I salute anyone who could predict the sound quality of the speakers based on these measurements. 7). Our ears are hardly linear and whatever measurement you get from the measurement changes dramatically inside the ears. Hence, the differing preference of listeners despite what the FR says.
  13. You can do this with DSD recordings filtered at 20 and 50kHz. The ultra freq can have a positive or negative effect. There are research on monkeys where even a short exposure to these ultra sound can have lasting impact to them.
  14. I use CrownXLS. For your need the 325watt model is more than enough. https://www.crownaudio.com/en/products/xls-1002
  15. Maybe you can start to have some guidance from links like this http://stereobarn.com/how-to-connect-a-stereo-system1/ so that you know what to get within your budget. If you are only interested in music then the source connected to int amp which will be connected to the speakers are more than enough. If you want to enjoy music and movie with good sound then the best way is to go is receiver. Unless you have a dedicated room for audio or video, the current receivers are good enough to satisfy most music lover in a typical living room. Integrate amp is power amplifier and pre amplifier mixed in one. A good second hand receiver is good enough to drive the Cambridge speakers. My advice is to save first so that you can buy the speakers at the same time.
