    learning to listen

    Useless article
  2. Somewhat Would like to try high-efficiency, fully time-aligned speakers Try dnm amplifiers - move away from all the metal-clad behemoths Upgrade to the TX2 and DA2 Upgrade to better ST optical cable? Send in the ELP to get it upgraded with wood body chassis and enable the 78s playback. Try the TOTL Tom Evans Phonostages. Change cables to dnm with plastic terminals
  3. You forgot to mention cable directionality. Tsk, tsk, tsk

    Yamaha RX-A3080

    I noticed that music sounds better when I switch the input to Phono first, then switch back to the actual input that I am listening to (whether it is balanced input from sacd player or Tidal). Use the app to do the input switching.

    Yamaha RX-A3080

    Downloaded some free quad dsd files to play on the A3080. I was surprised there was that much difference over double dsd. Almost felt as if blue coast deliberately degraded their double dsd files to make quad dsd more outstanding. They couldn't have, would they...? The surround ai mode sound really good.

    anti static

    Newly opened records or records that weren't thoroughly cleaned previously tend to have surface conditions that prevent water from spreading evenly over the surface. But this can go away after 3 or 4 rounds of just spraying water over the surfaces. When water is able to spread evenly over records' surfaces, those records often sound audibly better, and quieter. I dun brush during washing. Just spraying water while record is spun at high speed. The record is spun dried. No physical contact with other materials except water. I use combination of different water. Tap water for the bulk of washing. Bottled oxygenated water for "fattening" of sound. And tap water again for final sound conditioning. Records are consistently quieter and are more resistant to dust if the final rinse is with tap water.

    Clumping or without clumping, the resultant sound is different.

    I tried wetting agents to make water penetrate into the grooves better. The records didn't sound good afterwards.

    Yes, I realized that. Different water indeed does create different surface conditions. I noticed for quite a while already - tap water does a better job than bottled distilled water in creating dust-resistant surface, and afterwards the records sound more detailed, more opened, and more dynamic.

    Contactless wet clean, contactless spin dry.

    Vinyl romance?

    The writer says channel separation is important as evidenced by "...Anyone who has experimented with dual mono preamps, knows the advantages of the greater sound stage width etc that become apparent, with this approach and the benefits thereof, in terms of the perceived spacetial aspects...." Yet, twice, on this article he spelt out very clearly the limitation of channel separation with vinyl, and even worse, with cartridges. Someone, anybody, quick, better invent a dual mono phono cartridge!!!

    Amari RW-800 Record Cleaning Machine

    My friend just bought this for me. Collecting on Thursday Can't wait to try it on records....
  13. They could tell me the changes in imaging size and height with or without the handkerchief over the power cords.
  14. This was a test I did in front of listening newbies. I mean, they were hired as marketing audio systems, but most of them have very rudimentary listening skills - which is not a bad thing - because that meant their listening apparatus were still fresh, and they don't have any pre-conceived prejudice about what they can or cannot biologically hear. The test was: While listening to a piece of music played through a HiFi system consisting a DVD player, an av receiver, and a pair of floor stand speakers, I drop a handkerchief over the power cords. They can hear the difference. Then I remove the handkerchief. They hear the difference too. I tried a piece of velvet over the power cords next. They heard greater differences. Different fabrics materials coming into contact with power cords which have current coursing through them can affect sound! Why?
  15. Does the cj 350 power amp invert absolute polarity? Is it written specifically in the manual?
