  1. No problem. Japanese uses all 3 character sets. You can't learn Japanese without knowing all of them. Hiragana: ひらがな Katakana: カタカナ Kanji: 漢字 There are about 50 of the top two, and 6000 of the last (though only 2300 are in common use.) Kanji are basically the Japanese adopted Chinese characters almost unchanged. If anyone's looking for a lockdown project, learning Japanese will keep you going for, oh, a lifetime?
  2. Yes I do, it's impossible to know Japanese well enough to translate it without knowing kanji.
  3. Square waves like those require ultrasonic frequency reproduction and are not representative of the audible frequency range. Whether that's important or not is a debate in itself but that's why I specified the audible range before.
  4. That's most interesting, and contradictory to what pretty much all other measurements have shown. You usually need to get to coat hanger quality wire or below before anything shows up visibly on a CRO to audible range frequencies.
  5. CRO showed what signal was cleaner, and how?
  6. John's implying I'm deaf here, which he has a habit of doing since we disagree about the effect of power cables, and whilst it's no secret I now have a hearing issue, it only developed last year and my crossover capacitor experimentation all predates it. My main issue with these caps is you can get 1.5uF of copper paper/poly foil caps from Miflex for the same price as these 0.01uf caps. Such a large bypass value has massive effects in my experience, and allows you to have 10% of the total capacitance bypassed for a more affordable price. No, they're not silver foil, but they're similar construction and there's 100x more capacitance and that much bypass effect is unquestionable. I've not had the pleasure of hearing the cast silver caps from Duellund in full sized values, but the cast PIO copper were equivalent to the Miflex in my experience.
  7. That still makes The Duellund bypass .01uf caps less than 1% of the total capacitance.
  8. That's what I've been getting at. Unless your base caps are small, I can't see how these can help, but some people insist they're getting fantastic results even bypassing large caps whereas I haven't found they do anything when they're less than 1% of the total capacitance.
  9. That's a much bigger bypass than mine. Mine were to 9uF and 80uF caps.
  10. How big are the tube buffer coupling caps, and what type of cap are they? Perhaps it's because I was already starting with high quality MKP caps (midrange) or even polystyrene film and foil (tweeters) to begin with, and the step up wasn't as big? Moving to much larger value copper foil in paper caps as bypass was a marked improvement by comparison.
  11. Only since you asked, I did not. I couldn't hear any difference at all when I tried them in speaker crossovers to either my tweeters or midranges. I've only heard differences when the bypass capacitors I tried were 10% of the capacitance instead of .1% as these are.
  12. Now if you decided to use a push pull amp with more power for the woofers it would be a different story.
  13. It's impossible to know in advance whether one interface is better than the other on your particular equipment. However, it is not uncommon for optical interfaces to not be as good as coaxial ones because of the extra interface of converting the signal to optical and back again, even if the optical transmission itself is lossless. If you are on a tight budget, I would recommend any affordable true 75 ohm coaxial cable instead of a fancy audiophile brand. These can be purchased for less than $20.Something like this is perfectly fine: https://www.selby.com.au/brands/isix/isix-quality-coax-digital-audio-cable-rca-rca-iht8801.html It is both 75 ohm and well shielded meeting virtually all the requirements of a true coaxial digital cable. I use something similar in my very expensive hi-fi.
  14. I believe you're confusing biwiring with biamping.
