  1. We say the word ‘impedance’ as if it has its own unique meaning. But? Just thought….. Was the technical term “impedance” invented to describe (through using a determined system for measurement) how a signal will be impeded? How much it will be impeded (hinder, obstruct, hamper)? Hence… stated ..”like a resistor?”

    1. Yes, exactly. Impeded in the same way a resistor resists. Good detective work, sir.

      The difference is this. A resistors resists at all frequencies, while an inductor impedes only at specific frequencies, which is why they are used a lot in filter networks.

  2. If we can’t find specs for our equipment, what is the best way to measure this? Can we just use a digital VOM and test at the inputs or outputs while the unit is unplugged?
    (And we love your rambling, it’s what keeps us coming back!)

    Thanks,

    Eric M.

  3. Hello Paul,
    I have McIntosh MC7300,Input Impedance 40,000 ohms, I try use McIntosh C46, Output Impedance 480 ohms.
    But get very poor sound, the midrange is too prominet. Do you have a good idea,please let me know,thank you.

  5. We are all from the same group, HUMAN BEINGS!.. Everything else is a sub-group. Personally, I do not care what anyone believes, no matter how radically different than my beliefs provided they do not insult or harass me for my beliefs, or try intimidate me into changing them, and their beliefs do not negatively affect me or others. I guess you might say the beliefs must be benign.

  6. Paul’s putting people in boxes again !!! I’ve been in the KISS box for the last several years. It’s nice and cosy and is good for my electricity bill.

  7. Due to its oftentimes lack of palpability, audio is possibly the most controversial and dogmatic discussed matter (in theories) with on the other hand the most common practical agreement on what’s good sounding or not.

    Place a digiphobe and a vinylophobe, a tubophobe and transistorphobe, a Class A and Class D phobe etc. in a room and play different setups in a blind test scenario. I bet, they all prefer the same when it gets closer to perfection. They just make different compromises until a certain grade of perfection is reached.

  8. It’s human nature to judge others by our own abilitys, experiences etc. In short we tend to think others are like we are until they demonstrate they’re not. A thief has more locks because they think everyone is a thief. Personally I’m glad differences exist. Wouldn’t the world be a boring place if everyone was the same.

  9. For me (audio) live is simple, but not too simple.
    – love cd/streaming
    – don’t like vinyl
    – love thoroughbred class A/B SS amps
    – don’t love tubes (except the ones underground)
    – cables from €100 to €2000
    – components/cables from USA, GB, Holland
    – tv, bluray from Japan
    – have multiple locks, but am no thief
    – don’t like flat Earthers
    – don’t like digiphobes
    – don’t like people that live in the past (e.g. music taste !)
    – would like to have "More-Money-Than-Sense"; alas, it’s the other way around…
    – love a lot of jazz, rock, classical symphonies, bands, singer/songwriters
    – love Beethoven, Liszt, Brahms, Chopin, Bartok (composer as well as the dCs dac/streamer)
    – don’t like Mahler, Bruckner, Wagner, Bach
    – don’t like blues and country
    – don’t like dance, hate ballet
    – love tennis, volleyball, (real) football (you know, what Americans call soccer)
    – don’t like rugby, American Football (you know, where the ball is played with the hands most of the time…)
    – don’t like icehockey (you know, what Americans call "hockey"), basketball
    – hate stupid sports, e.g. curling, cricket, korfball
    – love chess, don’t like bridge (except the one in my PSA DSJ).
    Okay, that’s enough confessions for one day ! In fact for the whole year.

  10. The only thing I know for sure is that it takes a wise and patient person to interact with people having differing views.
    Tolerance is an indicator of experience and understanding.

    Years ago I concluded that I am happiest when the person with whom I am interacting feels better about themselves following our interaction. I want to nurture and teach, NOT obliterate the other poor soul with my genius. 🙂

  11. All the qualities the post describes are based on personal experience. Some are based on objective evidence and some on more subjective feelings. Imagine a person with no opinions at all. Terribly boring. As long as people indulge in civil exchanges it is great fun. Disagreements are very welcome. No verbal Donny brooks. More the merrier. Your posts are great because everyone is welcome to give his or her opinion. Many are quite educational. There is always room for improvement in every one’s life. Keep up the good work. Regards.
