    CD is better than vinyl, which is why vinyl sounds better than CD

    Nice simple argument, but although seemingly logical, it largely misses the point. The kind of music you say sounds better on vinyl is not the kind of music audiophiles listen to. You state that much jazz and classical music has not suffered the same compression as pop music. So what explains the audiophiles preference for vinyl?
    The two examples you site no audiophile, or most other serious listeners would consider worthy of vinyl. Most vinyl lovers, love it for the unique sound, nostalgia, ritual or because it's cool, or a combination there of.

    My latest infatuation - transformers

    Yes - 'just to find out what happens' is exactly it. Curiosity I find is a totally relentless master No sooner have I gotten some cost out of the system than I'm again asking 'do I really need this part?' or 'if I substituted Y for X would it still sound this good?'

    Active speakers with electronics inside though I've just about had enough of. I'm planning to move the electronics out of the speaker cab so that tweaking can be done much more interactively. The more tweaks I can try the faster I'll learn what's important

    More good stuff ... in one way it's just downright more interesting, prodding and pushing supposedly unpromising gear to deliver competent sound - one has no hesitation in butchering things, just to "see what happens".

    And the satisfaction in getting a cheapie to deliver is ...

    Repair of a vintage driver (Richard Allan)

    Yes, the repair worked well. It is back in its box and running.

    I have repaired a number of speakers over the years, recons are straightforward if fiddly. The hard ones have been old drivers. One real challenging one was a wharfedale driver with a burnt out voice coil.

    That one I had to cut the original voice coil out and make a new one. I might have been able to buy one (it would have saved me a lot of fiddling if I did!) but in the end I mad a mandrel and wound one myself.

    It took three tries to get one the right diameter, and I am sure the power handling has been compromised by me using a post-it-note as the paper coil former. But the motor assembly now runs well.

    Then I found that the magnet needs to be recharged.... so back into the repair queue with that one!

    When I was married (going back now a decade and a half) my wife remarked I was one huge wooden spoon.... Seems we're cut from the same cloth. Yes let's wait and see

    My latest infatuation - transformers

    When I was littl'un, we lived way out, in the bush, as we call it here. And I used to visit big ants' nests, where they were scurrying around, calmly carrying out their everyday activities - and I'd pick up a big stick, and poke it down the big centre hole of the nest, to see what happened ...

    Hmmm, don't know why I just mentioned that ...

    Ummm, ahh ... yes, bit of a shame, but will see how things develop, .

    I was curious about Mooly's 'loaded opamp' test, tried to download the files but seems in China, dropbox is blocked so no cigar. Elvee has posted up an interesting way of doing a difference, one I'd not considered before - using LTSpice to subtract the .wav files.

    So far everyone is talking about the distortion but in my experience, loading the opamp sags the power supply dynamically and I wonder whether that's what Elvee's found with his cursor on the waveform? All very interesting stuff

    I see you're on the case with Audacity already - excellent progress!

    Later - looks like your analysis got the tumbleweed treatment too, in favour of Pano's
