    I've seen a couple of harpists at Bigears. Mary Lattimore tends to do a lot of treatments on her sound. And Maeve Gilchrist played too, Celtic harp.

    I ran the Dirac room correction on the SA30 yesterday. The results were interesting, in a good way. The room is far from perfect and the sound seemed to be improved.
    In general I favor a neutral sound, the initial Dirac profile brightened things up a little. In preparation I had moved the speakers a couple of cm out from the wall and apart to the minimum recommended placement from KEF.
    I doubt if that made a huge change, more with the bass than anything. But the sound is 'better', I will go with that.

    Any experience with this?

    Why Your HiFi Audio System Sounds Worse on Some Days. Is this the Cure? What about Transformer Buzz?

    in my own experience -- can't speak for anyone else (including the dude above who goes off the deep end in meaningless adjectives IMO) -- I have noticed that the barometric pressure affects my stereo.

    On rainy stormy days -- what's that, "areas of low pressure"? -- my stereo sounds the best, very tight, very accurate, very "compliant." On sunny balmy summer days, the stereo sounds "looser" for lack of a better description. The difference is subtle, but consistent and weather-related.

    Can't explain why that might be so. It's not the speed of sound. Could it be that diaphragms move easier in low pressure?

I suppose I should just move everything inside........



    And buzzing in the power transformer? Pfffft. A $99 drugstore stereo is better built than that.

    Another factor, also subtle but reliably reproducible: if the stereo has been off for a couple of days, it sounds worse when I first turn it on, for a couple of hours.

    My guess(?) is that warming up the voice coils, by running current through them -- or possibly keeping the surrounds loosened up by exercising them? -- makes the speakers more accurate. To that end I've taken to turning on Pandora when I go to bed at light, and closing the music room door (which is pretty much sound-proof.)

    I was interested enough to click, but I had a sense I could not trust the way the site responded, so I stopped.

    What were their conclusions? Did they think fancy cables were snake oil or did thy feel there were real benefits??

    Alpha-audio is pretty serious, no worries. They tested 32 cables, measuring and by ear, one of them ordinary bulk cables from the supermarket, and there were big differences, and they describe them in easy terms.
    I just upgraded from NordOst Red Dawn, and I could relate to their description of this cable and to the 2 other cables I have heard or owned.

    But there are big price differences, and of course your gear is different from theirs, so the only smart thing to do, is borrow many cables and compare. If you don't hear any differences, borrow some other cables or save the money.
    I have been happy with all my 'upgrades' and it has been worth the money. I upgraded to NordOst Heimdall II (and off course I bought them second hand)

    Their conclusion was this:


    "One of the most important factors in speaker cables is impedance. It just has to stay low. Is has to stay low in order to keep the damping factor of the amplifier in good shape. So in this case: the lower the impedance, the better.

    One of the factors that plays an important role in impedance is inductance. The lower the inductance, the lower the impedance remains.

    A low capacitance – we learned when researching interlinks – usually ensures speed as well as stability in timing. However, it is often a game of balance between inductance and capacitance. It is virtually impossible to keep them both very low. So it is up to the manufacturer to find the right balance there. And you do that by playing with the geometry of the cable, insulation materials, types of shielding… et cetera. This of course requires the necessary expertise.

    How a cable handles noise is audible. Cables that show low noise in the measurements, actually sound blacker. That can – as with the interlinks – come at the expense of openness, looseness and ambiance. So, in this case, taste plays a role. And again: balance in a system.

    Finally, the phase differences in the cables. We have only been able to determine that there are phase differences. How this expresses itself in the reproduction is very difficult to determine, because we would have to compare everything with a fixed standard and do an A / B test for each cable. We did not do that."

    ^^ Capacitance alone can be a game changer. I had an instrument cable which made my guitar(s) sound muddy as hell. I checked it with a capacitance meter, and it was much higher than it should've been.

    This Saturday is the second month of two hours of vinyl listening at a local high end stereo store to demonstrate high end equipment by playing our records. This month is anything goes, that's a can of worms they may not be able to handle.

    I think everyone in this forum agrees.
    But I am in several HiFi-fb forums where many (to my surprise) begs to differ. I don't see the fun, but each to their own.

    Decent equipment can greatly enhance the enjoyment of music. My setup would never garner the respect of a true audiophile. But it's much better than what the vast majority have in their living rooms.
