  1. Hat still firmly in place: For a given speaker, power does equate to loudness. A speaker's efficiency is measured in dB per watt. 

     

    That dB/W rating varies from speaker to speaker of course, so 10W through an efficient speaker can be as loud as 100 through a subwoofer with a heavy cone. 

     

    To be clear, I'm talking about the watts the amp delivers into the speaker, not the amount of power it draws from the mains. A mosfet based class AB Trace, for example, is a lot less efficient than a modern class D so the power rating on the IEC inlet isn't an indication of its ability to be loud.

  2. Gday

     

    After many years of playing exclusively fingerstyle, I now want to make the sounds that Steve Hanley, Tracey Pew and Kim Deal do (did) so well. I have the Precision, the Ampeg and the round wounds. 

     

    All i need now is someone to teach me how to use a pick... Help! 

     

     

  3. Pedant hat on: Watts *does* translate to loudness. It's just that Trace's power rating is a tad more conservative than that of Brand X, which usually has as much do do with the marketing department than the engineers. 

     

    Pedant hat off: he's right though, treat power ratings with scepticism and bear in mind that 200W is only 3dB louder than 100. 

     

     

  4. Hi Phil, if it wasnt you that recommended the imaginary* paint I was thinking off, I dont know who it was. It's for my build of your Fane 8" beast.

     

    *must be a pigment of my imagination...

  5. Thanks, all.

     

    I'm sure the one i was recommended was available in smaller quantities... and it had options of glossy or matt, matt being more camouflaged for theatre applications.

     

    A kg of tuffcab would last me several lifetimes!

  6. Good day.

     

    Someone here recommended paint for cabinets that you apply with a roller, and it comes out like Tolex. Sort of Hammerite for wood.

     

    I made a note of the brand but unfortunately I wrote it on a pie which I later had to eat. Can anyone remind me?

     

    Thank you.

  7. What Bill (and to be fair, mostly everyone else) said.

     

    My theory: https://en.wikipedia.org/wiki/Veblen_good

     

    "A Veblen good is a type of luxury good for which the demand increases as the price increases, in apparent contradiction of the law of demand, resulting in an upward-sloping demand curve. The higher prices of Veblen goods may make them desirable as a status symbol in the practices of conspicuous consumption and conspicuous leisure. A product may be a Veblen good because it is a positional good, something few others can own."

     

    Plenty of this to be seen in hi-fi. And, lately, bicycles.

  8. That's definiitely a faulty amp. 

     

    The source of the noise might well be on your mains, but in order to earn its CE mark the design must have passed a test in which noise is introduced into its supply and isn't affected by it. Similarly the amp must not emit anything that might upset your TV or pacemaker. 

     

    I wonder if it's just an intermittent fault that makes it behave in the shop. It'd have to be a pretty big noise source to affect it that badly and nothing else in your house seems bothered by it.
