    Smile DIY amps

    Hello people

    I was wondering if you build your own loudspeakers/headphones pre/amplifiers.

    I'm a telecommunications/electronics engineering student, so, as you can imagine, I've already built several of them, class A, class B, some hybrids between those that each one names as each one wants, with/without feedback, with transistors, valves, both (, and none )...

    There are 1000s of designs available on the internet, and specially for preamplifiers or low power amplifiers, one can use a wide range of analog integrated circuits which work incredibly well.

    Currently I'm researching about power supplies, which most of the times is the main factor on the disgusting NOISE, and the main factor of my projects, all of it below the price you eat in a normal restaurant

    So, as I haven't seen a post for this, I'm opening it

    Greetings!

    Haven't built my own, but have purchased one that some fellow built himself, and I quite like it
    I have a minor desire (as in, somewhere after learning how to play the piano) to build my own headphone amp.

    Have you noticed that food tastes better when you put an effort on cooking something complex for yourself?
    Can't compare to food made by a professional (mother ), but anyway it somehow tastes better.

    I think same happens with a simple A-class low/medium power amplifier, somehow it sounds better if you build it yourself, hehe.
    You can get professional results for a few dollars in low power, and if you're good designing or soldering, you can get professional results in whatever power

    For the last five years I have listened to a pair of Cyburg's Needles with Visaton FRS8's. Having now moved house and got them in a small room where I can have them right in the corners I am again amazed at how good they sound. So much so that I have ordered a pair of Tangband WS3-871's from spectrumaudio.de these are supposed to be a lot better than the Visaton ones.

    These are driven by a Gain Clone with a pair of 160VA toroids and two LM3875's.

    A bloke in Canada is selling Needles with Fostex drivers, they are very versatile, for 1,800 CAD

    The Gain Card amplifier if bought from Mr Sakura in New York would cost;

    $1,650 x 2 for the Gain Cards
    $2,000 x 2 for the Power Humpty's (power supplies)

    So thats $7,300 plus $1,756 USD for the Needles = $9,056 or £6,135.

    To find the Chinese factory gate price of most items, I used to import stuff, divide the price by 8.

    To find the cost of making the above yourself divide by 34.

    Not only does doing this save money you can also learn new skills that may be very useful.

    See a bit more on these two pages I put up;
