  1. I knew this when visited EDMW during lunch. I like his show very much.

     

     

    This seriosly shows the fraility of life. Faced with hundreds of dangerous/venomous snakes and hungry crocodiles, he didn't seem the least bit threatened. HOwever, When with this usually harmless stingray, he died. The odds are perhaps more than 1 in 10 000 000... This is seriously a wake-up tone for all of us. Your life may be over tomorrow.

     

    Worst thing is, you won't even know it... :mellow:

     

     

    That is why we must live everyday to the fullest.


  2. Hehe.. i am starting on bleach too!!! First episode yesterday on channel 56: 6:30pm. Interesting :D.. I am lazy to download so iwill watch the anime one episode at a time...

     

    There is some filler after 40+ episode. By then you'll get sianz. I didn't watch after the filler 'cos harddisk crash so dunno how good issit now.


  3. Hi ya. I am back after 2 days on the Battle Field (2).

     

    For the LED, giving it 5mA will be sufficient. Designing it to go higher would also means that your battery will go flat very fast. My recommendations is to use resistor between 1.2k to 1.5k, 1/6W carbon.

     

    As for removing the LM6171. I don't recommend for newcomers as one false step could burn the other ICs easily. My bad on the dual voltage, seems like I was greedy back then. Cmoy2 was design for beginners so I wouldn't count on it to be as great (sound) and expensive as other amp. :))

     

    RancidM,

    The default gain would be sufficient as onboard sound gives at least 1Vrms. I would also suggest to get a soundcard if you intend to do serious listening. In my experience, most onboard are noisy.

     

    Heady,

    Thanks for standing in in my absent. Hopefully I will be having some "prototype" next year and let you havefun wif 'em. :P


  4. Thinking of a simplified design that uses 2 x AA. Then it'll use a MAX619 or MAX1642 to step up the voltage to 5Vp-p and it'll be used as the V+ and V- of a single AD8066 chip.

     

    I'm sure it'll be more distorted compared to the cmoy 2 and maybe even the cmoy... but if just might work. Need to get the chips to test out...

     

    Err, someone seems to have done this before. With a 3V opamp.

     

    Was thinking of bypassing the LM6171, c3-7 and setting up the board to use only 1 opa2134 and removing the led to cut a little on power...

     

    Use OPA134 lol, single opamp IC. No need to cut trace.


  5. Sipher,

     

    Thanks but the url isn't complete... here ya go http://www.genesisloudspeakers.com/whitepa...Black_CDsII.pdf

     

    I think u guys should try copying one of the cheap cd presses from indonesia or malaysia. Those are the worst cds i've come across and any decent copy should have a difference.

     

    Long story on why slower burns help. Will point you to an article if i find one.

     

    I have but not conclusive... perhaps my cd player was not resolving enough. Friend did and chose Ricoh as it sounded closest to the original but I couldn't hear difference between Ricoh copies and originals audiophile recordings.

     

    I did hear difference between USA and Germany pressing of a Sheryl Crow album. Contrary to common belief, the german pressing sounded better!

     

    I believe none of us here have (or will be getting) a high end (>$5k) CD Playing source so i guess it matters less.

     

    Up old thread. Interesting read here.

    the word "infamous" here isn't used quite right.

    It gaved me the impression that the H3xx had baaaad sound quality and a rather "cleeean" signal.

     

    I digress.

    H3xx series had never any TRUE line-outs.

    THey are shared with the volume and that is one thing that i hate about it.

     

    *rant* : damn that hiss when i plug in anything!!

     

     

    It may be a true line-out, only that a badly design could make a hiss like that.
