    Quick question about the LM317! (and other such regulators)

    i got one in my NAD C300 and it runs hot, damn hot, waaaay too hot to touch, so i thought i could take it off the board and heatsink it on the case, electrically insulated of course, would running 15 inches or so of some wires (nice thick solid core copper) affect it negatively somehow?  ...

    i can't take the noise from my computer anymore!

    i really can't...it has SSDs etc, but it's a gaming PC, and i can't drop the noise completely, i've heard people use those little asus eee thingies, i was thinking i could get one of those (or perhaps a really small pc, as i like to watch 1080 movies), plumb it into an external usb drive, pump...

    Why are amplifiers so different inside?

    i've been eyeballing the insides of hifi stuff since i was a child, anyhow...amplifiers seem so different inside, though they all seem to have a similar 'topology' (layout?).  Do these designs represent different ideologies/end sounds or are they just being different for the sake of it with end...

    Who needs Mains Cables?

    I recently unplugged the IEC from my Cambridge Audio A500 whilst it was still playing.  And it continued to play perfectly for a few seconds O_o  I thought that, considering the amp keeps its juice in some capacitors, how on earth could the mains cable possibly ever alter the sound, as the juice...

    or even better, how to make one am using some wire atm and stereo is hissy unless i hold it in an infeasible manner >_< am thinking i could clamp a TV antenna to my windowsill for good results? i've seen godar ones and they look nice, but are not readily available in England, and are...

    Turning a CD player into a DAC?

    am wondering if i can turn some old CD players i have into standalone dacs, remove everything that isn't needed? I have a 15 year old sony which sounds pretty decent actually, tad too much bass but otherwise great, and looking inside saw this... the DACs seem to be ad712s and have...

    DIY mains power filtering

    hello forum, my last project thing of hooking up headphones to any pwer/integrated amp using a 'flexible box' with swappable resistors is coming along nicely, and i was looking at mains power filters on ebay and they seem rather expensive, and so ripe for DIY! anyone have previous experience...

    HD555 minireview and EBAY information/warning

    sound: great, they seem pretty flat across the board - complements my nad c320bee very well - nothing seems exaggerated, the highs are there and bass can go rather low indeed, bass even exibits texture, not just thump - i guess higher end cans will reveal more in this regard. i really like them...

    I need help with a very simple problem please!

    i am making a box to connect my amps speaker output to my headphones however, there are some issues i can't figure out... here's a horrible schematic of what i think the circuit looks like (sorry for the size) i'm pretty sure a resistor goes at A and B, perhaps a 220ohm? but i'm not...

    using phono plugs/jacks for speakers

    would this be ok? I ask because i'm currently building a little 'box thingy' and it occurs to me that not only are phono jacks very cheap and easy to plug in/out yet very secure, but also, unlike banana plugged speaker leads it's impossible for the connectors to touch each other and 'do bad...

    How can I create masses of jitter?

    i need to hear it, am wondering if there's a way to make it absolutely crazy? then i could make two recordings (of the same audio) of my dacs audio output, one with absolutely tons of jitter in the digital bits and one with just whatever i have right now - no jitter added - and perhaps compare...

    The workings of integrated headphone sockets and converting amplifiers

    hello forum, i am wondering how the average integrated pipes sound to the headphone out socket? I have a nadc320bee integrated and am under the impression it just takes the output from the amplifiers preamp stage, or the poweramps output stage and uses resistors or something to lower the output...
