    JVC HA-FX40 | Believe the hype!

    Thought I would update this thread.  I've had the HA-FX40s now for a few weeks and I have to say, the midrange is starting to get better.  It's still a dark signature but it's very detailed for such a low priced can.  I've been bicycle commuting with these and they sound great.  I can hear...

    JVC HA-FX40 | Believe the hype!

    I thought I would revive this thread since I just got a pair of the HA-FX40s.  About a year ago my Er-6is broke where the foamies attach to the earbud rendering one of the buds unusable.  As I'm going to be having a week long stay in an epilepsy monitoring unit I thought I would pick up a new...

    Low-Jitter USB: Dan Lavry, Michael Goodman, Adaptive, Asynchronous

    Cables, speaker spikes, balanced power, and now jitter.   What nonsense will they think of next?

    Comfortable Clear Headphones for $100 to $150

    Sennheiser HD280s are great for gaming. I would also recommend the Sony MDR7506 (or their cheaper cousin, the V6). The 7506s don't seem to have as good a soundstage as the 280s though, which makes a fairly good difference when gaming. Comfort between these cans is a tough one. The 280s really...

    jumbo sized caps

    It has to do with the time constant of the realistic model of a capacitor. This realistic model of a capacitor is the model of the parasitic complex impedances which are present in electronic devices. The model for a capacitor looks like this: R_ESR is the equivalent series resistance...

    jumbo sized caps

    Typically people remove or replace decoupling capacitors. Also, power supply reservoir capacitors may be increased in value for better ripple rejection.

    jumbo sized caps

    Well it depends on the context of the capacitor too. You can't just go around putting large capacitors everywhere. For example, filter capacitors are precisely tuned, and if you change the value of the cap, you change the filter characteristics.

    EMU 0404 output issue

    Yeah... I'm going to stick it in a test box and check it out, but I was hoping someone would have some good ideas as to where to check. I will base my efforts off of the mod data that is available, as it lays out the analog stage nicely. I figured that since there are a few cases of this...

    EMU 0404 output issue

    I have an EMU 0404 PCI here, and recently one of the channels has stopped working properly. Both channels work fine, but the right channel output level is now much lower than the left channel. I've searched head-fi all over, and done plenty of Googling. I can't find any answers as to what the...
