    Fiio A3 vs ?

    Looking for an amp ~$100. What else out there would be better the A3 ? I will most likely be using with basic 32phm headphones like apple earpods and koss/senn. What about the Sabaj PHA2 ? I like the chip in it but its not clear how good the amp is. There's not much talk about it here. Also, I...

    Fiio E17 or V-DAC II ?

    Ok I have narrowed it down to these two DACs for use in my home stereo system. This dac will be see very little headphone duty. Its mainly for spdif input and line output. The V-DAC II is twice the price of the E17 and people everywhere are raving about both these dacs but what I am trying to...

    If I didn't like SR60, DT235 will I like SRH440 or MDR-V6 ?

    I did not like the Grado SR60 and Beyerdynamic DT235 because of their treble response. I found that to be too bright and harsh to my ears. However, I have always and still enjoy my KSC-75. Also liked my AKG K501. I am now considering the Koss DJ100 and its #1 on my list, but also wanted to...

    Recabling Koss KSC-75 worth it ?

    I have already done the drill-holes-in-the-grill mod. I was thinking about recabling it but upon examing the cable it doesn't look that bad. Its ok. So I was wondering if it will really make much of a difference upgrading the cable ? Can anyone share their experiences about that ? Again, this is...

    Audigy 2 NX - 44.1 Passthru works! but is it bitperfect ?

    So I did a spdif loopback test (rmaa) on my Audigy 2 NX and confirmed that the 44.1Khz passthrough works fine. But I am not quite sure if its bitperfect or not. Here's the thing - If it is really bitperfect then when I set the Volume, WAV and Input level sliders to "max" and I play a -6db...

Well here it is - the full range distortion measurements for the headphones I own - KSC-75, AKG-K501 and ipod nano. As a bonus it includes the...

    Using KSC-35/KSC-75 drivers in another 'headphone'

    Has anyone tried substituting the KSC-35/75 drivers in another headphone ? I have been tossing around the idea of putting these drivers in a over-the-head type headphone but have yet to find a suitable "enclosure" for them. Any ideas ? suggestions ? This will also allow recabling the ksc-75...

    So what's the latest on USB Asynchronous and Firewire ?

    Haven't been in touch with this subject for a long time so I thought I'd check if there have been any updates. Last time I checked these weren't viable (or available) options for goodquality PC->DAC interfaces. USB Asynchronous was running to OS issues. And Firewire was unclaimed territory (boy...

    AKG K501 Impedance and Acoustic measurements (pics inside)

    So I got a K501 (and a HD595 to decide which I want to keep). After some listening impressions I thought about doing some tests. Blue is the response. Yellow is phase. Impedance: Now comes the fun part. I share the common feeling that this headphone is lacking in bass. Keep in...

    Ready-made headphone (re)cable

    Hi, I have recabled a headphone in the past from scratch (teflon silver wire, techflex, canare plugs,..). This time I am looking for ready-made cable that I could use to recable my KOSS KSC-75. The reason I want to go that route is to preserve as much portability and flexibility as I can of...

    Which current model PDPs can I use with an external USB DAC ?

    I realize that almost all current PDPs have a USB connection. Does that mean I can use ANY pdp that has USB with an external USB DAC ? or the pdp's usb needs to support digital audio transfer ? In that case which pdps do support that and which do not ? Thanks.

    USB or SPDIF/Optical digital link ?

    What are the basic/main differences - besides the speed or bandwidth ? Technically, is one better than the other from a 'digital audio interface' point of view ? Thanks.

    Why not just use a buffer instead of an amp ?

    I am trying to understand the buffer concept in headphone amps. From what I understand so far, a buffer has high input impedance and low output impedance so it will load the source 'lightly' and can handle high loads a its output i.e. is able to provide more current to its load. Now...
