    Hmm, no much info for the Gilmore Lite Mkii Class A, as they only list 1.5W max output without providing W RMS values for different impedance loads like most other manufacturers out there. Depending on the amp's topology, 1.5W max output can be a little light for some current-hungry planars out there. Still, Headamp is known for making great amps.

    Anybody have experience with the THX 789 or 887 and the HE-500? I'm going to buy a balanced amp for these but I want to get the most out of them for the money. Any suggestions are welcome

    The THX 789 is excellent with the HE-500. Balanced output.

    I looked up the fuzzor mod on head fi but the thread is super long and the introductions doesn't really tell me what it exactly does to the sound of the HE-500. Would you mind explaining it a bit to me since I am considering doing it.

    OK, there are a few pics - on that thread or on this thread that should picture it at least.

    I'd use felt with a sticky side, or an open cell foam for absorbing sound in 1/8" or 1/4" depth.

    Let me explain about speakers/rooms for a moment. Recordings assume playback in a moderate sized room with speakers, and some absorbtion, diffraction, and reflection that take a bit of time due to the distances.

    The HE-500 and HE-6 have magnets in front of the front facing mylar. Sound bounces around in there, but at micro dstances, so you get cancellations and reflections - losing some sound, and worse getting very short delays from the initial sound wave and the following reflections. When I first heard it I recognized it very similar to IM distortion.

    Applying foam or felt will greatly cut down reflections in the mids and highs. It's easy to apply and easy to remove. Locate a few recordings that seem too sharp or muddy in the highs and mids, listen to them a few times, take notes, and make the change, and repeat the process. I have heard a few folks say it doesn't matter, most seem to think it does.

    I have a question. Reflections from what? There is nothing between your ear and the membrane. And the magnets are on both sides in the HE-500 and HE-6(SE).
  7. bagwell359
    the backside of the 500 & 6 don't matter (maybe barely) above 500 Hz.

    You ear does not take sound in on all surfaces, in fact the canal is quite a small % off the ear, the rest reflects and absorbs a bit. the rest of your face, glasses frame, hair, etc. the membrare is not attached to the magnet, so sound is bouncing around there multiple times too.

    So essentially it makes the highs and mids clearer and reduces the sharpness of the highs? It doesn't change the FR, does it?
  9. bagwell359
    yes basically. I believe it hasn't been measured.

    I'm at one edge of experience, being fascinated by planar speakers for 50 years, and also room treatments/reinforcement. I'm probably more sensitive than most to this sort of thing, but there are dozens of others who are happy advocates.

    On the he-6 it seems to do more in the treble and not as much in the mids, the 500 gets help in both areas.

    I see. But following the logic the foam should be applied to the ear and everything around the ear canal? I haven't looked up the mod. Maybe that's what it is.

    Well, Jerg says there's absolutely no downsides when done correctly so I might as well give it a try. Gonna have to find some adhesive felt. Any recommendations on brands, etc?
  12. bagwell359
    If you want the best bass seal - use crazy glue to affix the foam to your face.

    Exactly :) What's the point with other mods :)

    I finally installed these pads. Originally the inner fabric covered the four hooks on the rings so I had to do a bit of trimming. Anyway, I much prefer the sound with these on. Before I bought these I listened to a couple tracks with the ear cups pulled away from my ears and things really opened up, with a less 'boxed in' sound, and that's pretty much what I got when I installed the pads. There's no loss of bass either, in fact I think the bass is a little deeper.

    I also just bought a pair of Sennheiser HD6XX headphones. I've heard both good and bad about these headphones over the years so I was curious. They sound ok but they're not nearly as refined as the HE-500's. The soundstage isn't as wide (although not as bad as some state) and the bass is too boomy. But the biggest problem I had was the comfort. I found the clamping force to be too much and because the cups are oval and elongated that they pressed into parts of my face that couldn't handle the pressure, so I could only wear them for 30 minutes. The HE-500's with Ori pads are WAY more comfortable...not what I was expecting.
