post #286 of 741

Interesting idea...don't even use a grill at all and just have the stockings suspended.

 

Since we are cutting into metal, do you guys file the sharp edges down so it doesn't scrape the inside of the cup?

I found that cutting the grills a little larger (like 1-2 mm), then filing them down at an angle helps thin them out while reducing the excess.  If you cut them exactly to size, or too small (duh), they're useless.  I learned that lesson with a couple of attempts.  When the edges are thinner, it's easier to get the tabs on the rings into their slots.  Someone told me he thinned the edges by compressing them in a vice.  That was with the Custom Cargrills aluminum, I believe, which is soft enough to do that easily.

guess I need to pick up a metal file now :)

Man, I wonder where we can source the grill material used on SR009s, those look sick.

Doesn't really look like it'll be that much more open than stock grill:

Hard to tell unless someone holds it up against a white background right beside the stock Hifiman grill.

Am I just not being aggressive enough?

 

While I haven't used it specifically for retaining rings, I've used this for prying delicate things before...

Here is my re-grilling with a $1.50 BBQ vegetable grill.  Came out pretty good.  I may file it down some more because the retaining ring sticks out slightly where it isn't clipped in.  Because the mesh is so wide, I was able to fit the retaining ring clips in between.  Very secure and looks really nice too.  Looks better in person.

 

I asked my wife and she said that it looks like it was supposed to come that way!

 

I may put some black nylon stockings as a dust screen.  Although I may not too...I like how it looks without any dust screen.  Plus HFM said in the previous posts that they had one in their factory for years and no issues yet.

 

I'm also thinking of sanding all the black paint off and spray painting it red.  The earlier posts of the red grill looks so great I may make this red too.  I'll post pics if I do.

 

The Grill:

My stencil that I cut out of a piece of cardboard (the centre hole was already there).

 

Finished product!

 

 

PS - The zebra print thing you can see is a custom headband padding that my wife made up for me.  As you can see, it is very wide and has a probably an inch or more of memory foam tucked in the pouch.  A spare piece of cloth is tied lightly on the top to attach it.  Cost next to nothing and makes it very comfortable and spreads the weight out.  Plus, since it is an open pouch, when the memory foam gets flat, I can just replace it.  And no damage/curving of the stock headband.

 

I did the same thing for my Q701's too to cover the bumps.

The airiness, the sound stage...it's just amazing:D

get some tin snips and a file (for thinning the edge).  That's all it takes.

 

Methodology

  1. Use a stock grill to make a cut-out from some stiff cardboard
  2. Use that cut-out and a Sharpie or other marker to trace the circle on the mesh
  3. Snip it so it's just slightly too large (basically, follow the traced circle, but don't go too much inside the marker tracing)
  4. Trim that with the snips and file until it fits
  5. If you can't get the holding ring back in place easily, thin the edge (without reducing the size of the circle; so file straight out from the center)
  6. If you want to attach a dust shield, organza is a nice fabric; could try spray adhesive (use a smaller circle cut-out such that the spray only gets on the outer part of the grill, rather than sticking the fabric to the entire grill surface), or maybe a glue stick.  I tried and can't recommend Super or Krazy glue or kids' glue like Modge Podge or whatever.  They will work, but can be messy.

 

Hope that helps.

 

Oh yeah, and @Nimzerz, get a pair of Q701 pads ;)


How do those memory foam pads sound on the HE-500? I love how they feel, but buying the pads separately seems to be expensive.
Also, which organza should I buy from Ebay/Amazon. Link me up scotty!

The Q701 pads are not memory foam.  They use a stiffer foam, probably to achieve the angle.  While they seem a little stiff at first, after a few minutes they feel like they've conformed to my head.  Maybe that's just me getting used to them, or maybe the foam reacts to contact heat.  I have no clue.  All I know is that they are the best sounding pads (of 5 or 6 different ones I have) on my HE-500s.  The Q701 pads are relatively inexpensive, if you're in the US and order directly from AKG.  You can try their memory foam pads (replacement part for the AKG 702 65th Anniversary model and the K712).  I owned a pair briefly, but only bought them for my Q701s.  Not a good combo for me, but I wish I'd thought to use AKG pads on the HE-500s back then.  Would have been a fun experiment.  The memory foam pads are not angled, and due to the foam used, tend to warm up the sound, so to speak.  They are also almost twice as expensive as the Q701 pads.  If you want to play around with other pads, I'd try the Q701s, and wait for HFM's new pads (the ones that will come with the new HE-560s, and should be sold separately... eventually).

 

re: which organza, I have no idea.  Pick a color you like?  Does one manufacturer's organza differ that much from another's?  Seems unlikely, but like I said...  I went to a fabric store, looked around, held a few bolts up to the light, compared the stock grill with fabric to what looked promising, and settled on organza.  I did try those hex grills with and without the organza dust shield, and actually preferred the sound with the shield.  That's good, cuz my house can get dusty.  YMMV, but these wider grills should open up the soundstage when compared to the stock grills, fabric or not.

 

Good luck!

Oh. Which other pads have you used? Good to know. Yeah, I was thinking about trying HFM's new pads or trying to get someone to make jergpads for me. I just wanna go with whatever has the better sound.

Got it. Thank you sir.

re: pads I've used other than Q701s

Both stock HFM pads, JergulorX pads (;) made them following modulor's guide; 2nd best soundwise), Brainwavz HM5 pads (which were far too bright for me, so I modded them a la the jergpads, and sewed some really comfortable microsuede over them; comfort improved slightly; brightness dimmed a bit), some Sony pads (insanely thick, which cause them to compress a lot, and press pretty hard; soundwise they're not bad, but can't wear them for long).  Shure HPAEC1540 Replacement Alcantara Ear Pads, which have a smallish opening for my ears.  Nice padding, but in the end I find them uncomfortable.  Also, as noted below, the smaller internal space limits the soundstage.  May have to sell them.  I think that's it.

 

Q701 pads will set you back $35 shipped from AKG/Harman.  Pretty sure that's less expensive than having someone make you jergpads.  Two pairs of stock HFM pads are $30 ($20 pleather; $10 velour), plus shipping ($7?).  And no one's doing that mod for free!  It's a fair amount of work, but modulor's guide makes it doable, and he's a great guy who's more than willing to answer questions.

 

I think the Q701 pads rule the roost because 1) they have the biggest openings, 2) they are slightly further from the ears, and 3) they are angled.  The soundstage benefits from all this, and switching to the others seems to compress it.  But my JergulorX pads sound really good.  I inserted the thin dark foam ring that comes with the HFM pleathers (not to be confused with the main foam doughnut ring).  That gives them a little more breathing room, and, at least for me, doesn't compromise the sound.

 

I also do the back vent mod (an optional part of modulor's guide) for almost all of them.  I prefer it.  Some do not, but it's easy to try and reverse, if you don't like it.  One last thing I've toyed with is sealing the pads to the cups using electrical tape.  I think that increases the bass response a bit, and the tape peels off without leaving a residue.  Haven't done it in a while, though, and of course it negates the back vent mod, unless you don't wrap the tape all the way around.

 

In short, these acoustical mods can be tried and combined to affect the sound.  They're all pretty much reversible, except making jergpads.  The majority would argue it's worth sacrificing two pairs of stock HFM pads, but not everyone.

When you say jegulorX pads, do you mean jergpads v2.5? If you think they sound better than those, then maybe I should get some Q pads.

Yeah.  JergulorX is just my joke name for them, since I made them myself.  Some people have said the Q701 pads cut down on the bass too much, while acknowledging the soundstage and comfort factor.  It's all down to personal preference, which means you never know until you try both, preferably comparing side-by-side.  All I can do is offer my opinion.  For me, the increased soundstage and comfort, along with totally taming songs that otherwise have a brutal glare at certain (mid) frequencies, make them the best.  I have no problem with the bass, esp. for some rock songs where I know there should be some deep, rumbling or impact-laden bass.  To me, it's all nicely balanced with the Q701 pads.
