Im in kirkland  WA and would like to participate in the tour. I agree to follow the terms of the tour.

is anyone bringing an AT r70x?  or an elear?  or a stax ?

anyone know how to release the front section with driver so as to gain access to behind the driver? it seems the white section stays with the black outer plastic section and it comes off as one? how is that pair released ? apparently they simply pull straight out? seems quite secure in my case...

hello good sir !,yes they are turned inside out ! good eye. then some spandex stitched to the back to serve as an attachment mechanism to the cups leading rim.....I think they are akg 240's? or some other replacement pad. They where under $10 and are just about the right size imo.   the Foam...

    This is what i've got at this point. Angled driver, diy pads, and a 'central foam column ' mod. I'd recommend trying this should your particular set be dominant in that area.             

too busy, but chose 4 sets and hope to mess with them soon.....

just to chime in here with some updated sound reports f​rom the f​rontlines.....I've heard 3 sets of​ the drivers and am enjoying them. I still need to diy f​abricate some proper pads and so f​inal impressions can only come at that point. What i've noticed is quite a nice degree of​ consistency...

here's what I've got as far as grub screws (put 4 in for each cup but probably only need/use one, to just put pressure on the driver edge and driver the entire driver tight to the remaining sides of the cup). I will probably still try and size the overall lip opening to be a press fit although...

    the naming of each corresponds from left to right in the pics       Spent a couple hours searching ebay for some suitable pads for the standard grado style cup, as an alternative to the typical foam. All these need to be modded particularly on the back to decrease the attachment...

@fleasbaby You should be able to get the allen set screws to work fine even on the angled lip of your last cup. Just use a drill press with the cup clamped in proper position to drill the guide hole. Or a super steady hand drill as long as you remain square with the driver edge and disregard the...

@speedking....great namesake by the way!! deep purple fan? In any case, you are lucky to have a set of H's come your way. Let us know what you think of them in comparison to the ypsi's. I have not heard the H's but have played with the nak7 driver which is the same as what joe used. He had the...

 general categories of modding opportunity:     1) the driver to cup 'coupling' and the size and density of the front section. Basically one has the choice of sticking with the stock RS style grado cups where the pad hangs on by that little rabbet/recess and the front section is more/less the...

I've got some of that adhesive backed bandage tape. Good idea to use it for the driver covers. it might affect the treble however. at least the variety I've got in front of me....I was using it applied to the back of driver -outer ring of vent holes....had some good affect there.   jav's cups...

world class pepku. Nice! How's the sound?

got a chance to hear these drivers. Nice balance of resolution and presence, not too smooth and not too hot. Plenty of depth and detail, neutral without being sterile. Nice overall EQ and bass to mid transition. Plenty of snap and dynamics without being harsh and too grado'y.

@fleas,Thanks for the link, I wonder why the google search didn't turn up a link to their page....

nice review fleas.....If they want to move some of these units a link to their site would help, as a google 'Elleven Acoustica Ypsilon' didn't bring anything up for me? ......hey sling how's it going!? Sounds like we got a new driver to play with! .....time to get busy fine tuning this beast eh...

how is the midrange and vocal presentation compared to a magnum and pink driver? is it distant like a senn or up front like most grado drivers?   how is the presence/resolution balance? meaning is the upper mid 'hot' at all like grados or is it super smooth and resolved like the senn and some...

yes, that aluminum does retain the cold like no other material. You guys may need to source some kind of sticky cheeslothe type material to laminate over the driver face......when you guys give impressions of the new drivers it would be helpful if you mentioned some of the albums you are using...

is that wrap of the driver a substantial aluminum or is the driver still about the same weight as the magnum/grado? 

a more resolved RS1 is surely right up my alley. To increase resolution without losing that RS snap-dynamics is the target for me......as you guys make cups for the driver, and if your favorite grado style pnone is the RS series,  keep i mind what made the grado RS 1 so great. That natural...

what!@#%%%?? a mature natural reference sounding grado design? A creature like this should not even be discussed on the headfi site but......it is intriguing. Extended bass, sans mid bass hump, smooth but detailed top end? sounds about right to me. I need to find the site to order a pair just...

@FLEAS....you sure do like your hot glue! It does have many uses and this one is probably fine too as it does serve its purpose in that it sets up semi soft......If you can ever try the same set of drivers in this cup compared to another of same wood, and with the same driver mounting method...

@fleas         the material is 3/32" foamrubber (on left).....the other is 1/8" harder rubber. Either or any similar could be used at this point since we don't know it's affects but the theory is that we just want to introduce something in there to break the cup up.....whatever you have...
