I'm really considering pulling the trigger on a pair of Cabillas' cups, but I'm hesitant to do the soldering myself.  I'm going to look into the process a bit more and see if I can become comfortable with it, but if I decide that I don't trust myself with it would anyone be willing to do the soldering for me?  It would not go unpaid.


I'd take on the work.  I have all the right tools for soldering.  Meanwhile, my 2nd set of Cabillas' cups are waiting for me at the post office.  Though, someone else's SR-225i Grados will be going into them. :)

Hey, Hey.  It was me who had an idea a few weeks back of making a mold to use a combination of MDF dust and some agent to hold it all together.  Since MDF works so well for subwoofers, I was assuming that it would also do well for the bass on headphone cups.

Thanks.  I feel a bit more confident now and I think I'll try my hand at it first, but I know you're a trustworthy guy and I'll keep the offer in mind.

Only problem is...on Cabillas cups, where do we brand? If we brand the sloped sides, it'll be way harder to create a circular brand that's angled, right?

Also, TWO sets of Cabillas cups? YOU LUCKY DOG, YOU!

And what do you mean "someone else's" 225i's?

Oh, someone asked for some "assistance" in getting a pair of SR-225i Grados with Sapele cups up and running.
 
I think the cup molding process would be kind of neat if we had the right materials.  Of course, we'd have to get into some faux painting of them, though.  Maybe, a marble-styled cup?  Would that speak classy or what?

I've been listening to this set non-stop for the past couple of days. Completely in love with it. They have that unmistakable Grado sparkle, but all of the frequencies really come together. When these are on my head, its so easy to forget about analyzing the sound, and actually just enjoy the music.
 
These started off as SR60i's and now have Cabillas sapelle cups, 8-conductor 28AWG wire, 4-hole vent and a small thin dab of dynamat on the back of the drivers. 
 
The first mod I threw on were the wooden cups, and in my opinion this was the most subtle. It's not a night and day difference that blows you away when first put on. You don't get more detail that pops out at you. You don't get a huge jump in bass. But what the wood does do is color the entire spectrum. The high frequencies really smoothed out while still maintaining the details. The presentation warms up, making it more mid-centric and giving it more body. The timbre of instruments truly sound more lifelike. It's as if you take all the sounds and filter it through the color/resonance of the wood -- it's more cohesive. One of my complaints about the SR60i is that the midrange is really congested, and instrument separation isn't fabulous. I didn't hear any improvement in those aspects with the wood, but the sweeter presentation makes it much easier to overlook it.
 
The silver wire was the second addition, and I had a "wow" moment as I immediately notice a jump in detail retrieval. The upper frequencies were littered with all sorts of detail and stimulus for my ears to sink into. It seems that little elements jumped out on songs that I never even really noticed with my K701s. Bass gained some definition and texture. And the imaging improved, with better positional cues making the soundstage sound a bit more open, a good degree deeper, and more three-dimensional. 
 
The last mod I did was venting the drivers. I was really surprised at how big of a difference this made. I only expected the bass to have more punch, which it did. What surprised me was that the midrange gained a ton of clarity. The congestion that I found disappointing with these were not an issue anymore. I'm not sure if it was just venting the drivers by itself, or if it just synergistically clicked with the other mods, but everything truly fell into place. When the drums kick in on Fleet Foxes's "Helplessness Blues", the bass is so dramatic and authoritative. The drivers still don't reach the same levels of sub-bass as my Pro900s, but they will provide a satisfying thump on most songs nonetheless. 
 
One thing that is disappointing, and I suspect it is the fault of the silver cable, is that it has become so damn unforgiving for poorly encoded or poorly recorded songs. I use this primarily with my 160GB iPod, filled with mp3s that I've amassed over a decade. Many of these songs are encoded at 128 or 192, and these headphones are relentless with them. I get so much grain and static at the upper frequencies that half of these old songs are unbearable to listen to. This was not a problem for my Pro900s or K701s, which are a both a bit notorious for being unkind to poor sources. There is no problem when hooked up to my desktop rig pumping out FLAC files, so I suppose I'd better start upgrading my source files. These cans are certainly worth the trouble.

Soundstage wise? I've been wondering if the drivers make any difference to the soundstage or just the housing..
 
 


I don't notice any difference.

Chris,  A few comments:
 
  1. If we could get our hands on the drivers that are used in the MS-Pros, imagine the possibilities?  I realized Grado doesn't sell parts, but I've never tried asking Alessandro if they would.  It was Alessandro after all that sent me a replacement MS-1i driver after all.  Hmm ... I wonder how many parts they stock and if this might be an option?  I've just fired off an e-mail to see if this is an option.
 
  1. I'm sort of with you on the "tape on the pads" issue.  I do think that one gains a bit of bass (small percentage), but I do feel that it does take away from the comfort.  Also, I think that the tape prevents the pads from "breathing" by blocking air that would get through the foam and make  your listening sessions comfortable.  I know with other bowls, pads, etc. from other manufacturers, I don't feel as comfortable wearing them - with the exception of my Sennheisers, with the soft cups that surround your ears.
 
  1. The sound (in general).  I'm quite sure if we all tossed our modified Grados / Alessandros in a pile and then listened to the others and tested them out, most would be within a 5% variance of each other, but probably not much more.  However, that is what keeps bringing up the question - how much more are you willing to spend to reach for that last 5%?
     
 

that would be amazing. i'd be willing to put down 100 for a pair of ms pro drivers. maybe even more.

 I never punch any drivers, because i think that grado have enought bass, dont you think?, or what can i get?



I do think they have enough bass, I don't mind one or two holes poked. any more than that and I think it is too much for quite a few recordings.


Quote:
im happy with 6 holes too 
biggrin.gif

4 was just not enough for me.. i put 6 holes then placed some blu tack and thought it sounded awful (maybe i used too much) so i removed some and left a really thin layer of blu tack ..listened to it again and it made a big smile on my face
beyersmile.png

i wonder what will happen with 10 holes..hmmmm..



1-2 is what makes me happy ;) to each their own.

I had kind of the opposite take on the cups and cable. I got a wow effect from the cups.. and I didn't feel like there was too much of a change with the cable, but i did have a source upgrade at the same time. silver definitely made a difference on my portapros so i'm sure it didn't hurt the grados at all :)

So I practiced soldering today...not so bad. But I don't have clamps, so I found fidgeting around with the iron and the vacuum to be a pain because the circuit board would move around...anyone know a good makeshift clamp setup for soldering my drivers in?

Chris, Sadly, Alessandro responded to my request yesterday.  They indicated that the MS-Pro headphones can only be serviced in-house at their location.  They won't sell the drivers separately.

How about laying the object you're trying to solder down on a rubber mat.  That should keep it from moving around on you.

Friend, I believe we misunderstand each other. I think you're talking about molding the entire cup, while what Kojak and I are getting at is making a brand of sorts to stamp the "GRADO PRESTIGE SERIES" on the cups.. (: If I understood him correctly.
 
@Kojaku: That's one thing I've noticed about 'most all the cups that have appeared here so far, it seems like everyone has cups which slope inwards (the recent MartyRS1-clones?) or slope outwards (Cabillas), with none actually imitating the Grado flat-topped style. I've requested cups in exact imitation of the HF2s (shape-wise) from Bila and he got back to me with pictures which fit pretty closely a (rather long) while ago, if this whole thing pans out nicely we shall see what happens (:

I have this to hold cables and stuff while solder. very cheap and useful http://www.amazon.com/gp/product/B0002BBZ2Y

Harbor Freight sells one of those, they put it on sale a lot for like $2. I have 3 or 4, they have come in handy many times for thing even other than soldering. I can't imagine soldering without it.

Ok, first impressions about Martin Custom Audio MS1.
 
No pics. There's a catchy start
redface.gif

 
However, I'll just state that Marty did excepcional craftsmanship work. Flawless (almost).
 
So you get your wood box. From the pic my wife sent yesterday it looked like pine. It's not pine, and I cannot really tell you what it is in English since the word is missing on my vocabulary at the moment. We have here some prawn boxes sold with that kind of material. It's nothing fancy, but it's well built, with some nice details on the interior to accomodate de cans and really stands out among this mod business with attention to detail. Pics to come later.
 
The headband is perfect. I've read a few coments about how unconfortable the lower end Grados/Alessandros feel on the head. I know what they are talking about as my previous experiences proved it beyond about an hour of use. They hurt. Not Martin's. The leather is really soft and has a lined padding on the underside that not only looks the biz but works on a top level. Great marriage between form and function.
 
The cups and gimbals are amazing. Very well crafted, sanded and laquered. Padauk on the gimbals and Cebil wood on the cups. On their own both woods look exquisite. As a matched combo it's like a piece of art. My crappy camera will never capture that beauty accordingly. I'm also a poor photographer, so just believe what I'm saying. Pads are bowls. I need to work out a leather pair later on.
 
Remember the almost flawless remark?
The almost comes out because of the rods.  The actual rods are made of brass and they attach to Cebil blocks. Great idea to slide the brass through the wood to adjust hight. Looks wonderful. Works wrong. The wood quickly erodes with the friction and the cups come off if you lay the cans on the table top. I need to fix this.
 
These cans have been recabled with 4 strand silver cable. A 5 footish piece and another 5 footish extension cable. Works out just great if I take these on a trip as I don't need a long wire to connect an iPod or iPad.
 
As for the sound, I had a couple of hours listen. They did a few great things and a few really bad things. I need to adjust my brain and tune in. I was also anxsious to come home and grab them after this looooooong wait to finally resolve all the pending issues with my initial order. I'll post about the sound later on as I feel the need to relax with them e let myself go. No love at first listen though.

Had a decent listen today. My ears hurt a bit for being forced against the drivers. The bowl effect maybe? Like I said previously, I need to try some more options. TTVJ's website seems to be down... those flats should be interesting if he ships to EU. 
 
Anyway, I promised some pics. I warned against what would come out of it so... here they are in the wooden box (forgot to take pics of the extension cable but it's irrelevant)
 

 
The box is quite well built and the foam coating gives them a nice cushion. I'll use the box to storage them as I have quite a lot of stuff spread around the listening area.
 
Because of the recable, the drivers are now glues against the cups. I won't be needing to open them up. 6 holes opened and the drivers are really close! I like it forward sounding and detail is also important for me.

 
It's hard to tell how much worse this could of come out with the flash... but the headband is really smooth and comfy.

 
A side overview of the cups. They're not really that red or dark brown. They look really nice and classy.

 
A bit more detail over the problematic rod. I'm yet to fix it as I just wanted to listen to some music...

 
A more realistic view of the cans true colors. My Basset Hound Luna decided to inspect the Neutrik plug and cable. She's a bit shy :)

 
Upon further listening sessions my brain is beginning to adapt to them. Today everything sounded much better, although some of the problems I noticed yesterday are still there. They are beginning to grow on me!
 
Sound Impressions
I've been listening almost exclusively to these cans this last few days and I'm ready to share some info.
 
These don't sound much like the Grados I've listened in the past. Actually, these are MS1s... With 6 holes vented, the bass is oustanding, quantity and quality wise. The Grado signature I recall wasn't exeptional like this. The mids are quite well integrated despite the upper mid hump. Highs are clear, but recessed. The overall sound presentation is very engaging with the right musical diet: acoustic and electric instruments. as well the kick drum and tom-toms. Piano is listenable. Horns are delicious, but not realistic. I have also found a few issues with male voices.
 
I started out with Paco de Lucia's "Solo quiero caminar", an excelent rendition of Flamenco and Fusion tracks where the acoustic guitar is king (besides the player). The recording is very well made so it will sound great on any system. With these cans the guitar comes alive with the singing and clapping well placed on the background. The sound is crisp, the body of the guitar breathes air into the cans and there are loads of air between the strings.
Against the HD600, these present more upper frequency energy and air. The timbre sounds more correct. There's little string snap and the presentation is not as forward. There's soundstage.
Against the Lambdas, the conclusions are pretty similar as reported to HD600, with the difference that you also get the string snaping but a more forward presentation.
Against the modded HFI780, the Ultrasones cannot provide the same level of detail and agility. They do snap like any other and the presentation is the most spectacular as far as prat goes since you have your face inside the guitar body.
The MS2s are front row. The HD600 is middle of the room and the Stax sit you row in between. HFI780 wizips you inside the main focus instrument.
In the end I loved the Lambdas and MS2. Not really an absolute fave here.
 
The next rendition went with Pavarotti's "Nessun Dorma" from the MSFL recording of the Carreras, Domingo and Pavarotti pop-aria CD. The MS2 fail miserably ruining Pavaroti's performance. A few good systems have made me cry a few (manly) tears; however the MS2 simply cannot handle the old man's diaphragm pushing the tone higher - it's strident and unpleasent. I repeated the dose yesterday and, without EQing, the same result came out: a disaster. With EQ it is ameliorated, but not first rate.
All comparo cans provide a quality rendering of the event except the MS2. The Lambdas rule supreme.
 
Next up we have Porcupine Tree's "Metanoia" record. One of my PT faves and have listened to it inumerous times.
The MS2s begin to show, again, what they can do. This recording is extremely atmosferic and provides amazing dynamic range. It's very easy to slide down the couch for the entire recording. The MS2s provide an astral experience here. Drums recording and performance are world class and these woodies know what to do. Fleshed out skin interwined with the guitar and bass... playing together... wow. It's not as 3D and layered as the Lambdas cand do, but the Stax just sound right to down good. The MS2 are almost perfect. The HFI780 onde again are very fun to listen to, but there's too much detail left out. The HD600 do a great presentation again; they sound right but don't stand out much. The MS2 are hindered from the alluded recessed top end - much of the airyness is left out - HD600 are king here, and the Lambdas... also. MS2 cannot do macrodynamics as good as the microdynamics - they sound a bit "short" in this regard, but this is a pure relativisation to other cans because they really sound f~"#%%g great.
 
Keith Jarret, La Scala's on ECM. Another emotinal trip record. The HFI780 cannot do piano right - it´s a percussion instrument but instead of a pair of hands doing the work it souds more lika a pair of hammers... let's move on, nothing to see here. HD600 always did this recording in a most remarkable way. Not because of the piano in itselft, but because of what's around it. It draws the concert hall in depth and hight. Not much height, think of a rectangle instead of a square. Lambdas do the square, a big square, but the forwardish nature introduces a few trick questions about the concept of rightness about a grand piano in a big room. Both are exhilarating though, and yes, if in the a certain mood, I can spill a few (manly) tears listening to them. The crispness of the MS2s and microdynamics they portray make them a great pair of cans for solo piano. Left hand side there's great authority, warmth and body on one side, on the right hand side there's also loads of crispness and agility. Keith's "singing" comes out perfect. I'm undecided on the fave can: HD600 or MS2. They sound way different!
 
More to follow. I know, what about "Rock" music, man?!
