Considering venting is irreversible, there's no advantage to it at all vs. tape mod, yeah?
Click to expand...


To my ears, there is. The main problem I have is that the taped bowls become hot and sweaty on my ears, so they're less comfortable than untaped L-cushions. Second problem is that the bass sounds more forcibly compressed (to my ears), and venting is more like giving the driiver room to breathe.

I think one problem that occurs with venting is that many people don't want to open the cups just to vent 1 hole, so they vent 3 or 4 or all 10, with disastrous results. My 60i was well-burned in and already had a pretty good bass. Not eardrum shaking, but well-defined. With just two holes, the bass deepened, but retained definition. And I stopped tinkering. I know there are many people who wouldn't stop there, but they would poke more and more holes, destroying the balance between a better defined bass and a low end that dominates the mids and highs.

Meanwhile, my taped L-cushions are gathering dust in a box...

Thank you 020Assassin. I was thinking along that line too.

Would it be possible to create vents/holes without opening/removing the cup? Like using a really small but long screw driver that would fit into the grille, and punch the hiles with the cup upside down (grille side down) to make sure removed material doesn't get trapped inside?

Was actually wondering why the need to open up the cups.

Sure, you could try, but removing the cups is not such a big deal, especially with the 60/80. From what I gathered (I haven't tried it), the build quality of the higher models (more hot glue?) make them more difficult to pry apart.

If you want to open the cups, take care not to blow into the grill or the driver as the hot air might damage the membrane. Just remove the cup from the C-gimbal, put it driver down on the table (allowing the grill to disperse extraneous heat collecting in the cup), and put a hair dryer (fohn) on the table to warm the side of the cup until the glue get warm enough to allow the cups to be pulled apart by hand.

Thanks. Will try that out.

Cheers.

I wonder what amps Grado Labs test the current models now. Still tubes (those you mentioned), or now solid states to keep up with the other preferences of the market. Looks like tge current "e" series are smoothed out and with more bass...looks SS tested to me...?

Graham Slee Ultra Linear Diamond Edition solid state (among others ?)

  I haven't been feeling well these last few days, so my plan to have another take at the PS1000e fell trough, for now, at least.
 
However, I have recieved my C-Moy from Biosciencegeek, 
 
It's the 18V version and has the JRC4556 OP amp, I also ordered 4 more, wich I have yet to try. I had planned to use it in my bedroom with my I-Pod and my SR80e, but next thing I knew, I was listening to my PS1000 and HP1000, trying to keep my jaw from hitting the floor. It's powerful, dead quiet, has great bass extension, and control, and an extended and very detailed treble. As you guys must know by now, I tell it like I see it, even if my findings seam surprising. Now,I am still trying to wrap my head around the fact, that an amp made from an old mint tin, is giving my Grado HPA-2, a run for it's money.
 
Don't worry Parbaked, I still love the HPA-2, and I believe that it performs like it should. I just think that the C-Moy is an over achiever, that's all, so, it's all good.,
 
So, to say that the C-Moy has exeeded my expectations, would be a major understatement.

I reported earlier in this thread that for many recordings, I could not distinguish among my HPA-1, RA-1, and (in my case JDS Bass Boost) C-MOY using my top-end Grados (didn't have the PS1000 at that time yet). 
 
I was using iPod AAC music, as that music was the most familiar to me.
 
When I shifted to lossless (played by FiiO X3), I heard a difference more reliably.  This is one case where I could actually distinguish from iPod quality and higher quality, and not in a side-by-side comparison, but in the ability to distinguish between two amps downstream (C-Moy vs. Grado).  More info here:  http://www.head-fi.org/t/530965/grado-fan-club/20925#post_11123464

I have to say, i like the RA-1 in combination with my "classic" RS-1, but not per se with my PS1000. as i don't have a cmoy, can't tell you much about comparable soundquality between the two...

  Got the T1's tonight!
I just started checking them out right now.

I've been really tempted to get some T1's lately. An odd coincidence, bolstered, I think, by some pretty good prices on it right now!

I posted my impression of then, I don't know if you read them?
If not, in short, they are really nice sounding HP's!

I'm not generally a fan of Beyerdynamics, but the T1 I thought sounded phenomenal. I prefer them to the HD800, and that's saying something! The T1s are typically at the various headfi meets, so I've been lucky enough to listen to them pretty extensively. Just that sticker shock has always kept me away. Really glad to see it slowly coming down.
