Symphones Magnum upgrade for Grado SR325 and Alessandro MS2 - Page 156

post #2326 of 2335

the other big factor is the metal vs wood cups. the magnum you have is in metal and so you are hearing very little to no 'grado presence'. Part of this I believe is the magnum designer deliberatly dialed it out of it's driver but I also feel strongly that metal cups inherently offer less of this grado presence. Which is evident in the 325 model. This is the most solid sounding, highest 'resolution' model grado of the sr line. The hf2/ps/ etc also share this quality even to a higher degree because those drivers seem to be more resolved as well. So you have a resolved cup with a resolved driver........so the point is that the RS wood cup model to really sound balanced in this way would be designed in such a way as to minimize the grado presence and should be fitted with a low persence driver because the wood cup is inherently more 'present' sounding than metal.......interestingly -to me- i've found similarly that iem's as a general rule, are almost exclusively have the more resolved sound. I haven't found one that has very much if any grado presence or any presence at all really. This tells me that grado presence is a result of either reflections as the sound is bouncing around as it enters the ear (since iem's don't need to navigate the outer ear) OR more likely, that grado presence is at least parlty the driver/cup interaction. The other part is the driver itself. We can hear that magnum drivers themselves are more 'resolved' as a general rule, and so that is proof some if not all of that extra presence is the driver. The dilemna for me is the dynamics of the RS style cup. To marry those dynamics with the resolved driver sound is the ideal grado that has yet to be built imo. although many models come real close including a good RS, HF2 or magnum example.........But this is all pretty nitty gritty stuff, in the end it's good enough to get close, use a little judicious e/q and call it good enough......that still leaves you with the same decision however, whether or not to revisit the rs phone. So I haven't helped in that regard I guess. I'm offering some grado musings for the hardcore fans among us I guess.......

It's partly the reason I returned to the RS1 for the wood resonance.  I felt the wood and the RS1 depth was responsible for the sound.

Knowing the Magnums were superior yet lacked that "special resonance", I chose the RS1.  I always choose headphones for the "musicality, tonality and timbre" over transparency and accuracy.  But that's just me.

so it sounds like you've already traded the mags for rs1.....enjoy!

Step 1) Buy RS1

Step 2) Sell whichever headphone you find yourself picking up less, or keep both.

Rhydon wanted to make a better Alessandro MS2i, that is, a more neutral and resolving John Grado-style driver... the headphone came after in the form of machined aluminum alloy part replacements for their stock ABS plastic counterpart, inspired by the Joseph Grado HP 1000 (the ideas behind it, I would guess).

 

That's pretty much what he achieved; though consistency in sound signature at v4 is fairly bad according to thelostMIDrange (and chrislangley4253 too?). Prior to the v4 and v5 (Turbulent X), there were also in this thread the v1, v2, v2.5, v3, v3.5 and gray v4. If I remember correctly (the beginning of this thread) only the v1 were a direct upgrade of the stock SR325is/MS2i drivers via de-stressing (de-coating?) and doping.

 

The drivers are a lot more closely matched (like 0.01 dB vs. 0.05 dB for Grado) thanks to an exclusive technique he has, and because of their smooth highs they should be a tad less fatiguing to listen to. Wearing comfort is something else altogether that one needs to learn how to deal with for every Grado, even for the lightest wooden models.

 

PS500 drivers have three holes punched in their back (like the GS- and PS-1000), you should expect an increase in bass (and normally, consequently in distortion, too). I have no idea if the HF-2 also does that. The RS-1 doesn't.

Anyone know how to get ahold of Rhydon?  His old email address (rhydon@symphones.ca) isn't working.

I found another address: info@symphones.ca  I sent an e-mail to that address today a bit earlier.  I didn't get a bounce back, so I guess it still might be active, but not being monitored?  Does Jin of Turbulent Labs have any connection with Rhydon?  He might serve as a good conduit to get through to Rhydon.

Rhydon stopped making Magnum's based on my last exchange with him (almost two years ago).

But it really is not that hard to source the parts and build yourself (you just need Mark to match your cups and drivers. He loves doing it:)

Sorry for digging up an old thread, but i was just wondering if someone could spare me reading 156 pages :)

 

I have a brand new Alessandro MS1 and just discovered the Turbulent Labs page, very attractive :)

 

How do these cups change the sonics in the MS1, and did someone listen to their driver (Turbulent X Driver)? How far is it from the original Grado Sound? Does it add some Soundstage? 

 

Thanks a lot
