Hey guys,
I've owned my amps for about 3 years now and they have started to bug out. I will get the left and right ears losing volume and ill have to push in their cables to get them both firing at the right volume.
 
I hit up Sennheiser and they recommended a new cable set for $137 plus shipping..

Any advice? sounds like a few other people are using different / better cables?

you can buy hd25 cable for them on ebay etc, if you dont need a remote on it. the cable might have broken at the point it comes out from the band, i had it new and it was already chewed on cause of they way they are designed.

Are you talking about damping? That's one thing that was improve from the HD25.

I really don't hear any resonance issues with the Amperiors...

There's some ringing. So to be fair, I suppose the decay of the mid treble is pretty damn fast compared to other headphones, though I mean it still sounds boxed in, you can hear the treble bounce off the casing a little bit as it sounds a bit "metallic".
 
@Slaphead Very interesting stuff, though I would think everyone be trying to find the most ruler flat headphones for all these functions, and with slightly emphasized bass when mastering, because most people's audio equipment emphasizes the bass. I know when using speakers, there's apparently a certain speaker everyone uses as a golden standard because it mimics consumer audio equipment.

I guess it's there but I just can't hear it well. But thankfully, it isn't as apparent as, let's say, the Beyerdyamic T1, which is worse considering it's an open-back design.

Can somebody write up a brief comparison between the amperior and the aluminium.
Is it true the sound is more forwards and aggressvie with the lower impedance driver of the amperior?

I changed both earpads to the Amperior Velour ( I had spares ) and compared side by side. They sound identical. The only difference was the position of the volume knob on my amps when doing volume matching. The aluminum needed more degrees in the turn than the Amperior. I'd take the Amperior due to it being slightly easier to drive for portable use.

but surely there has to be some differences due to the different impedance drivers used.  
I don't know if I should just save money a used hd25 for $100-$150 or a brand new aluminum for $299 with 2 year local warranty. I've heard the the aluminum cuts themselves is worth the asking price because it's made of a single block which is expensive. I've owned 3 pairs of the standard hd25 and one amperior and if this aluminum edtion is going to the last iteration of the hd25 then I might as well spend the extra money as a memento of these legendary headphones.

Interesting! Thanks.

Is it just me or is the hd25 clamping force supose to be high than the amp & alu? 
Could it be that I'm finding the alu to be lower due to the more cushiony pleather pad as oppose to papery textured pad?

Along with the plushier headband pad of the Aluminium, most likely yes.

Any suggestions of where to buy the Amperior refurbished or used? Or...how do I find out I f a fellow headfi'er is selling a pair? Thx for any help.

in the sale/for trade forum here. I would recommend you getting the aluminium though.

Has anyone swapped higher impedance hd-25 II DRIVERS into amperior cups? Would the be an improvement?

that would be a good experiment! 
 
wonder if that would close to the hd 25 aluminums (though the earpads are different) compared to the amperiors.

Why is that? Are/they that much better than the amps? (I think the amps are great)
