Huh?  Must be a different "Mike."  

 

Quoting my post to this thread, 8 days ago:

 

I'll probably never hear better audio than I enjoyed at the last Dallas meet I attended, when I listened to jazzerdave's proper HD800 rig, with an XMOS-based USB-SPDIF converter, Peachtree DAC, and Cavalli Liquid Glass (with I don't know which tubes), and some balanced copper cables. That HD800 was sublime. I seriously doubt the PM-1 could ever be cajoled into sounding that good.

 

I just don't have the right amp for my HD800.

Does the PM1 sound change much if you close your hands around the grills? If not, these could be turned into great closed cans with some competent modding.

 

For me the sound gets tubey, as in a tube, echo, loss of air and space!

Well he also said many other things, some I entirely disagree with :ph34r: So I'd rather get info from people who I can relate to more, like Frank.

Well, I am not saying I agree either.

Has anyone yet compared them with.....Wharfedale Isodynamics?

 

(Just send your Oppos to me and I'll do it!)

 

Nothing is impossible, but would anyone aside from you or I care?  Come to think of it, both are quite comfortably sitting in my bedside cabinet, so I guess this leaves only you wondering ;)

EDIT - I will add my 2c on the comb effect - there is none, @jerg, the PM-1 are critically damped

The audio quality does not change much when you put your hands over the grills. So there is always the possibility that you can improve the performance, or at least, tune it to a more personal equalization by modifying the dampening material used inside of the PM-1.

Cool, so fully-closed PM1/2 are more than viable through modding.

I've sworn off closed hp's, so I'll stick to the stock grills. :D

This was my un-educated guess on why they sounded more closed than most open headphones...since they appear to leak less and putting my hands on the grills affected the sound less than most. I am curious to see what the more adventurous owners will find inside and the results of modding on their sound.

Yeah...the minor leagues :D

I put the palms of my hands over the grills (not pressing the pads in) and I heard negligible difference in sound.

 

But modding these? :eek:

 

It would be like taking a prime Tia Carrere and tweaking her into a plastic Joan Rivers.

You'd be surprised about the talent of some of modders out there, some even able to make a small business out of it, eh!

After having owned the hd800, i know it's not like every manufacturer out there just gets the "best" out of a product, even if it's their flagship. It's all an affair of compromise and what the desginer is after in terms of voicing. I bet a year from now (maybe even before), there will be pm1/pm2 mods available for sale to those looking for some slightly different voicing and/or other attributes like imaging, isolation and what not.

You could see this as simple economics, where there's a buck to make, someone is bound to get in there. But I trust some modders are fanatic enough to one up the original design smily_headphones1.gif.

No pressure modders wink.gif.

Thanks!

I might have made the PM-1 sound worse than they are in my post. But the best description I found in this thread was that they resemble a better HD650. While they do make some music sound beautiful (vocal range, etc), I am looking more for a jack of all trades.
I'd suggest CIEMs for someone using them that long and at an odd angle. High end sound at virtually no weight and no threat of slipping off. I use my UERMs when I'm at work repairing violins and bows, which is a similar position to yours.
