Audio Zenith PM-X
« on: December 08, 2014, 09:16:26 PM »
Someone sent these to me. Similar in spirit to the T50RP mods, but this one is based on the PM-1/2. I'm not sure what the headphone is called, but I will refer to it as PM-X for now.

I've given them a brief listen, and I must say they are really good. I'll run them in through its paces when I get more time. PM-1 was too laid back and close. PM-2 with the PM-1 alt pads was just about right with just almost discernible slight treble peak. PM-X is almost another headphone. It maintains the PM-1's deep bass while being very open sounding with lots of air and very smooth treble. It also has more bite and is not as laid back. Actually tuned a lot like the Paradox.

Measurements forthcoming. Shitty pix attached.

Measurements attached. BTW, I have absolutely no idea what was done. Pads are different, but I suspect driver mods as well.

Much smoother FR in terms of transitions to PM-2. No dip at 5kHz for PM-X. Smooth transition from upper mids to treble. The smoothness can definitely be heard. Compare to PM-2: http://www.changstar.com/index.php/topic,1720.msg45757.html#msg45757

What is the pad material? Looks like the original velour, but much deeper.

No idea. I'll let the maker volunteer that info. Pads do seem deeper than the original. Fluffy with solid support.

Nice FR. I imagine the distortion would still bother me for the things I like looking for.

I'd probably unjustify 'AUDIO' in the logo but that's just me.

Very nice measurements. Is resolution impacted as well?

Distortion looks to be taking a roller coaster ride after those mods...

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin

I thought the same at first, but it looks more or less on par with stock when you try to flip back and forth between them
