I got this headphone for $250 on amazon. I think it is easily worth 2-3 times the price. I like this headphone as much as the Hifiman HE-500 which is $700. The X1 is as beautiful in person as it is in pictures. It has a solid quality feel to it. I’m powering the X1 with the Schiit Magni. I think...

I'm wondering how much better does it get than the HD800. I love my HD800 for jazz which is my main genre of music. So how does the SR-009 do for jazz? Is the SR-009 worth $5000 compared to HD800 for $1500? The SR-009 is a lot of money for a headphone, but I'm willing to pay the price if it...

Thanks to Justin at Headamp for letting me demo the Hifiman HE-500 headphone.   I A/B'ed the two headphones for about 90 minutes. I used an XRCD Ernie Watts, "Classic Moods" jazz cd and a Roku Soundbridge internet radio. I only listened to jazz, which is my main genre I listen to. I should...

For those that have heard both, which one do you prefer and why?   Thanks in advance.

I know an electrostatic headphone requires an electrostatic amp. Does an orthodynamic headphone require a special amp or can you use a regular dynamic headphone amp? I believe you can use a regular dynamic headphone amp, but I just want to confirm.   Thanks in advance.

In general, I like dynamic headphones, but dislike electrostatic heaphones. My question is would I like orthodynamic headphones like the Audeze LCD-2, why or why not?   Thanks in advance.

Is it ok to mix and match different interconnect cable brands and lengths or should you use the same brand and lengths?   Thanks in advance.
