    Iem : Earsonic SM 64 v2
    Cable : Moon Audio Silver Dragon v1 Lod 30 PIN to mini USB

    Very Good clarity , i can hear The cymbals very detail and so Good on my. Theorem
    Mid : very sweet , Clear and clean mid , The midrange from My favorite. Chinese sanger Tong Li so intimate and lush

    Sonudstage : Wide and very Good Depth In My LCD XC
    Hiss : No Hiss on My LCD XC and My Earsonic SM 64 v1 112 Ohm and v2 90 Ohm

    Overall :
    I hear With Medium Gain and turn My volume at 9 o clock , i can hear all the detail and clarity With This set Up so Good
    This set Up is very Good For traveling Only 2 Stags and use IPhone 4 S or IPhone 5 S as my source
    If you like clarity and detail and sweet Clear midrange With very Good bass impact than This set Up is very Good For you

    I thougt the real Copper version was exclusive for the Facebook PROMO - now there are only 2 versions - BLACK & COPPER. The copper version is very glossy and looks like gold. A real eyecather. Sorry EARcatcher :wink:
    If you want to have an Eyecathing portable stack - go for the Copper Edition. And YES, it's a great match with ALL Audeze headphones!

    I have a Theorem 720 connected to a 7th gen iPod 160gb Classic and I am currently running B&W P3 and P5's through it. I find the combination quite stunning. I play these on the low impedance setting and I have no "hiss" issues, just crystal clear sound. All my music is from high resolution sources, recorded on high quality equipment. I am a firm believer in garbage in garbage out. And oh boy if anything in your music chain has been compromised the 720 will definitely let you know it. Don't blame the 720, take a serious look at your gear and how you record it and it's original source. I have a  set of Beyerdynamic T1's for which I am ordering a 1/4 to 1/8 adapter from Moon Audio so I can connect them to the 720 also.
    This definitely is a world class Portable DAC/AMP.

    My Theorem is connected to iphone 4s using Heir 4ai with Toxic cable silver widow. Hiss does not bother me at all.

    I do use Theorem 720 DAC with InEars SD2 with balanced ALO SXC-24 cable. Working great for me....
