Ok, impressions time...
Build and Comfort:
The Isurus is built very well. It's almost funny how much on an improvement the cable is over the MP 8320. It's sturdy, and thick enough without being as unwieldy as the Shure cables. I think it may even be better than the cables on my GR07. It's a very ergonomic fit, and I find them more comfy than the monoprice. Then again, I never really had comfort issues with the 8320.
Sound:
I just want to say off the bat,
get rid of the stock tips. When I first listened to the Isurus, I thought they were a trebly mess. I knew the Nutman said they needed burn-in to sound their best...but damn. I opened my tip drawer and tried out the Meelec M6's double flange tips. Amazing. Bass and mids came forward, and the treble showed some restraint. Make no mistake, they're still a bit on the bright side, but it's nowhere near as bad as it is with the stock tips.
The Isurus is very well detailed and vocals sound fantastic, especially female vocals (justin beiber). I tried some of my favorite songs from various genres, and the Isurus excelled on all of them. As I said, it's a bit treble happy, but it doesn't lack mids and it sure has some good bass. When I listened to "The Way I Am" by Ingrid Michaelson, the Isurus made her voice positively shimmer, and I could hear the drummer in the background slightly rub the skin of the drums. I tested "Papageno" from Mozart's "Magic Flute" opera, and it just sounded fantastic. I then listened to James Morrison's "You Make it Real" and I could hear each individual string being strummed.
The sound stage of the Isurus is just above average in width and depth. It's nothing remarkable really, but still good. It makes the 8320 just sound congested in comparison, both in sound quality and sound stage.
Value:
Ridiculous. Dsnuts has done it again. In a blind test, I would have thought these were worth 5 times their price. Whether or not they're really CKM99 rebrands, they sound darn good. I wish I could give you a big man-bear hug for your work, but I guess thanks will have to do.
Remember! Try different tips!
