Final Setup goes like this:
Dell Studio XPS 435MT → iTunes ALAC → USB → NuForce uDac → Little Dot I+ → Headphone
Songs: Colbie Caillat I won't, Coldplay Clocks, Diana Krall Broadway, All Night Long, Diane Schuur Caught a Touch of your love, and Bach's Cello suite No.1 (from YouTube unfortunately).
HD600 (OCC Cable): Detailed, smoother than previously heard. Very enjoyable and fuller sound. It seems they now have the power to perform as they should. These sound fantastic for Jazz, and Diana Kralls voice sounds fantastic. The bass guitars, cymbals, piano... all very inviting and smooth. I really like how these perform.
K702 (OCC Cable): Played Bach first, and I can immediately hear and feel the larger soundstage. Where the HD600 gave me nice full music... the K702 gave me the detail. The HD600 sounded like I was in a Jazz club, the K702... as if I was at the Phil Harmonic. Different presentations, but both very enjoyable. Great presentation in general.
K702 (SWZ Gaming Cable): Smooth sound. Good punch to the bass. Less detail compared to the OCC Cable. With a tube amp, OCC Cable. With a Solid State Amp, the SWZ Cable sounds better to me.
SWZ SR-80i (modded): Wow, Go GRADOS! This is what I was talking about! First song I tried was Bach's Cello... and the Grados sounded FANTASTIC! BIG Soundstage, Clean, pronounced and IN YOUR FACE sound! They must have perfect synergy with the OFC Cable, W.E. 408A tubes and the LT1364 OpAmp. These took the cake for Bach! Colbie Caillat sounded great too. Her voice carried through nice and clear. Coldplay was nicely delivered. Diana Krall's Broadway sound was great. The stand up bass guitar plucks were tight and felt. Piano and cymbals were quite crisp. I love these headphones! There is a portion in the song where the drummer is sliding a brush across the snare drums. This is almost lost in the HD600, you can hear it on the K702 with the OCC cable (not so much with the SWZ cable). The Grados do it the best justice though.
So, now... after listening to all these headphones in their different configurations. Listening to the different genres, it's easy to see they all have their own strengths and weaknesses. I really enjoyed them all. I definitely enjoyed the AKG K702 much more than I thought I would. They were EXCELLENT for gaming! So, your wondering. Which one would I put my hard earned money on? Well, very hard question. I have realized, that I'm a Grado guy through and through. So, I'm going to be looking into going up the Grado ladder instead of going towards either the K702 or the HD600 for music. Not knocking those two headphones because they are phenomenal! The synergy the Grados have with my Amp can't be denied. They sound utterly amazing! So, it's time to either save up for a higher end Grado, or for a better Amp to do the other headphones proper justice in the future. I want to thank PJ for allowing me this opportunity. You have some AWESOME headphones there buddy!
