Sennheiser 650 Headphone Cable Upgrade

I'm a longtime fan of the HD650 for its coherent, non-fatiguing sound, and great value for the price. I've had most of the legendary headphones at one time or another. I've used the Equinox, Cardas, Blue Dragon, Silver Dragon, and Zu Mobius cables with the HD650. The Zu was the clear winner, and it wasn't even close. I currently use the 650 with the Equinox (it was what I could get at the time), and keep wishing it was the Zu cable (recheck every morning; nope, still a bloody Equinox) -- I've let a couple of those Zu's go and always regretted it later. The Zu is unique in that it does the following:

* boosts the treble & sparkle (the 650 needs it) without broaching the point of harsh or fatiguing
* doesn't dry up the 650's nice midrange, like pure silver seems to
* tightens up the bass without making it leaner in the process
* excellent, pinpoint imaging

All the other cables fail on 1 or more of those points.

Found this olde thread when I was searching for whether or not Lavricables are worth it. I bought some C3 Cables for my HD650 that I use at home and it blew my mind how much of an improvement they made, so I thought about springing for the Lavricable Grands for the LCD-3s I'm using at work... just so so pricey.

I'm running those from the balanced outputs on a Sony PHA-3 and they are clearly superior to the stock Sennheiser cables. I was expecting a marginal difference, but I am no longer a cable skeptic now. 

I'm using 650s with Cardas Cable in balanced mode with its dedicated balanced amp....  great sound.
