Anyone have one? Currently running the 5435 (2005 model w/ 5v preouts) and would like to upgrade to 8v preouts. I will be running the rears off of it so the preamp must be functional. Don't like the looks of the 05 models or I'd just buy one new. Prefer newer and in great condition. Willing to trade + cash if you are interested. PM with offers. Thx
