OOOPS!!! I forgot to mention Adcom GFP750. Ivanj, right on!
Don't spend too much on cables for passive preamps. AudioQuest DiamondBlack tended to work the best with passives. You can also get VanDenHul Type2. I've never heard F.T. audio but in general terms you simply ought to try any passive v.s. active that is 2x or 3x the price of passive and see the result. After that I'll guarrantee that you will forget about using active preamp.
