Hi David, good for you for getting rid of the 300i, I love Krell myself but somehow I think you made the right choice on getting the Pass Labs amp for your Khorus speakers.Something tells me that the Pass and Talon Khorus will have a better synergy than the Krell and Talon Khorus combo.
Now for the preamp, since your budget is around $1000 maybe a used Sonic Frontiers Line 1 or BAT VK-3i, the reasons I suggested these two were due to the fact that they both have balanced outputs, which in turn will work well with your Pass Labs amp.
Happy Hunting.
