I think I'm taking this to the next level. My phono preamp is done and sounds amazing! Here's a pic:

I was just listening to my old Frankie Goes to Hollywood 45RPM club mix of Relax, and even at less than 3W, my chest was thumping from the bass response. Nothing like a 15" driver. I really like my "new" speakers.

The 15W OTL is in the mail. I will now have two amps, a 15W OTL and a 3W cathode follower. So even though I just redid the XOs, I think bi-amping is in my near future. It's hard not to with these horn drivers.

So I picked up a Behringer DCX2496 active XO for a reasonable price and will start fiddling with it. For now the CFA will run the horns, but I think the long term plan is to build a pair of 300B OTL monoblocks to drive them and use the 15W OTL for the 416As.
