Tube (Lo Zin/lo gain) -buffer

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Hi!
I am planing to use the miniDSP 2x4 as an active pre-amp in my tube/horn system.
However the low input impedance (6K Ohm) perturb me, so I figure i should put a tube buffer (low input inpedance/ no gain) in front of it.

I prefer not going to CF-circuits as I Think they often sounds boring.
I figure a CG 6AS7/6080 or a CG 12B4A circuit could be of use.

Any sugestions for alternative cicuits?
