Why not keep the existing layout, but insert a Magnequest B7 linestage transformer at the end. This allows a 12:1 voltage reduction, and balanced output. It does seem silly to go from balanced to single ended and back to balanced, but in terms of ease of set-up and design this is really an easy way to go.I have both the Siren Song, which I thoroughly enjoy, and the B7's used in a para-feed line pre-amp with a 76 driver. Nice system.
Go to Bottlehead.com to look for specs and info on the B7. Use the C4S devices for plate loading. Takes a while for the devices to break in (transformer, cap and C4S) but it is worth the time.
