I recently did this mod to my power amp.For a long time was running a Jensen Isomax Output transformer unit, to convert from unbalanced to balanced, and drive a long run of twisted pair cables to my power amp's electronically balanced inputs.
I recently opened up the amp and added a pair of JT-11Ps, as per Jensen's diagram; still using the unit's original XLR input jacks. Removed the output tranny unit and associated cables on the unbalanced preamp end, just threw on some WBT Nextgens on the twisted pair cables. As per the Jensen literature, I even grounded the shield of the cable (Belden 89207) on the preamp's chassis, instead of combining it with the low wire.
Is this still considered a balanced design? I did it mainly to clean up the number of connections in the chain, and feel I got an improvement in the sound. I now feel most folks who think they need to go “full blown balanced†for long cables, really just need to do this.
